Understanding Results

Formula

The calculator combines your inputs to produce four things: a short cooldown plan, protein and carbohydrate targets for the next meal, fluid and sodium guidance, and a sleep window. Protein uses body‑weight math (~0.25–0.40 g/kg; default 0.30 g/kg) scaled slightly by intensity. Carbs scale with session type and duration—endurance and interval days sit higher than short strength sessions.

Fluids start with a quick starter (~7 ml/kg) and add ~600 ml per training hour adjusted by intensity, heat, and sweat rate. Sodium is shown per hour (~300–600 mg/h for most; higher for hot, long days) to help you decide between lightly salted food and an electrolyte drink.

Reference Ranges & Interpretation

Most people recover well when protein lands near 0.30 g/kg after training and total daily protein is adequate. Carbs are most critical when you have another hard session within 24 hours or you train for endurance; otherwise, the middle of the range works. For hydration, steady sipping beats chugging. You should feel normal thirst and avoid headaches or frequent nighttime bathroom trips.

Treat the plan as a baseline. If your first two sets of the next workout feel flat, increase carbs and fluids after hard days. If you feel heavy or sleep is disrupted, bring the upper ends down slightly.

Assumptions & Limitations

These are educational estimates. The tool cannot factor in every variable (illness, injury, under‑fueling, new exercises, heat acclimation). If you have a medical condition or specific nutrition needs, consult a qualified professional. When unsure, train lighter, extend your cooldown, and prioritize sleep.

Complete Guide: Post Workout Recovery Calculator: Cooldown and Nutrition

Use the post workout recovery calculator for a cooldown, hydration, protein and carb targets, plus a sleep plan tailored to your session to speed recovery. The idea is simple: turn what you just did in the gym or outside into a short, specific plan you can follow right away. A good recovery routine is not about fancy hacks—it is about doing the basics well and consistently.

This tool prioritizes four things you can control after a session: a short cooldown, protein and carbs, hydration with enough electrolytes, and a realistic wind‑down for sleep. The output adapts to your session type, duration, and intensity, and it scales with your body weight.

How this post workout recovery calculator works

Recovery has many moving parts. You are restoring fuel (glycogen), repairing tissues, and settling your nervous system. Our calculator blends session type (strength, endurance, HIIT, or mixed), duration, intensity (RPE), body weight, training conditions, and your sweat profile to suggest a practical plan. It uses widely accepted sports nutrition ranges rather than invented numbers.

Protein is based on body weight—roughly 0.25–0.40 g per kilogram in a single post‑workout meal, with 0.30 g/kg as a simple default. Carbs adjust by session type and length, rising for longer endurance or interval work and staying moderate for shorter strength sessions. Fluids scale with duration, conditions, and how heavily you sweat. Sodium is given per hour, so you can judge whether you need a pinch of salt or an electrolyte drink.

Finally, sleep is the ultimate recovery tool. We suggest a sleep target window (usually 7.5–9 hours) and a bedtime range if you enter when your workout ended. If you train late, the plan favors wind‑down tactics that help you fall asleep sooner without sleep aids.

Nothing here is a hard rule. The calculator gives you a smart starting point so you do not have to guess. As you use it, notice how the first two sets of your next workout feel and adjust next time—slightly more carbs after very hard days, or a bit less if you felt heavy. That feedback loop is how you personalize recovery.

Cooldown basics and timing

A cooldown does three useful things: brings your heart rate down smoothly, reduces the “buzz” from intense work, and buys time to do a couple of targeted mobility drills. You do not need to stretch for half an hour. Five to fifteen minutes is plenty for most sessions.

After strength or mixed classes, 6–10 minutes is enough: a short walk or easy bike, some slow nasal breathing, and 2–3 mobility drills for the areas you trained. After endurance or interval work, lean toward 10–15 minutes with a slower ramp‑down and a little more leg mobility. If your session was long (75+ minutes) or very hard (RPE ≥ 8.5), stay toward the high end of the range.

The calculator summarizes this as check‑off steps you can do on autopilot. If you are crunched for time, keep the breathing and one mobility drill—those two minutes do a lot for how quickly you feel settled.

Protein after training: how much and why it works

Protein gives your body the building blocks to repair muscle. Research consistently supports a practical range for a single meal after training: roughly 0.25–0.40 g/kg of body weight. For a 75 kg person, that is about 19–30 g; for 90 kg, 23–36 g. Our default target is 0.30 g/kg because it is easy to remember and hits the mark for most people.

You do not need to chug a shake within two minutes of your last rep. The “anabolic window” is more flexible than that. A simple rule is to eat within 30–60 minutes of finishing. Your total daily protein matters most, but a solid post‑workout meal helps recovery and appetite control later in the day.

If you prefer food over shakes, easy options include Greek yogurt with fruit and honey, eggs and toast, chicken and rice, or tofu with noodles. If you are training twice per day, the upper end of the range is more helpful. If your session was lighter, the lower end is fine.

A quick portion guide: many milks and yogurts provide 8–18 g of protein per serving; 3 large eggs bring ~18 g; 100 g of cooked chicken has ~27 g; 100 g of firm tofu has ~12–14 g. Mix and match to reach your gram target without overthinking.

Carbs to refuel glycogen without guesswork

Carbohydrates refill the glycogen you burned. For endurance or interval sessions, aim for roughly 0.8–1.2 g/kg in the first 1–2 hours, depending on how long and how hard you went. For strength‑focused sessions, 0.3–0.8 g/kg works well. The calculator picks a smart range based on your input.

If you have another hard session in the next 24 hours, shifting toward the high end of the range is a good idea. If you are in a calorie deficit or you train only a few days per week, the lower end is often enough. Add produce and a little fat to round out the meal.

