Key Highlights

• Most pregnant people with uncomplicated pregnancies should aim for regular moderate exercise—about 150 minutes per week—and can benefit from a mix of aerobic, strength, flexibility, and pelvic-floor work.
• Avoid high-impact contact sports, scuba diving, and activities with high fall risk; stop exercise and seek care for signs such as vaginal bleeding, chest pain, or decreased fetal movement.
• Tailor workouts by trimester, prioritize hydration and temperature control, and consult a healthcare provider and a certified prenatal instructor for personalized plans.

Introduction

Pregnancy changes the body in fundamental ways: cardiovascular output rises, joints loosen, balance shifts, and energy levels wax and wane. Against that backdrop, exercise often raises questions about safety, benefits, and appropriate intensity. Medical organizations and obstetricians now endorse physical activity during pregnancy for most people because the evidence links it to improved mood, reduced back pain, lower rates of gestational diabetes, and better overall fitness for labor and recovery.

This guide translates clinical recommendations into practical advice. It identifies who should avoid exercise, how to measure safe intensity, which activities work best, and how to modify movement across trimesters. It also offers realistic sample routines, strategies to protect the pelvic floor and core, and clear red flags that require stopping and seeking medical attention. The goal: empower pregnant people and their care teams to use exercise as a tool for health—safely and confidently.

Who should exercise and who should not: screening, contraindications, and clinical judgment

Exercise benefits most people with uncomplicated pregnancies, but certain conditions change the risk profile. Obstetric providers categorize contraindications as absolute or relative. Absolute contraindications are situations where exercise is not recommended because of a clear risk to the pregnant person or fetus. Relative contraindications may allow activity with careful monitoring and adapted intensity.

Common absolute contraindications include:

• Unexplained vaginal bleeding.
• Placenta previa after 28 weeks.
• Risk of preterm labor or a history of preterm labor.
• Ruptured membranes.
• Pre-eclampsia or severe hypertension.
• Incompetent cervix (cerclage) in some cases.
• Certain heart or lung diseases or other major medical conditions.

Relative contraindications where exercise might be possible under supervision:

• Some cases of anemia.
• Controlled gestational diabetes or mild hypertension, when activity is adapted and monitored.
• Moderate cardiovascular or respiratory disease.
• Symptomatic hypothyroidism or other endocrine disorders that are controlled.

Screen before you start: care providers typically perform a medical history, physical exam, and discuss pregnancy complications before clearing a patient for exercise. Ask about specific goals, past and current activity levels, and any symptoms such as pelvic pain or dizziness. When in doubt, defer to the clinician’s judgment. The risks of pushing through a problem outweigh the benefits of unsupervised exertion.

Case example

• Sarah, a 35-year-old who ran marathons pre-pregnancy and was diagnosed early with placenta previa, was advised to stop long-distance running and switch to walking and pool-based workouts until her placenta position resolved. Her care team tailored activity to protect against bleeding risk while preserving cardiovascular fitness.

How hard should you push? Measuring intensity and safety cues

Intensity matters more than style. The standard target for most pregnant people: moderate-intensity aerobic activity. Two practical ways to assess intensity:

The talk test

• If you can speak in full sentences during exercise but not sing, you are likely working at moderate intensity. If conversation is very difficult or you are gasping, reduce intensity.

Rate of perceived exertion (RPE)

• Use a 0–10 scale. Aim for 4–6 out of 10 during sustained aerobic work. Higher-intensity intervals are not forbidden for experienced athletes when cleared by a provider, but they require supervision and shorter duration.

Heart rate monitoring

• Heart rate targets used to be common but are less reliable now because pregnancy alters cardiovascular responses. Rely on perceptual tools like the talk test and RPE instead of fixed heart-rate zones unless advised by a clinician.

Breathing and effort cues

• Avoid breath-holding or intense Valsalva maneuvers, especially during heavy lifts. Keep your breathing steady and avoid pushing to the point of breathlessness or lightheadedness.

Balance and proprioception

• As the center of gravity shifts, balance diminishes. Favor stable, low-fall–risk modalities unless balance training is well supervised.

Adjust based on symptoms

• Nausea, severe fatigue, dizziness, chest pain, or contractions during or after exercise are signs to stop immediately and consult a provider.

