Introduction

Trained strength, usable power and a steady pulse that pushes fitness forward: that’s the promise of the 25-minute full-body HIIT workout from Lindsey Bomgren on Nourish Move Love. Designed as a sequence of supersets, the session alternates heavy strength exercises with dynamic, often plyometric power moves. The result is a time-efficient workout that challenges muscle, balance and conditioning in the space of a coffee break.

This piece breaks down the workout’s architecture, explains why the structure produces both strength and metabolic gains, and translates the routine into practical guidance you can use whether you run regularly, have limited time, or are rebuilding strength after a break. Expect equipment notes, progression strategies, programming advice to combine this with running, and a detailed look at how the session reveals and corrects weaknesses that matter for everyday performance.

How the session is structured: five supersets, two-round flow

Bomgren’s routine organizes the 25 minutes into five supersets. Each superset pairs two exercises that are repeated twice before moving on to the next pair. Typically, the first exercise in each superset is strength-focused and loaded (heavier dumbbells, controlled tempo). The second exercise emphasizes power or dynamic movement: jumps, lateral bounds, burpees or rotational throws that drive speed and proprioception.

Warm-up The video opens with a rapid warm-up that prepares the nervous system. Bombardment of movement at a brisk pace jacks up heart rate quickly and primes the muscles and connective tissue for the alternating demands of strength and speed.

Work-to-rest rhythm Work windows are brief and intense. Short rests between the paired exercises, and modest recovery between supersets, maintain an elevated heart rate. The structure intentionally limits passive recovery, forcing the body to adapt to workload and metabolic stress while still applying load for strength adaptation.

Modification options A second trainer in the video demonstrates lower-impact alternatives. Those options keep the sessions accessible to people returning from injury, those with joint sensitivities, or anyone wanting more strength emphasis than plyometrics.

Why this structure works Pairing a strength move with a power move in immediate sequence capitalizes on two complementary stimuli. The strength exercise provides mechanical tension—essential for muscle recruitment and structural adaptation—while the succeeding power move recruits fast-twitch fibers and challenges coordination. Repeating each exercise twice per superset balances volume and intensity in a compact time window.

Why mixing heavy strength with plyometrics produces real-world power

A purely heavy, slow strength session builds force capacity. A pure plyometric session improves rate of force development. The superset approach fuses both outcomes.

Force capacity When a muscle can handle higher loads, its maximal force output increases. That carries over to everyday tasks and athletic actions: climbing hills, driving off the ground, or controlling a sudden change of direction. The strength components of Bomgren’s session—squats, lunges or presses with heavier dumbbells—deliver that load.

Rate of force development (RFD) Explosive moves like skater jumps, dumbbell burpees and bounding rapid-fire muscle fibers and coordination. These movements train the nervous system to generate force quickly. RFD is what separates a steady jog from a powerful sprint, and a controlled descent from a reactive cut. Pairing RFD training immediately after a strength stimulus primes the neuromuscular system and can magnify gains in both speed and athletic function.

Metabolic synergy The alternating structure produces metabolic demand disproportionate to the session length. Heavy lifts maintain muscular tension, and plyometrics spike heart rate and oxygen demand. Together they increase caloric expenditure, stimulate cardiovascular adaptation and enhance post-exercise oxygen consumption (EPOC), which can elevate calorie burn after the session ends.

Transfer to movement quality This blend improves movement under fatigue. Most real-world tasks occur when the body isn’t fresh. Training transitions between controlled load and dynamic movement teaches muscles to stabilize and produce force even while breathing hard and with a racing heart.

What to expect from a single session: pace, intensity and calorie burn

Expect intensity. The video’s pace is brisk from the first warm-up drill to the last rep. Short rests and back-to-back sets maintain high cardiovascular demand.

Perceived exertion You should anticipate elevated breathing and a pumping heart rate within minutes. If the session feels hard, that is the point. Still, the presence of a demonstrated low-impact alternative allows a smoother intensity curve if needed.

