Key Highlights

• Pre‑workout choices should match your session’s intensity and goals: carbohydrates and moderate protein improve high‑intensity and strength performance; low‑intensity activity often tolerates fasted training.
• Timing, meal composition, and individual factors (sleep, gut tolerance, training history) determine whether you feel stronger, recover faster, and preserve muscle mass.
• Test protocols, track perceived exertion and output, and adjust portions and timing until a repeatable pre‑workout routine consistently improves performance.

Introduction

Athletes and gym-goers face a simple yet consequential choice every training day: eat before the session or not. The decision influences energy, strength, endurance, recovery and even how the body partitions fuel between carbohydrate and fat stores. For some, a small banana and a scoop of whey unlock new personal records; for others, an early‑morning fasted run is convenient and produces desirable adaptations. The correct approach depends on the workout itself, the physiological state you arrive with, and the outcomes you prioritize — be that fat loss, hypertrophy, or maximum power output.

This article lays out clear, evidence‑informed guidance to make that pre‑workout choice predictable instead of experimental. You will find practical meal templates, timing strategies, supplement notes, and troubleshooting steps tailored to common training profiles: endurance athletes, strength trainees, HIIT participants, and recreational exercisers. Real‑world examples illustrate how small adjustments in the hour before a session can translate into measurable changes in effort, reps, and perceived exertion.

Why fueling matters: the physiology behind pre‑workout nutrition

Your muscles operate like a hybrid engine with two primary fuel pathways: carbohydrate (glycogen and blood glucose) and fat (free fatty acids). High‑power outputs — sprinting, heavy sets, fast intervals — depend predominantly on carbohydrate oxidation. The immediate source is blood glucose and muscle glycogen, both finite over a single session. Low‑intensity activity leans more on fat oxidation, a slower but larger reserve.

Hormones modulate this system. Cortisol and adrenaline rise when exercising in a low‑energy state; these hormones mobilize fuel but can also accelerate protein breakdown if energy availability is low. Consuming a carbohydrate‑containing snack before intense workouts blunts the cortisol spike, preserves glycogen, and reduces the risk of premature fatigue and muscle catabolism. Adding a moderate dose of protein before exercise supplies amino acids that support muscle protein synthesis and blunt post‑exercise breakdown.

Hydration sits beside fuel as a nonnegotiable nutrient. Even 1–2% bodyweight dehydration reduces strength, power and endurance. Electrolyte balance matters during prolonged sessions or when sweat losses are high.

Real‑world example: A competitive CrossFit athlete shifted from training fasted to eating 30 g of carbs plus 20 g whey before morning sessions. Over four weeks she reported higher rep counts on benchmark workouts and less muscle soreness — consistent with improved glycogen availability and reduced early fatigue.

Match fuel to intensity: tailoring pre‑workout strategy to the session

Understanding the energy demands of your workout guides the decision to eat. Break down sessions into three practical buckets.

Low‑intensity, long‑duration (LSD) sessions

• Typical activities: brisk walking, light jogging, long slow cycling, restorative yoga.
• Fuel reliance: higher proportion of fat oxidation; carbohydrate needs are modest.
• Strategy: If you ate a balanced meal 2–4 hours earlier you can usually train comfortably fasted. For very long sessions (90+ minutes), include easily digestible carbs during the workout.
• Example: Morning 45‑minute brisk walk after an overnight fast is acceptable; add a small snack (banana or energy bar) if you plan to extend the session.

Moderate to high intensity and strength sessions

• Typical activities: resistance training, circuit workouts, tempo runs.
• Fuel reliance: mixed; repeated lifting sets and tempo work increase carbohydrate demand.
• Strategy: A small to moderate carbohydrate dose plus 20–30 g of protein 30–90 minutes before the session improves performance and recovery. Avoid high‑fat or very high‑fiber meals close to the start to prevent GI discomfort.
• Example: Eating a rice cake with peanut butter and a whey shake 45 minutes prior to a 60‑minute strength session supports sustained power output.

High‑intensity, short duration (anaerobic) sessions

• Typical activities: sprints, maximal lifts, HIIT.
• Fuel reliance: heavily carbohydrate dependent.
• Strategy: Consume quickly absorbed carbohydrates 30–60 minutes before the session. If training takes place several hours after a prior meal, increase carbohydrate intake to top up glycogen.
• Example: 30–60 g of simple carbohydrates (sports drink or banana plus honey) 30–45 minutes before a sprint session improves sprint quality and number of repeat efforts.