Best activities for pregnancy: low-risk, high-benefit options

Low-impact exercises minimize joint stress and fall risk while supporting cardiovascular and muscular fitness. Recommended options include:

Walking

• Accessible and scalable. Walk at a pace that raises your heart rate but allows conversation. Add hills or incline gradually.

Swimming and water aerobics

• Buoyancy supports weight, reduces joint stress, and can relieve pelvic pressure. Water workouts are especially helpful in late pregnancy when body weight and swelling increase.

Stationary cycling

• Controlled, low-fall cardiovascular work. Adjust handlebars and saddle height for comfort as pregnancy progresses.

Prenatal yoga and modified Pilates

• Focus on mobility, breath work, alignment, pelvic-floor awareness, and relaxation. Avoid deep backbends, supine positions for long periods after the first trimester, and intense twisting that compresses the abdomen.

Strength training

• Two to three sessions per week with moderate loads using machines, free weights, resistance bands, or bodyweight. Emphasize compound movements for legs, hips, back, and core stabilization. Keep reps in a comfortable range (8–15) and avoid maximal lifts or breath-holding.

Pelvic-floor training (Kegels)

• Strengthening and learning to relax the pelvic floor helps reduce incontinence risk and supports labor. Work with a pelvic-floor therapist for personalized guidance if you have symptoms or uncertainty.

Prenatal group classes

• Look for instructors with prenatal certification. A well-led class provides exercise variety, social support, and modifications for changing bodies.

Practical recommendation

• Aim for a mix: at least 150 minutes of moderate-intensity aerobic activity per week, plus two sessions of strength training that focus on major muscle groups. Break aerobic work into manageable blocks (e.g., 5×30 minutes or 3×50 minutes across the week).

Activities to avoid and why: clear risks to avoid

Certain activities pose disproportionate risk to the pregnant person or fetus. Avoid the following:

Contact and collision sports

• Basketball, soccer, hockey, and other sports with risk of abdominal trauma can cause direct injury to the uterus or placenta.

High-fall-risk sports

• Skiing, horseback riding, rock climbing, mountain biking, and gymnastics involve falls that could cause maternal or fetal harm.

High-impact or jarring activities

• Repetitive high-impact jumping or plyometrics may increase joint stress and are less suitable for those with pelvic girdle pain.

Scuba diving

• Decompression risks to the fetus are real. Diving is contraindicated during pregnancy.

Hot, humid environments and activities that risk overheating

• Pregnant people have altered thermoregulation. Avoid hot yoga or exercising in extreme heat without careful hydration and temperature control, especially early in pregnancy during organogenesis.

Activities that compress major blood vessels

• Exercises performed while lying flat on the back for prolonged periods (after 12–16 weeks) can compress the inferior vena cava, reducing uterine blood flow. Modify supine work with elevated upper body or side-lying positions.

Extreme altitude activities

• High-altitude exposure risks hypoxia; discuss travel and activity with a clinician if you plan to exercise at altitude.

Why these are restricted

• The goals are to prevent abdominal trauma, avoid hypoxia or decompression injury to the fetus, and reduce fall or cardiovascular strain. Many of these activities carry small but meaningful risks that outweigh unclear benefits.

Sample workouts and weekly plans: practical blueprints

Below are practical, adaptable plans for three typical profiles—beginner, recreational exerciser, and experienced athlete—assuming medical clearance and an uncomplicated pregnancy.

Beginner: gentle introduction (first to third trimester)

• Aerobic: Walk 20–30 minutes, five days per week (100–150 minutes total).
• Strength: Twice-weekly sessions of 20–25 minutes: bodyweight squats, wall push-ups, bent-over rows with light bands, glute bridges, calf raises, 8–12 reps × 2–3 sets.
• Flexibility/pelvic floor: 5–10 minutes after workouts: pelvic tilts, cat-cow, and Kegels (3 sets of 8–12 contractions with relaxation).

Recreational exerciser: maintain fitness (first to third trimester)

• Aerobic: 30–40 minutes, five days per week at moderate intensity (150–200 minutes).
• Strength: Two to three sessions/week, moderate weights, 8–12 reps × 2–3 sets: split squats, Romanian deadlifts with light-to-moderate load, seated rows, shoulder presses with neutral grip, core stabilization work (bird-dog, side-lying leg lifts).
• Mobility: Prenatal yoga 1–2×/week for hip, thoracic spine, and pelvic alignment.