Calorie considerations Individual calorie burn varies by body size, sex, fitness level and effort. The reviewer logged about 213 calories over roughly 24 minutes. That figure reflects a relatively lean person who pushed reasonably hard. Heavier individuals or those who execute the plyometric moves with maximal effort will likely see higher burn rates. The combination of strength and plyometric work typically yields a greater calorie-per-minute ratio than traditional strength circuits that avoid dynamic movement.

Afterburn The mix of anaerobic power work and heavy lifting elevates metabolic stress and can prolong heightened metabolism after training. Expect some carryover calorie burn in the hours following the session.

Subjective outcomes Participants often report the session feels simultaneously demanding and efficient. The varied movement keeps perception of time short: the gym clock seems to move faster during well-paced, varied intervals.

Equipment and weight selection: why adjustable dumbbells help

Bomgren’s workout requires dumbbells and benefits from a range of weights. Each superset targets different anatomical regions with differing force demands. Lower-body compound movements tolerate—and benefit from—heavier loads. Upper-body presses and single-arm variations often need lighter weights to maintain form.

Why two sets of dumbbells are ideal Using a single weight for all exercises forces compromise: you may be strong enough for squats but struggle to press the same load overhead for multiple reps with clean technique. Two sets allow each muscle group to work at an effective intensity. Adjustable dumbbells are a space-efficient alternative to two fixed sets and make transitions faster.

Practical weight-selection rules

• Lower-body compound moves: choose a weight that allows 8–12 controlled repetitions with good depth and tempo. If you can perform more than 15 easily, increase the weight.
• Upper-body presses and rows: select a weight that challenges you between 10–15 reps per set. Keep strict form to protect joints.
• Plyometric moves: typically use lighter weights or none at all for maximum velocity. For example, perform dumbbell burpees with light pairs (or bodyweight) to keep movement speed high.
• If using a single pair of dumbbells and bridge weights by alternating single-arm or single-leg loading, reduce reps to maintain intensity and form.

Transition speed and safety Quick transitions help sustain heart rate, but avoid rushing so far that form deteriorates. Tack on one or two extra seconds to switch hands or set up a new weight rather than limp through sloppy reps.

Equipment alternatives If dumbbells aren’t available, kettlebells, sandbags, or resistance bands can substitute for most strength moves. For plyometrics, bodyweight suffices. Choose implements that preserve movement mechanics: load close to the center of mass for squats, use single-arm loads for unilateral work, and avoid awkward balances that compromise safety when fatigued.

Modifications and progressions: how to scale the workout for different goals

Bomgren’s session includes low-impact alternatives, which makes scaling straightforward. The workout can be made easier, harder, more strength-focused or more power-dominant.

Scale down (reduce impact and intensity)

• Replace skater jumps and broad jumps with side lunges and controlled step-outs.
• Substitute dumbbell burpees with plank-to-press or slow renegade rows.
• Increase rest between exercises (30–45 seconds) and between supersets (60–90 seconds).
• Use lighter weights and higher repetitions (12–15 reps) to reduce peak joint stress.

Scale up (increase load, velocity or density)

• Increase dumbbell load on strength movements while maintaining strict form.
• Add a third round of the superset instead of two rounds.
• Reduce rest and push for continuous movement through the entire 25 minutes.
• On plyometrics, add distance, height or speed (deeper skater jumps, higher tuck jumps).

Specialized progressions

• Strength emphasis: perform the first exercise for more sets or higher reps and keep power moves lighter or less frequent.
• Power emphasis: reduce the tempo on strength moves (fewer reps, heavier weight) and emphasize maximal velocity on plyometrics.
• Hypertrophy focus: increase total time under tension by slowing eccentric phases on the strength exercises while keeping plyometrics minimal.

Recovery progression If repeated soreness impacts subsequent training, reduce plyometric volume first. Ladder back into explosive work gradually, adding one plyometric exercise per week.

How this workout complements running and other sports

The reviewer is a runner who uses the session to develop lower-body force and core stability. That pairing is strategic.

Running economy and strength Resistance training increases the muscular stiffness and force capacity required to withstand the repetitive loading of running. Heavier lower-body lifts improve ability to sustain force through the stance phase. Converting that force into speed requires RFD training—exactly what the plyometric half of the superset promotes.