Practical carb portions: a medium banana is ~27 g, a cup of cooked rice ~45 g, two slices of toast ~24–30 g, a cup of berries ~15 g, and a cup of orange juice ~25 g. Combine 2–3 items to land inside your target.

Fluids and electrolytes: drink enough, not endlessly

Hydration needs vary widely. A simple starting point is to take a few good sips immediately after training and continue drinking in the next 1–2 hours. Our output scales fluid needs with session length, conditions, and your sweat rate profile. Heavy sweaters in hot conditions need more; light sweaters training indoors need less.

Sodium replaces what you lose in sweat. A practical range during and after training is about 300–600 mg per hour for most recreational athletes, higher for long, hot events. The calculator shows a per‑hour sodium number so you can decide whether to add a pinch of salt to food or use an electrolyte drink. If you want a fuller daily hydration target, the Hydration Calculator is a helpful companion.

For a simple mental model, think “sip‑coast‑top‑off”: sip right after training, coast with small drinks for an hour or two, and top off if urine is very dark or you still feel thirsty. You should feel better within 20–30 minutes of starting fluids after a hard session.

If you notice headaches, extreme thirst, or muscle cramps after long hot workouts, you likely under‑did fluids and sodium. If your stomach feels sloshy or you are running to the bathroom constantly, you may be over‑doing it. Use the plan as a baseline and adjust by feel.

Sleep and late sessions: set up the win

Sleep is when your body closes the loop on recovery. We suggest a nightly target, usually 7.5–9 hours depending on how hard and how long you trained. If you enter when your workout ended, you will see a simple bedtime window that works well for most people. Finish late? Dim lights, cool the room, and limit screen time for the last hour of the day.

Caffeine lingers. If you train in the evening, avoid caffeine within at least 6 hours of bedtime. If sleep quality is inconsistent, consider a short daytime nap on heavy training days rather than another late coffee. The Sleep Calculator and Sleep Efficiency Calculator can help you plan.

You do not need perfect sleep to recover. Aim for “good enough” most nights and balance the week. On days you feel flat, shift to a lighter session or a rest day. Use the Rest Day Calculator or the Muscle Recovery Calculator to time your next harder effort.

If late training is part of your routine, build a wind‑down kit you can do on autopilot: 2–4 minutes of slow breathing, a warm shower, a cool, dark bedroom, and a set lights‑out window. Consistency matters more than perfection.

Example recovery playbooks

Heavy leg day (60–75 min, RPE 8–9): Cool down 8–12 minutes: easy bike + breathing + hip and ankle mobility. Eat ~0.30 g/kg protein and ~0.5–0.8 g/kg carbs. Sip 0.5–0.8 L of fluids in the next hour with a light pinch of salt. Sleep 8–9 hours if possible.

Intervals on the track (40–50 min, RPE 9): Cool down 10–12 minutes: shuffle jog to walk, then breathing. Carbs closer to 0.8–1.0 g/kg and the usual 0.30 g/kg protein. Fluids ≈ 0.6–1.0 L in the first 90 minutes; add 300–600 mg sodium per hour if it was hot.

Long ride or run (90–120 min, RPE 7–8): Cool down 10–15 minutes. Eat on the higher end of carbs (1.0–1.2 g/kg) with 0.30 g/kg protein. Hydration likely 1.0–1.5 L in the two hours after. Plan for 8–9 hours of sleep or a short nap if bedtime is late.

Mixed class (45–60 min, RPE 7–8): Cool down 8–10 minutes. Aim for mid‑range carbs (0.5–0.8 g/kg) plus 0.30 g/kg protein. Fluids 0.5–0.8 L, adjust for the room and sweat rate. Sleep 7.5–8.5 hours.

If you train twice per day, split recovery into two smaller meals and be deliberate with sodium and fluids. Small, frequent meals sit better for many athletes when sessions are close together.

Common mistakes to avoid after training

Skipping the cooldown entirely is the most common miss. You do not need to foam roll for ages, but two minutes of slow breathing changes how you feel. Another frequent mistake is under‑eating protein or delaying it too long on busy days. Keep simple options on hand—yogurt, milk, eggs, protein powder, or ready‑to‑eat tofu.

On the carb side, some people err both ways: far too little after long endurance work, or far too much after short strength sessions. Let your session length guide you. Hydration mistakes show up later as headaches or restless sleep. If your workout room was hot or you sweat heavily, include sodium on purpose.

Finally, screen time in bed can undo a great day. A short wind‑down and a set bedtime window make recovery feel easier the next morning.

Two more to watch: stacking caffeine late into the afternoon, and random supplements that disrupt sleep. For most people, a consistent routine beats extras. Save money and build habits.

Adjusting the plan for fat loss, muscle gain, or performance

For fat loss, keep protein high and shift carbs toward the lower end of the range unless you have a long endurance day or a second session. Recovery comes first; do not turn every day into a crash diet. The Calorie Deficit Calculator can help you set a realistic weekly target.

For muscle gain, protein stays similar while carbs live mid‑to‑high on most training days. Focus on strong sleep and consistent training volume. Use the Protein Calculator and Maintenance Calorie Calculator to anchor your intake.

For body recomposition, keep protein steady and use carbs as a lever: more on hard days, fewer on light days. Sleep consistency usually does more for recomposition than tiny macro tweaks.

For performance, match carbs to your training. Long or intense days favor the upper end of the range, and back‑to‑back sessions need deliberate refueling. Track how you feel on the first two sets of your next workout—if bar speed is slow or legs feel empty, increase carbs a bit after hard days.