Experienced athlete: adapted training (with clinician clearance)

• Aerobic: Maintain base fitness; interval training may be possible in short bouts with extended recovery and monitoring of symptoms.
• Strength: Continue resistance work but reduce maximal loads, eliminate Valsalva, and avoid heavy compound lifts that cause breath-holding or instability. Prioritize controlled technique and higher repetitions.
• Recovery: Increase rest, prioritize sleep and nutrition, and reduce total weekly volume by ~10–30% depending on symptoms and stage of pregnancy.

Sample 30-minute strength session (recreational profile)

• Warm-up: 5 minutes brisk walking or cycling.
• Goblet squats: 3 sets × 10 reps (moderate weight).
• Seated row (band or machine): 3 × 12.
• Split-stance Romanian deadlift (dumbbell): 3 × 10 per side.
• Wall push-ups: 3 × 12.
• Glute bridges: 3 × 12.
• Side-lying clamshells: 3 × 15 per side.
• Pelvic-floor contractions: 3 sets × 8–12.
• Cool-down: Gentle stretching 5 minutes.

Modify every exercise if you feel dizziness, pelvic pain, or abdominal heaviness.

Strength training, the core, and the pelvic floor: what to do and what to avoid

Strength training protects the musculoskeletal system, supports posture, and prepares the body for labor and postpartum recovery. Pregnancy-specific considerations:

Technique and breathing

• Avoid breath-holding. Use steady exhalation on exertion phases.
• Favor controlled tempo; momentum increases joint load and fall risk.

Load and repetition

• Keep weights moderate. Err on the side of higher reps (8–15) and lower max loads. Reduce load progressively in later trimesters.

Exercise selection

• Prioritize lower-body and posterior chain: squats, hip hinges (modified deadlifts), lunges (stationary or reverse), and glute bridges. These build the muscles needed for everyday tasks and labor.
• Include upper-back work (rows, band pull-aparts) to counteract forward shoulder posture.
• Limit exercises that provoke diastasis recti (abdominal separation) or intense intra-abdominal pressure. Replace traditional crunches with core-stabilization and pelvic-floor oriented moves.

Diastasis recti

• Diastasis recti is separation of the rectus abdominis along the linea alba. It is common during pregnancy and postpartum. Avoid intense sit-ups, heavy loaded twisting, and wide-legged crunches if you notice a visible bulge or separation. Focus on transverse abdominis activation, pelvic tilts, and safely supervised core work.
• A simple self-check: from a supine semi-reclined position, gently lift the head and feel along the midline for a gap. If present, work with a pelvic-floor physical therapist to design appropriate progressions.

Pelvic-floor training

• Learn to contract and relax the pelvic floor; endurance and coordination matter. Over-tight pelvic-floor muscles can cause dysfunction just as weakness can, so balance is key.
• Seek a pelvic-floor therapist for persistent urinary leakage, pain with intercourse, or pelvic pain.

Postural adaptations and back pain

• Strengthen hip extensors and scapular stabilizers. Use mobility work for the thoracic spine. Avoid prolonged standing with an exaggerated lumbar lordosis; neutral spine during activity reduces strain.

Trimester-specific guidance: tailoring exercise from week to week

Pregnancy is not uniform. Each trimester brings distinct changes requiring specific adjustments.

First trimester (weeks 1–12)

• Symptoms: Fatigue, nausea, and breast tenderness are common. Early miscarriage concerns create anxiety for many.
• Approach: Maintain existing routines if comfortable. Reduce intensity during symptomatic days. Focus on shorter, more frequent sessions if nausea or fatigue interfere with longer workouts.
• Caution: Avoid sudden increases in exercise dose. Early embryonic development is not harmed by moderate exercise, but rigorous or exhaustive exertion is unnecessary.

Second trimester (weeks 13–27)

• Symptoms: Many experience renewed energy, reduced nausea, and growing belly. Weight gain accelerates and balance begins to shift.
• Approach: Increase low-impact aerobic work and strength training while prioritizing hip and core stability. Swimming and stationary cycling often feel especially comfortable.
• Caution: Monitor for round ligament pain or pelvic girdle pain; ease into movements that aggravate these.