Hill running and power Hills demand high force output per stride and greater vertical impulse. The explosive elements in the HIIT session strengthen the muscles involved in propulsive phases—glutes, hamstrings and calves—and improve the neuromuscular drive needed for moderate sprints and hill repeats.

Core and stability for gait Rotational and unilateral components in the workout build the small stabilizer muscles that resist unwanted pelvic rotation and control limb alignment. Those muscles reduce wasted energy in the run stride and help blunt the cumulative stress that produces overuse injuries.

Cross-sport transfer Athletes in team sports, racket sports or mountain biking benefit similarly. The combined strength and power stimulus enhances acceleration, deceleration and lateral stability, all essential for cutting, sprinting and rapid direction changes.

Programming tips for runners

• Frequency: 1–2 full-body strength sessions per week. Replace one easy run with the workout on recovery days or schedule it after an easy day with 24 hours before a hard running workout.
• Timing: Avoid placing a heavy interval run or race the day after an intense HIIT strength session. Allow at least 24–48 hours for recovery if the subsequent run includes speed or long duration.
• Integration: Use the session as a supplement for off-season strength building or during base-building phases. During peak race preparation, reduce plyometric volume to prioritize run-specific work.

Real-world example A mid-pack marathoner who added two sessions per week of weighted strength plus plyometrics noticed less form breakdown on long runs and improved finishing speed for tempo work. The increased strength made late-race hills feel more manageable and reduced the frequency of calf soreness.

The session reveals weaknesses—how to interpret soreness and respond

Short, targeted sessions often expose poorly trained muscles quickly. Lateral movements in this workout highlight weaknesses that many runners and gym-goers neglect.

Lateral stability and side-to-side control Exercises such as skater jumps and side lunges loaded improperly reveal deficits in hip abductors, gluteus medius and the outer thigh complex. These muscles control frontal-plane motion and keep the knee aligned over the foot during gait and change of direction.

Interpreting soreness

• Localized soreness (for instance, gluteus medius or outside of thigh) after lateral work signals a training deficit. That is productive: targeted strengthening will correct it.
• Persistent pain that alters movement quality or lasts beyond 72 hours merits reduced load, mobility work and possibly professional assessment.
• Asymmetry (one side much more fatigued or sore) suggests unilateral weakness that benefits from single-leg variations and balanced programming.

Addressing weaknesses

• Add specific single-leg strength work: single-leg Romanian deadlifts, Bulgarian split squats, lateral step-ups.
• Integrate glute med activation drills before training: clamshells, banded lateral walks, monster walks.
• Use tempo and control: slow eccentrics on single-leg moves strengthen tendons and reduce re-injury risk.
• Reassess movement quality: film single-leg squats or lunges to check for knee valgus or hip drop. Corrective work should be technical and controlled.

Practical progression for lateral strength Start with bodyweight single-leg exercises twice weekly. Gradually add resistance and plyometric elements once control is established. Within four to eight weeks, progress to loaded lateral movements and higher-speed bounds.

Programming: frequency, recovery and a sample weekly plan

The workout is short, but intensity demands respect for recovery. Frequency, placement in the week, and recovery strategies determine whether the session improves performance or undermines it.

Recommended frequency

• General fitness: 1–2 sessions per week.
• Runners seeking strength and power: 1 full-body HIIT + 1 heavy strength session per week.
• Athletes needing power emphasis: 2 sessions per week, with careful load management and active recovery.

Recovery guidelines

• Sleep: Aim for consistent sleep quality; neuromuscular adaptations benefit from deep sleep.
• Nutrition: Prioritize post-workout protein and carbohydrate to support repair and glycogen replenishment. A 20–30 g protein meal or shake within two hours aids recovery.
• Active recovery: Low-intensity walking, cycling or mobility sessions the day after can accelerate flushing metabolic byproducts and reduce DOMS.
• Autoregulation: Use perceived exertion and readiness scores. When fatigue accumulates, reduce volume or swap one session for mobility or technique work.