Practical takeaway: A casual stroll tolerates fasted states. Heavy lifting and intervals require pre‑exercise carbohydrate to preserve performance and reduce catabolic hormone responses.

The ideal pre‑workout macronutrient mix: how much carbohydrate, protein and fat

Carbohydrate: the primary performance driver

• General guidance: For sessions shorter than 60–90 minutes, a pre‑exercise carbohydrate intake of 20–60 g (or 0.3–1.0 g/kg bodyweight) in the 30–60 minutes before exercise delivers usable glucose without excessive GI load. For larger pre‑event meals 2–4 hours before, aim for 1–4 g/kg depending on duration and intensity.
• Types: Use rapidly digestible options for close timing — white bread, rice cakes, bananas, sports gels or drinks. Complex carbohydrates like oats and sweet potatoes work well when eaten with a 2–3 hour buffer.
• Why: Rapidly absorbed carbs raise blood glucose and supply immediate ATP turnover for high‑power efforts.

Protein: protect and build

• Target: 20–30 g of a high‑quality protein source before resistance training promotes muscle protein synthesis and supplies amino acids during the session.
• Choices: Whey protein, Greek yogurt, egg whites, or lean poultry. For those on plant diets, consider pea or soy concentrates; combine complementing sources across the day to meet essential amino acid needs.
• Rationale: Protein blunts exercise‑induced protein breakdown and augments post‑exercise anabolic signaling when combined with carbohydrate.

Fat: limit before intense work

• Guidance: Keep pre‑workout meals low in fat when the meal is within 2 hours of exercise. Fat slows gastric emptying and can cause cramping or sluggishness in high‑intensity circumstances.
• Exceptions: For very long, low‑intensity sessions (e.g., multi‑hour hikes) including fat in the earlier meal supports sustained energy. For fat adaptation training (an intentional protocol), higher pre‑session fats may be used strategically but will reduce peak power.

Hydration and electrolytes: nonnegotiable

• Aim to start the workout well hydrated. A practical rule: 5–10 mL/kg of fluid in the 2–4 hours before activity. Sip additional fluids in the 10–20 minutes prior if needed.
• For sessions over 60 minutes with significant sweating, include sodium in your pre‑workout hydration (sports drink or salted snacks) to maintain plasma volume and reduce cramping risk.

Real‑world sample pre‑workout combinations

• 30–45 minutes before heavy lifting: 1 banana + 20–25 g whey or a small smoothie (200–300 mL skim milk, 1/2 banana, 20 g whey).
• 60–90 minutes before a long tempo run: Bowl of oatmeal with honey and a tablespoon of almond butter.
• 15–30 minutes before HIIT: 200–300 mL carbohydrate sports drink or a small gel plus water.
• For morning fasted cardio where the aim is fat loss: no meal required, but ensure hydration and consider a small caffeine dose for alertness.

Timing: when to eat for best results

Align meal size and composition with the time between eating and training.

Large meal (2–4 hours before)

• Composition: Balanced carbohydrate (1–4 g/kg), 20–40 g protein, small amount of fat.
• Use case: Morning workouts scheduled after a large midday or early dinner the previous day, or afternoon sessions after lunch.

Small meal/snack (30–90 minutes before)

• Composition: 20–60 g carbohydrate, 20–30 g protein ideally from quickly digestible sources, minimal fat and fiber.
• Use case: Morning training or when convenience requires a compact meal.

Immediate pre‑workout (0–15 minutes)

• Composition: Pure carbohydrate and fluids (sports drink, gel). Avoid concentrated fats or proteins.
• Use case: Short high‑intensity sessions where carbohydrate is the only immediate concern and gastric emptying is critical.

Tactical examples

• Weightlifting session at 7 a.m.: If you wake at 6 a.m., opt for 20–30 g carbs + 10–20 g protein in liquid form to minimize stomach load.
• Afternoon cross‑country run starting at 5 p.m.: A well‑balanced lunch 3–4 hours earlier with a light snack (rice cake or fruit) 60 minutes before is appropriate.
• Multi‑hour endurance event starting early morning: Consume a carbohydrate‑rich meal 2–3 hours before start (e.g., bagel + peanut butter) and a small top‑up closer to start time if needed.