Third trimester (weeks 28–40)

• Symptoms: Increased abdominal size, breathlessness with exertion, and pelvic stress. Sleep may be poorer.
• Approach: Emphasize mobility, posture, pelvic-floor training, and short, manageable cardio sessions. Use water exercise to offload weight and reduce swell. Replace supine exercises with inclined or side-lying alternatives.
• Caution: Conserve energy and avoid long high-intensity sessions. Avoid positions that compress large vessels.

Labor preparation

• Include breathing practice, controlled strengthening of glutes and legs, and pelvic-opening mobility. Practice positions that may be useful during labor: hands-and-knees, squatting, and side-lying supported movements.

Hydration, nutrition, temperature, and practical safety tips

Proper fueling and environmental control are essential to safe exercise during pregnancy.

Hydration

• Pregnant people have higher circulating volumes and require more fluids. Drink water before, during, and after exercise. Monitor urine color as a rough gauge—pale and clear typically indicates adequate hydration.

Electrolytes

• For workouts longer than one hour, or in hot conditions, supplementing with electrolyte-containing fluids can help prevent hyponatremia and cramping.

Nutrition

• Regular meals and balanced macronutrients support both maternal and fetal needs. Aim for protein-rich snacks after strength sessions to assist muscle recovery. Adjust caloric intake to reflect increased basal energy needs and exercise burn.

Temperature control

• Avoid overheating, particularly in the first trimester. Dress in layers, exercise in cooled or shaded environments, and move workouts indoors during extreme heat or humidity.

Clothing and footwear

• Supportive footwear that stabilizes the foot and reduces ankle roll becomes increasingly important as weight and pelvic changes occur. Consider a supportive, well-fitted sports bra and, later in pregnancy, a maternity compression top or belly support band if it feels helpful.

Timing and convenience

• Shorter sessions (10–20 minutes) multiple times per day can be as effective as longer workouts and may be easier to sustain with fatigue or nausea.

Travel and exercise

• Long travel increases deep-vein thrombosis (DVT) risk. During long flights drive breaks, move legs, and perform ankle pumps. Before traveling to high altitudes or remote locations for exercise, consult your provider.

Equipment and environment

• Swap unstable equipment (bosu, heavy free-balance gear) for balance-friendly alternatives. Prefer stationary equipment over activities with high fall risk.

Pack list for exercise class

• Water bottle, comfortable clothing, supportive shoes, slip-on shoes for post-workout comfort, a towel, and obstetric clearance documents if required.

Red flags and when to stop: clear signs to halt activity

Stop exercising immediately and seek medical attention if you experience:

• Vaginal bleeding.
• Dizziness or faintness.
• Shortness of breath before exertion.
• Chest pain.
• Severe headache.
• Muscle weakness or loss of coordination.
• Decreased or absent fetal movement after 28 weeks (or a change in regular pattern).
• Regular contractions or rupture/ leakage of fluid.
• Blurred vision or sudden swelling of hands/face (signs of pre-eclampsia).

If any unusual symptoms occur during or after exercise, contact your obstetric provider promptly. Early recognition and response reduce the risk of complications.

Managing common pregnancy complaints with exercise: back pain, pelvic girdle dysfunction, and swelling

Exercise is a frontline tool for many pregnancy-related discomforts when applied correctly.

Low back pain and sciatica

• Strengthening the glutes and core, improving thoracic mobility, and teaching neutral pelvic alignment reduce lumbar strain. Exercises such as glute bridges, quadruped leg lifts (bird-dog), and gentle hip hinges can be effective.
• Avoid heavy, poorly controlled forward flexion and deep spinal extension that aggravate symptoms.

Pelvic girdle pain (PGP)

• Symptoms: Aching across the pubic bone, pain with weight-bearing on one leg, and difficulty with movements like climbing stairs.
• Management: Reduce asymmetrical or single-leg loading in acute phases. Use pelvic support belts temporarily. Reintroduce controlled strength work for hip abductors, extensors, and core. Refer to a pelvic-floor or physiotherapist when pain limits function.

Lower-extremity swelling (edema)

• Elevation and compression socks help. Swimming and walking encourage venous return. Avoid prolonged standing; move frequently.

Varicose veins and hemorrhoids

• Avoid heavy straining. Maintain regular walking and leg exercises. Use appropriate fiber and hydration for bowel regularity.

Postpartum return-to-exercise: timelines, priorities, and red flags

Recovery after childbirth varies widely. The nature of delivery (vaginal, with complications, or cesarean) affects the pace of return. The immediate postpartum period focuses on rest, healing, and gradual reconditioning.