Sample weekly plan for a time-crunched runner (who runs 4x/week)

• Monday: Easy run 45 min (zone 1–2).
• Tuesday: Tempo or interval run (e.g., 6 x 800m) + mobility.
• Wednesday: 25-minute Full-Body Dumbbell HIIT (Bomgren session) — focus on effort and form, light run or rest afterward.
• Thursday: Recovery run 30–40 min.
• Friday: Rest or cross-train (yoga, swimming).
• Saturday: Long run 90–120 min (depending on training phase).
• Sunday: Optional easy run 30–45 min or walk + mobility.

Alternative for strength-focused block

• Monday: Full-Body HIIT
• Wednesday: Heavy lifting (squat focus, deadlift variant)
• Saturday: Long run (reduced volume if strength sessions are heavy)

Adjustments for race week Replace HIIT with a low-volume strength maintenance session: lowered intensity, reduced plyometrics. Keep neuromuscular input without inducing excessive fatigue.

Common mistakes, form cues and safety considerations

The workout’s speed tempts shortcuts. Maintain control; otherwise, the risk of injury rises.

Common technical errors

• Allowing knees to collapse inward on lunges or squats. Cue knees tracking over toes and drive the knee out slightly to engage the glutes.
• Overextending lower back during heavy presses or deadlift variations. Maintain a neutral spine and engage the core before initiating each rep.
• Sacrificing hip hinge for shallow, quad-dominant movements. For posterior chain development, hinge from the hips in deadlifts and Romanian deadlifts, keeping a soft knee and long torso.
• Using excessive weight on plyometrics. Fast moves require speed; heavier loads slow execution and increase landing forces.

Form cues to use

• "Chest up, ribs down" for squats and lunges to preserve neutral spine.
• "Hinge from the hips" for deadlifts and Romanian patterns.
• "Land softly, absorb through hips" for jumps to reduce ground reaction forces.
• "Brace before you move" for presses and rotational moves to protect the spine.

Safety tips

• Warm up thoroughly: dynamic mobility, short activation drills for glutes and shoulders, and progressive movement rehearsal.
• If new to plyometrics, start with low excursions and bodyweight only.
• Prioritize landing mechanics: knees soft, hips back, and quiet feet.
• If you have a history of joint issues, select low-impact alternatives until strength and control improve.

When to seek professional input

• Sharp joint pain during movement.
• Persistent asymmetry or instability that compromises daily tasks.
• Recent return from significant injury or surgery—seek clearance and tailored programming from a licensed clinician or certified trainer.

Mobility, warm-up and cool-down templates

The video leads with a high-tempo warm-up, but a clear, purposeful warm-up sequence prepares the body while minimizing injury risk. A concise cool-down reduces stiffness and helps recovery.

Five-minute warm-up (dynamic)

• 60 seconds of light cardio: march or jog in place to raise core temperature.
• 30 seconds each: leg swings front-to-back (both legs).
• 30 seconds each: leg swings side-to-side (both legs).
• 30 seconds: banded lateral steps (light resistance) to activate glute med.
• 60 seconds: hip hinge practice with bodyweight or light kettlebell, 8–10 reps.
• 60 seconds: shoulder circles and scapular wall slides to prime pressing patterns.

Post-session cool-down (5–8 minutes)

• 2–3 minutes low-intensity walking or easy cycling to bring heart rate down.
• 2–3 minutes of mobility: deep hip flexor kneeling stretch, pigeon or figure-4 stretch for glutes, hamstring flossing.
• 1–2 minutes of thoracic rotation and doorway pec stretch to relax shoulders.

Optional recovery add-ons

• Foam rolling for quads and glutes.
• Light contrast showers or cold exposure to blunt acute inflammation when necessary.

Sample six-week progression to increase strength and reduce soreness

Week 1–2: Foundation

• Perform the 25-minute HIIT once per week, focusing on controlled technique and selecting conservative weights.
• Add one session of glute activation drills and unilateral strength (e.g., 3x8 single-leg Romanian deadlifts).
• Rest fully the day after HIIT or use active recovery.