Supplements that matter — practical, evidence‑based options

Caffeine

• Ergogenic dose: 3–6 mg/kg bodyweight taken 30–60 minutes before exercise enhances alertness, reduces perceived exertion and improves power and endurance in many individuals.
• Note: Tolerance varies. Start at the low end and avoid excessive late‑day caffeine if sleep is necessary.

Creatine

• Timing: Daily intake (3–5 g/day) maintains muscle creatine stores and improves short, high‑power outputs. Timing relative to workouts matters less than steady daily intake.
• Practical tip: Loading protocols (20 g/day for 5–7 days) are optional; consistent daily maintenance yields similar long‑term benefits.

Beta‑alanine

• Effect: Can reduce muscle acidosis in workouts lasting 1–4 minutes, improving performance for repeated high‑intensity bouts. Requires chronic loading (4–6 weeks).
• Side effects: Mild paresthesia at higher single doses.

Branched‑chain amino acids (BCAAs) and EAAs

• Evidence: Adding essential amino acids around resistance training supports protein synthesis. Whole protein sources (20–30 g whey) are more practical and often more effective than isolated BCAAs.
• Use case: If training fasted, a small EAA or whey dose pre‑workout can reduce muscle protein breakdown.

Sodium and electrolyte products

• Use during long or hot sessions to maintain plasma volume and prevent hyponatremia in activities exceeding 2 hours or with high sweat rates.
• Sports drink formulations are useful when carbohydrate and electrolyte needs coincide.

Practical caution: Supplements should complement, not replace, a sound nutrition plan. Prioritize whole foods; use supplements to fill specific gaps or deliver known ergogenic doses.

Fasted training: benefits, limits and how to do it safely

Fasted training — exercising after an overnight or prolonged period without calories — has proponents who cite enhanced fat oxidation, improved metabolic flexibility and logistical convenience. Evidence supports greater acute fat oxidation during low‑intensity fasted exercise, but the long‑term impact on fat loss is context dependent and often minimal once total daily energy balance is controlled.

Where fasted training makes sense

• Low‑intensity steady runs or aerobic sessions that emphasize fat oxidation and are short (<60 minutes).
• Individuals training primarily for convenience (early morning workouts) who prioritize adherence.
• Athletes using periodized nutrition strategies where some sessions intentionally restrict carbohydrates to encourage metabolic adaptations; these are best applied sparingly and within a structured program.

Where fasted training is a poor choice

• High‑intensity intervals, maximal efforts or heavy resistance sessions, where performance and quality of work matter.
• Long endurance sessions without planned fueling; performance and immune function may suffer.
• Populations at risk for hypoglycemia or those on insulin or insulin‑sensitizing medications.

How to manage fasted workouts

• Keep intensity moderate and duration short. Monitor RPE and readiness.
• Stay hydrated and consider black coffee (caffeine) for alertness if tolerated.
• If signs of lightheadedness, nausea or severe fatigue appear, stop and consume a carbohydrate snack.

Real‑world example: A recreational runner used fasted morning runs for two weekly recovery days to improve time efficiency and perceived fat oxidation. Her speed workouts were scheduled later in the day after a carbohydrate‑containing lunch, preserving quality work while gaining convenience.

Individualization: the algorithm for finding your pre‑workout sweet spot

No single pre‑workout meal fits everyone. Use a methodical approach to discover what reliably improves your output.

Step 1 — Define the goal

• Strength/power: prioritize fast carbs + protein before sessions.
• Endurance performance: tailor carbs to duration and intensity; include mid‑session fueling for events >60–90 minutes.
• Fat loss: consider strategic fasted low‑intensity sessions and manage total daily energy intake; avoid chronic underfueling around heavy lifting.

Step 2 — Start with a template based on session type

• Heavy lift or HIIT: 30–60 g carbs + 20 g protein 30–60 minutes prior.
• Moderate session: 20–40 g carbs + 15–20 g protein 60 minutes prior.
• Low‑intensity cardio: hydrate; optional small snack if needed.

Step 3 — Test and record

• Keep a short log: what you ate (item and time), perceived energy, RPE, reps/weights or distance/time, and GI symptoms.
• Test each variable for at least 7–10 sessions before adjusting further.