Early postpartum (first days to 2 weeks)

• Emphasize gentle walking, pelvic-floor activation, and breathing. Short walks multiple times a day help circulation and mood.
• Hospital discharge instructions often advise light activity as tolerated; avoid heavy lifting and intense exertion.

4–6 weeks postpartum

• Many providers perform a postpartum check at 4–6 weeks for uncomplicated vaginal births; C-section patients often receive follow-up at 6 weeks or as advised. Use this visit to get clearance for more intense exercise.
• If cleared, progress slowly: continue pelvic-floor work, introduce low-impact cardio, and resume light strength training. Monitor for urinary leakage, pelvic pain, or bulging at the midline (diastasis recti). If these occur, step back and consult a pelvic-floor therapist.

Pelvic-floor rehabilitation

• A targeted program improves incontinence, pelvic pain, and sexual function. Biofeedback or manual therapy can be helpful for complex cases.

Cesarean recovery

• Abdominal surgery requires slower progression. Gentle walking begins early, but return to abdominal loading and heavy lifting typically awaits at least 6–8 weeks and clinician clearance. Scar mobility work and progressive core activation under supervision assist recovery.

Graduated return-to-run plan

• For experienced runners aiming to return, use a walk-jog progression starting with short intervals. If urinary leakage or pelvic pain appears, regress and seek therapy. Expect timelines that vary from 6 weeks to several months.

Warning signs postpartum

• Heavy bleeding that soaks more than one pad per hour, fever, increasing incision pain or redness, calf pain or swelling, dizziness, shortness of breath, or persistent pelvic pain require urgent medical review.

How to choose a prenatal fitness professional and class

Choosing the right instructor or program improves safety and outcomes.

Credentials to look for

• Certifications in prenatal exercise from recognized organizations, courses in obstetric exercise science, or backgrounds in physiotherapy/physical therapy with prenatal specialization.
• Experience working with pregnant clients and documented willingness to modify workouts.

Class attributes

• Small class sizes for individualized attention.
• Clear warm-up, technique cues, and progressions.
• Options for modifications and alternatives for common pregnancy complaints.
• Environment that prioritizes hydration and rest breaks.

Questions to ask prospective instructors

• How do you modify for pelvic girdle pain, diastasis recti, or high-risk pregnancies?
• What ratio of instructor to participants do you maintain?
• Are you trained in emergency response and do you have clear protocols for adverse events?

Provider collaboration

• Prefer professionals who communicate with obstetric providers when necessary and who encourage clients to seek medical clearance before attending.

Real-world case studies: how exercise was adapted in different pregnancies

Case 1: Recreational runner becomes swimmer

• Jenna, 29, ran 4–5 miles pre-pregnancy. In the second trimester, pelvic pressure and fatigue made running uncomfortable. She switched to three 45-minute pool sessions per week plus two strength workouts focusing on the posterior chain. She maintained aerobic capacity, avoided pelvic pain flare-ups, and reported easier sleep.

Case 2: Managing gestational diabetes with exercise

• Priya, 34, developed gestational diabetes at 26 weeks. Her team recommended daily moderate activity—brisk walking and resistance training—along with dietary adjustments. She monitored blood glucose and avoided high-intensity intervals during glucose variability. She delivered at term with normal glucose control postpartum and required no medication.

Case 3: Elite athlete modifying training

• Maria, an elite cyclist, received clearance to continue training after an uncomplicated pregnancy, but with volume reduction and avoidance of long, high-intensity sessions by the third trimester. She substituted indoor trainer sessions for road work to reduce fall risk and focused on strength maintenance and pelvic-floor work. Her pregnancy proceeded without complication, underscoring that elite athletes can continue with careful adjustments.

These vignettes show adaptation, not uniform prescriptions. Individual needs, goals, and medical contexts differ.

Practical tips for common questions and scenarios

• Feeling dizzy during exercise: Stop, sit or lie down on your left side, hydrate, and reassess. If dizziness persists, seek medical attention.
• Breathlessness that limits talking: Lower intensity. Shorten intervals and increase rest.
• Nausea with exercise: Try shorter sessions, avoid exercising on an empty stomach, and time workouts to coincide with periods of lower nausea.
• Pelvic or groin pain: Modify to bilateral loading and avoid single-leg dynamic moves until evaluated.
• Headaches or vision changes: Stop and seek immediate care—these may signal hypertension or pre-eclampsia.
• Urinary leakage: Incorporate pelvic-floor training and consult a specialist if persistent.