Week 3–4: Load and velocity

• Increase dumbbell load on strength movements by 5–10% if technique remains solid.
• Increase plyometric intent: perform skater jumps at greater speed or increase range on bounds.
• Add an extra set to 1–2 strength moves in the HIIT, or perform the entire superset three times.

Week 5–6: Intensity and specificity

• Prioritize heavier strength in the first exercise (target 6–8 reps with heavier weight).
• Execute plyometrics with maximal intent for short, high-quality reps.
• If recovering well, perform the full HIIT twice per week with at least 48 hours between sessions.

Monitoring progress

• Track weights used and perceived exertion each session.
• Record soreness and readiness scores to adjust load.
• Re-test functional markers: single-leg squat depth, single-leg hop distance, or timed stair climbs to quantify improvement.

Translating one session into long-term gains: realistic expectations

A single session yields acute fitness benefits and a strong stimulus for adaptation. Long-term improvements require consistent application, progressive overload and adequate recovery.

Timeline for common adaptations

• Neural adaptations and coordination improvements: 1–4 weeks.
• Strength increases (measurable): 4–8 weeks with consistent lifting and progressive loading.
• Power development: 6–12 weeks, especially if plyometric quality improves.
• Transfer to running economy and race performance: 8–16 weeks depending on baseline training and integration strategy.

Avoid common pitfalls

• Overdoing plyometrics early: quality > quantity. High-quality explosive reps twice weekly yield better results than many low-quality reps.
• Same-for-everyone programming: tailor volume and intensity to your training history and goals.
• Neglecting recovery: strength adaptations stall without sleep, nutrition and proper spacing of hard efforts.

Real-world considerations: who benefits most and who should adapt the plan

Ideal candidates

• Time-pressed exercisers who need a comprehensive, efficient session that targets strength, power and conditioning.
• Runners who want to add strength and power to improve hill running, finishing speed and injury resilience.
• Athletes seeking a compact cross-training session to maintain neuromuscular readiness.

Adaptations for special populations

• Older adults: emphasize strength moves with slower tempos and lower impact power options. Keep plyometrics minimal and controlled.
• Beginners: reduce load, increase rest and focus on movement quality. Sub out jumps for controlled step-outs until landing mechanics are reliable.
• Those returning from injury: consult a professional. Prioritize single-leg stability, slow strength work and controlled range-of-motion before reintroducing high-impact moves.

Case vignette A recreational trail runner faced frequent lateral ankle soreness and fatigue on technical descents. After eight weeks of targeted supersets emphasizing unilateral strength and controlled lateral bounds, she reported firmer landings, less ankle rolling and faster recovery after long runs. Progress hinged on consistent single-leg work and gradual reintroduction of plyometric intensity.

Programming variations for different goals

Goal: Maximize strength

• Replace plyometric power moves with controlled heavy lifts or tempo-loaded repetitions.
• Increase rest between sets to 90–120 seconds.
• Focus on lower repetition ranges (5–8) on primary strength exercises.

Goal: Prioritize conditioning and calorie burn

• Keep plyometric volume high and move quickly between exercises.
• Use moderate weights and increase rep ranges to 12–15 on strength moves.
• Decrease rest to maintain elevated heart rate.

Goal: Improve lateral stability and balance

• Add single-leg loaded exercises and controlled lateral bounds.
• Emphasize slow eccentric control and tapered plyometric progression.

Goal: Maintain strength during heavy running blocks

• Reduce volume and plyometric intensity, focus on maintenance loads (2–3 sets of 6–8).
• Keep sessions once a week to preserve neuromuscular stimulus without inducing fatigue that compromises quality runs.

Cool-down: mobility and recovery specifics that matter

Ending a high-intensity session without specific mobility work leaves stiffness and shortens adaptation. Target areas under greatest stress: quads, glutes, hamstrings, calves, thoracic spine, and shoulders.

Targeted mobility sequence (10 minutes)

• Quad/hip flexor stretch (kneeling): 60 seconds per side.
• Hamstring flossing (banded or dynamic reach): 60 seconds.
• Pigeon or figure-4 for glute release: 60 seconds per side.
• Calf eccentric drop on step: 2 sets of 8 slow repetitions per leg.
• Thoracic rotations on foam roller: 1–2 minutes.
• Scapular wall slides and doorway pec stretch: 60 seconds.