Step 4 — Refine

• If energy falls at 40 minutes, increase carbs or shift timing closer.
• If you experience GI upset, reduce fiber and fat, or move to more liquid options.
• If strength is compromised late in sessions, increase pre‑session carbohydrate or consider intra‑session fueling.

Step 5 — Lock in and periodize

• Once you find a combination that consistently improves performance, use it on key training days and competitions.
• Periodize pre‑workout fueling across cycles: heavier fueling near competition phases and strategic carbohydrate restriction during select training blocks if metabolic adaptation is a programmed goal.

Practical meal and snack ideas (by timing and training type)

Two to four hours before (substantial meal)

• Grilled chicken, white rice, steamed vegetables, small avocado.
• Bowl of oatmeal with honey, low‑fat Greek yogurt, and berries.
• Salmon, sweet potato, and a side salad (opt for lower fat if training soon after).

60–90 minutes before (light meal)

• Toast with jam and a boiled egg.
• Oatmeal with banana and a scoop of whey.
• Rice bowl with lean turkey and vegetables.

30–60 minutes before (snack)

• Banana + 20 g whey shake.
• Two rice cakes with honey.
• Small smoothie: 150–250 mL milk, 15–20 g whey, half banana.

0–15 minutes before (rapid carbs)

• 200–300 mL sports drink (30–60 g carbs per liter).
• Energy gel and water.
• Small portion of white bread with jam.

Hydration and electrolyte suggestions

• 2–4 hours pre: 5–10 mL/kg of water.
• 10–20 minutes pre: 200–300 mL more.
• For heavy sweaters: include 200–250 mL of a sports drink with sodium in the hour before.

Recipes that travel well

• Overnight oats (2–3 hours before a midday session): oats with milk, mashed banana, and a scoop of whey.
• Portable smoothie: blend whey, milk, frozen fruit and keep cold in insulated bottle.
• Rice cake stack: rice cakes layered with jam and a thin spread of nut butter for quick carb plus modest fat.

Special populations and safety considerations

Older adults

• Prioritize protein to minimize sarcopenia: 25–40 g of protein near training supports synthesis.
• Keep carbohydrate moderate and avoid long durations of fasted high‑intensity exercise.

Women and menstrual cycle considerations

• Energy needs and carbohydrate tolerance may fluctuate across the cycle. Many women report better performance and tolerance for carbs in the luteal phase; adjust intake and timing accordingly.
• Monitor symptoms and adapt; some athletes benefit from slightly higher carbohydrate availability around heavy sessions during lower‑energy phases.

People with diabetes or on glucose‑lowering medications

• Blood glucose response to exercise and pre‑exercise snacks varies. Measure blood glucose around sessions to develop a safe fueling plan.
• Hypoglycemia risk is real when taking insulin or sulfonylureas. Carry fast carbs and follow clinician guidance.

Pregnant or breastfeeding athletes

• Consult healthcare providers before training fasted. Energy needs increase during pregnancy; frequent fueling and hydration are commonly recommended.

Gastrointestinal sensitivity

• If fiber or fat provoke symptoms, switch to low‑fiber, low‑fat, liquid carbohydrate options pre‑workout.
• For runners with upper GI distress, consider testing different carbohydrate formats (liquid vs gel) during low‑stakes sessions.

Allergies and food intolerances

• Gluten, dairy, and nut allergies require substitutions (rice or potato-based carbs, plant proteins, seed butters). Maintain carbohydrate and protein targets with alternatives.

Medication interactions and medical conditions

• Review caffeine, stimulant supplements and chronic medications with a clinician for safety. People with cardiovascular conditions should follow medical advice before using ergogenic stimulants.

Troubleshooting common pre‑workout problems

Problem: Feeling weak or “flat” 20–40 minutes into training

• Likely cause: insufficient carbohydrate or poor timing.
• Fix: Increase pre‑session carbs by 10–20 g or move snack closer to start. If GI tolerates liquids, try a sports drink.

Problem: Nausea, cramping or reflux during workouts

• Likely cause: High fat, high fiber or overly large meal close to session.
• Fix: Choose low‑fat, low‑fiber, largely liquid or easily digestible carbs within the hour before training. Reduce meal size if training soon after eating.