Evidence snippets: what research says about pregnancy exercise benefits

• Aerobic activity is associated with lower risk of gestational diabetes and improved cardiovascular fitness.
• Strength and functional training reduce low-back pain and support postpartum recovery.
• Moderate exercise does not increase miscarriage rates in healthy pregnancies and is generally considered safe.
• Pelvic-floor therapy before and after delivery decreases urinary incontinence and improves recovery.

These findings support integrating consistent, moderate exercise into prenatal care for eligible individuals.

Legal and workplace considerations: exercising at work and liability

• Employers with on-site fitness programs should ensure instructors are trained for prenatal modifications.
• Pregnant employees should consult occupational health if work requires heavy lifting or prolonged standing. Reasonable accommodations may be needed.
• Fitness professionals should request medical clearance when clients disclose pregnancy and document adaptations and client consent.

Technology and wearable devices: how to use them wisely

Wearables can track steps, sleep, and perceived exertion. Use them as adjuncts, not replacements, for internal cues like the talk test. Avoid strict heart-rate targets unless advised. Some apps and devices now include prenatal-specific workout programs; choose those created or reviewed by clinicians or certified prenatal trainers.

Common myths and clarifications

• Myth: Exercise harms the baby’s growth. Fact: Moderate exercise supports healthy maternal weight gain, reduces gestational diabetes risk, and does not harm fetal growth in uncomplicated pregnancies.
• Myth: Running causes miscarriage. Fact: There is no clear evidence that moderate running in a healthy pregnancy increases miscarriage risk.
• Myth: You must stop exercising once you feel tired. Fact: Fatigue is common; adjust intensity and duration rather than stop completely. Gentle activity often improves energy.
• Myth: Crush sit-ups strengthen the core postpartum. Fact: Traditional sit-ups can worsen diastasis recti; prioritize pelvic-floor and transverse abdominis training instead.

Address myths by referencing professional guidance and clinical observation: individualized assessment beats blanket rules.

How to document and communicate with your care team

• Keep a simple exercise log with activity type, duration, intensity (RPE), and any symptoms. Share it at prenatal visits.
• Inform your provider promptly if you plan to continue high-intensity training or return to competitive sport.
• Seek a pelvic-floor physical therapist for persistent urinary, prolapse-like symptoms, or significant diastasis recti.

When to incorporate professional support: referrals and specialists

Consider professional support if:

• You have a high-risk pregnancy or complex medical history.
• You are an elite athlete seeking to continue training.
• You experience persistent pelvic pain, incontinence, or diastasis recti.
• You prefer structured guidance—certified prenatal instructors and pelvic-floor physical therapists provide evidence-based care.

A coordinated team—obstetrician, maternal-fetal medicine specialist (when indicated), physiotherapist, and certified trainer—yields the best outcomes for complicated or performance-focused pregnancies.

Putting it into practice: a month-by-month adaptative template

Month 1–3

• Focus: maintain pre-pregnancy habits if comfortable. Emphasize light strength, walking, and short cardio sessions. Prioritize sleep and nutrition.

Month 4–6

• Focus: build consistency. Increase swimming, cycling, and prenatal strength work. Start pelvic-floor training if not already done.

Month 7–9

• Focus: comfort and labor preparation. Reduce long workouts, favor water-based sessions, short cardio bursts, mobility, and pelvic-floor control. Practice labor positions and breathing.

Final weeks

• Expect variability. Short walks, mental rehearsal, and gentle mobility maintain activity. Follow care-team advice and conserve energy for labor.

This template requires individual tailoring based on symptoms and provider recommendations.

FAQ

Q: Is it safe to run during pregnancy? A: Running is safe for many people who were runners before pregnancy and have uncomplicated pregnancies. Adjust intensity and volume according to symptoms and balance. Switch to lower-impact options if pelvic or back pain, dizziness, or significant breathlessness occurs. Always seek clearance if you have risk factors.

Q: How much exercise should I aim for each week? A: Aim for at least 150 minutes of moderate-intensity aerobic activity spread across the week, plus two sessions of strength training focused on major muscle groups. If you were previously sedentary, start slowly and build to this target.