Active recovery modalities

• Light cycling for 20–30 minutes at low intensity the following day improves circulation and reduces stiffness.
• Contrast baths or cold water immersion can help reduce soreness for some individuals but use sparingly to avoid blunting long-term adaptation.

FAQ

Q: How hard should I push the plyometric moves? A: Execute plyometrics with high intent but prioritize safe technique. Maximal speed over a controlled distance is the goal. If you sacrifice landing mechanics or knee alignment for speed or height, reduce intensity until you can maintain form.

Q: How many times per week should I do this workout? A: Once per week is effective for general fitness. Twice weekly can accelerate power and strength gains if you manage recovery and keep at least 48 hours between sessions. For runners, pair this session with easy run days, not before key interval or long run workouts.

Q: I only have one pair of dumbbells. Can I still do it? A: Yes. Use single-arm or unilateral variations to increase intensity without heavier loads. Reduce reps to maintain quality. Adjustable dumbbells are the best long-term solution for seamless weight changes.

Q: I’m a beginner. Can I do the full session? A: Start with lighter weights, greater rest and the low-impact alternatives. Prioritize learning movement patterns and landing mechanics. After two to four weeks, increase intensity progressively.

Q: Will this workout help me run faster? A: The strength and power elements enhance the muscles and neuromuscular pathways that contribute to running speed, especially on hills and during finishing surges. Improvements depend on consistent integration and how the sessions are scheduled relative to running training.

Q: What if I feel too sore after the workout? A: Expect some delayed-onset muscle soreness, especially in undertrained muscle groups. Apply mobility, light active recovery and adequate nutrition. If soreness prevents normal movement or persists beyond a week, reduce volume and seek professional input.

Q: Can this session replace my regular strength routine? A: It can serve as an efficient hybrid that replaces one full strength session. For specific strength goals (e.g., maximal strength or hypertrophy), supplement with dedicated heavy lifting days.

Q: Is it safe if I have knee pain? A: If knee pain is structural or persistent, consult a clinician before attempting plyometrics. Use low-impact alternatives and prioritize strengthening the posterior chain and glute med. Modify or avoid high-impact moves until pain is managed.

Q: How should I warm up before the session? A: A quick dynamic warm-up that elevates heart rate, activates the glutes and primes hip hinge and shoulder mechanics suffices. Bomgren’s video moves quickly through warm-up; if you prefer a steadier ramp-up, allocate an additional 5 minutes.

Q: How do I track progress? A: Log weights, reps, subjective effort and how you recover after a session. Add objective tests such as single-leg hop distance, 10-second max-effort sprints, or timing a stair climb. Reassess every 4–6 weeks.

Q: Can older adults do this workout? A: Older adults benefit from the strength and power stimulus but should reduce impact, prioritize balance and progress cautiously. Low-impact power alternatives and longer recovery windows are recommended. Consult with a healthcare professional for personalized guidance if there are existing health concerns.

Q: Does this workout cause muscle bulking? A: When combined with typical endurance training or bodyweight activity and without an aggressive calorie surplus, this format is unlikely to cause significant hypertrophy. It builds functional strength and neuromuscular power more than large muscle mass increases.

Q: What is the minimum equipment I need? A: A pair of dumbbells (ideally two weights or adjustable), a small clear area for lateral movement, and a mat for floor-based moves are sufficient.

Q: How much rest between supersets? A: The workout is designed with short rests. Rest 30–60 seconds between the two sets making the superset complete, then 60–90 seconds between supersets if required. Adjust based on fitness and goal.

Q: Should I eat before the workout? A: A light carbohydrate snack (banana, toast with jam) 30–60 minutes before can provide quick energy for high-intensity intervals. Post-workout, prioritize a mix of protein and carbs to aid recovery.

This 25-minute dumbbell HIIT session represents an efficient, multi-dimensional approach to fitness. It blends heavy, loaded strength with dynamic power moves in a way that builds usable force, elevates conditioning and exposes functional weaknesses for targeted correction.