Problem: Sleep disruption after caffeine

• Likely cause: Caffeine dose/timing conflicts with sleep window.
• Fix: Move caffeine earlier or reduce dose; 3 mg/kg is often effective and less disruptive than higher doses.

Problem: No change in body composition despite fasted cardio

• Likely cause: Energy balance determines fat loss; acute increases in fat oxidation don’t guarantee long‑term fat loss.
• Fix: Track daily calories and protein. Use fasted low‑intensity sessions for consistency, but don’t rely on them exclusively for fat loss.

Problem: Performance drops in late session

• Likely cause: Glycogen depletion or dehydration.
• Fix: Increase carbohydrate in the pre‑workout meal or add intra‑session carbs for sessions longer than 60–90 minutes. Ensure regular fluid intake and include sodium for heavy sweat losses.

Sample daily plans: matching meals to training times and goals

Goal: Strength and muscle growth — afternoon lifting session

• Breakfast (7 a.m.): Oats with milk, berries, 30 g whey — moderate carbohydrate and protein.
• Lunch (12 p.m.): Chicken, rice, mixed vegetables — balanced meal.
• Pre‑workout (4:30 p.m., 45 minutes before): Rice cake + banana and 20 g whey.
• Post‑workout: 30–40 g protein within 90 minutes and carbohydrate to refill glycogen based on session intensity.

Goal: Morning fasted fat‑loss cardio + evening strength

• Pre‑cardio (6 a.m.): Water, black coffee optional. Keep cardio low intensity and under 45 minutes.
• Post‑cardio breakfast (7:30 a.m.): Higher protein: omelet with vegetables, toast.
• Afternoon strength: Pre‑workout snack 45 minutes prior (banana + whey) to support performance.

Goal: Endurance event training (2–3 hour run)

• 3–4 hours pre: Bagel with peanut butter and honey.
• 30–60 minutes pre: Sports drink or gel depending on tolerance.
• During: 30–60 g carbohydrate per hour (adjust based on intensity and gut tolerance).
• After: 0.3–0.5 g/kg carbohydrate plus 20–30 g protein within 30–60 minutes to start recovery.

How to measure whether your pre‑workout routine works

Track objective and subjective metrics over several weeks:

• Objective: Weight lifted, number of reps at target intensity, time trials, pace, heart rate variability (HRV), session power.
• Subjective: RPE, perceived energy, alertness, mood, and recovery markers (soreness, sleep quality).
• Physiological: If available, monitor blood glucose, ketone trend for metabolic training, or use heart rate data to gauge effort.

If key performance markers show consistent improvement or feel easier at the same work rate, your fueling strategy is effective. If performance stalls or GI issues persist, iterate using the troubleshooting guidance outlined earlier.

Myths and clarifications

• Myth: Fasted training always burns more fat and therefore produces faster fat loss.
  • Clarification: Fasted exercise increases fat oxidation during the session but does not guarantee greater fat loss over time once total energy balance is equalized.
• Myth: You must always eat before lifting to gain muscle.
  • Clarification: Eating before heavy sessions improves acute performance and reduces muscle breakdown; however, total daily protein and training stimulus ultimately drive hypertrophy. Fasted lifting on occasion is acceptable for some people but not optimal for maximizing absolute performance.
• Myth: High‑fat pre‑workout meals boost endurance.
  • Clarification: Fat provides sustained energy for low‑intensity work, but pre‑workout high‑fat meals can impair high‑intensity power and cause gastrointestinal discomfort.

Practical checklist before your next session

• Did you align carbohydrate amount and timing with session intensity?
• Was protein included when strength or muscle preservation is a priority?
• Is the meal low in fat and fiber if eaten within 90 minutes of exercise?
• Are you hydrated? Have you consumed 5–10 mL/kg in the prior 2–4 hours and a top‑up before starting?
• Do you have a backup (sports drink or gel) in case energy drops mid‑session?
• If you plan to train fasted, is the session low intensity and short duration, or have you structured it intentionally into your program?

FAQ

Q: Should I always eat before workouts? A: No. Low‑intensity sessions can often be completed fasted if a prior meal has been consumed within the previous 2–4 hours. For high‑intensity or strength sessions, pre‑exercise carbohydrates and 20–30 g protein reliably improve performance and recovery.

Q: How many carbohydrates should I eat before a workout? A: For short to moderate sessions (up to 90 minutes), 20–60 g of carbohydrates 30–60 minutes before is a practical range. For longer or higher intensity efforts, aim for 1–4 g/kg consumed 2–4 hours prior and supplement during exercise as needed.

Q: Is caffeine a reliable pre‑workout aid? A: Yes. A dose of 3–6 mg/kg taken 30–60 minutes before exercise enhances alertness and often reduces perceived exertion. Begin at the lower end to assess tolerance and avoid disrupting sleep.

Q: What if I get stomach cramps when I eat before training? A: Reduce fat and fiber, move to more liquid carbohydrate options, or shift timing earlier to allow digestion. Testing different foods using low‑stakes sessions helps identify individual tolerances.

Q: Can I take creatine before workouts for immediate benefit? A: Creatine enhances short, high‑intensity performance when muscle stores are saturated. Daily maintenance (3–5 g/day) matters more than acute pre‑workout timing.

Q: Will fasted cardio accelerate fat loss? A: It increases fat oxidation during the session but does not reliably accelerate long‑term fat loss compared with fed cardio when total daily energy balance is matched. Use fasted cardio for convenience or specific training goals, not as a guaranteed shortcut.

Q: How much protein should I eat before resistance training? A: Aim for 20–30 g of high‑quality protein in the 60 minutes before training to support muscle protein synthesis and reduce breakdown during the workout.

Q: What are safe pre‑workout options if I have diabetes? A: Monitor blood glucose before and during sessions. Choose predictable, low‑GI options or simple carbs depending on medication and recent readings. Work with healthcare professionals to build a safe plan and carry fast carbs during exercise.

Q: How long before an event should I stop eating a large meal? A: Finish larger meals 2–4 hours before to allow digestion. For quick, high‑glycemic carbs, 30–60 minutes is typically enough.

Q: What if my performance improves but I’m not losing weight? A: Improved performance doesn’t necessarily equal fat loss. Track overall calorie intake, protein, and training volume. Adjust energy intake or add conditioning sessions if fat loss remains a priority.

Q: Are there any pre‑workout foods to avoid? A: Avoid high‑fat, very high‑fiber or unfamiliar foods within 90 minutes of high‑intensity training. Strongly spiced or greasy meals can provoke GI distress.

Q: How do I test and refine my pre‑workout routine? A: Use a short log to record food type, timing, RPE, performance metrics, and GI symptoms. Change one variable at a time and test over several sessions. Lock in what consistently improves your output.

Q: Can I take branched‑chain amino acids (BCAAs) before training to prevent muscle loss? A: Whole proteins or essential amino acid blends are preferable. BCAAs alone do not supply all essential amino acids necessary for optimal protein synthesis. A small dose of whey or EAAs before training is a practical alternative.

Q: Is there a difference between male and female pre‑workout nutrition? A: Basic principles apply to everyone, but hormonal fluctuations and subjective tolerance can alter need and timing. Women may notice cycle‑related shifts in appetite, energy and carbohydrate tolerance; adapt fueling accordingly.

Q: Do electrolytes before a workout help prevent cramps? A: Maintaining sodium and fluid balance reduces cramp and cramping risk for long, sweaty sessions. For workouts under an hour, plain water suffices for most people; for longer work, include sodium.

Q: How should I fuel during long endurance sessions? A: Consume 30–60 g carbohydrate per hour for moderate events; elite athletes may take higher amounts (up to ~90 g/hour) using multiple transportable carbohydrates. Hydrate and include electrolytes based on sweat rate.

Q: What’s the simplest pre‑workout snack that works for most people? A: A banana and a small whey shake or a sports drink provide quick carbohydrates and some protein without heavy digestion. Adjust portion size by bodyweight and session intensity.

Q: How long will it take to notice improvements after changing pre‑workout nutrition? A: Immediate performance benefits can be evident in a single session (especially for carbohydrate timing). For adaptations like improved training volume and recovery, expect consistent changes over several weeks.

Q: Who should consult a professional before changing pre‑workout routine? A: Individuals with chronic illnesses, on glucose‑lowering medications, pregnant athletes, and those with disordered eating or complex nutrition needs should consult a registered dietitian or medical provider.

Use this framework to move from guesswork to predictable pre‑workout fueling. Small, consistent changes in what and when you eat translate into more productive sessions, improved recovery, and better long‑term training outcomes.
