After a workout, aim for 0.25–0.4 g/kg (about 20–40 g) protein; body size, age, and goal set the exact post-training dose.
Why This Matters For Recovery And Gains
Training breaks muscle proteins and opens a window when fresh amino acids drive repair. A solid serving of rapidly digested, high-quality protein raises muscle protein synthesis more than training or eating alone. You don’t need fancy powders, but the amount and timing steer your results.
How Much Protein After A Workout? Targets By Goal
Most adults do well with a per-meal target based on body weight. Leading sports nutrition groups point to 0.25–0.4 grams per kilogram after training for younger adults, leaning toward 0.4 g/kg with age or very hard sessions. Another way to frame it: many people land in the 20–40 gram band when using typical foods or whey.
Quick Math: Per Meal Dose And Timing
The “per-meal” approach spreads protein across the day. Hitting a full serving after training acts as one of those anchors. If appetite is low, a shake works; if you’d rather chew, food works too. The table below converts body weight to a practical serving right after training.
| Body Weight | 0.25 g/kg (g) | 0.4 g/kg (g) |
|---|---|---|
| 50 kg | 13 | 20 |
| 55 kg | 14 | 22 |
| 60 kg | 15 | 24 |
| 65 kg | 16 | 26 |
| 70 kg | 18 | 28 |
| 75 kg | 19 | 30 |
| 80 kg | 20 | 32 |
| 85 kg | 21 | 34 |
| 90 kg | 23 | 36 |
| 95 kg | 24 | 38 |
| 100 kg | 25 | 40 |
| 110 kg | 28 | 44 |
What About The “Anabolic Window”?
You don’t need to slam a shake the second you rack the bar. The muscle-building signal stays elevated for hours, so eating a full serving within about two hours is fine. If your pre-workout meal was close to training, your window can be wider. The big rocks are total daily protein and steady servings across the day.
Leucine Threshold, Quality, And Age
Leucine sparks the muscle-building switch. Most adults hit that switch with a serving that contains around 2–3 grams of leucine, which usually lines up with 20–40 grams of high-quality protein. With age, the serving needed to hit the switch tends to rise, so leaning toward the upper end after tough sessions makes sense.
Dial The Dose To Your Training
Strength work and endurance work both benefit from an after-training protein serving, but the rest of the plate shifts. Lifters chase muscle and strength; runners and riders protect lean mass and support repair while also restoring glycogen.
Resistance Training Days
Aim for 0.3–0.4 g/kg right after lifting. Whey, milk, eggs, soy, and lean meats work well because they digest quickly and carry all essential amino acids. During a calorie cut, daily protein often needs to climb so you keep muscle while dropping fat.
Endurance Training Days
Go with ~0.25–0.3 g/kg protein along with carbohydrate. Pairing the two supports recovery, keeps immune health steadier, and helps you feel ready for the next session. A yogurt with fruit, chocolate milk, or a small turkey sandwich checks the box.
Daily Protein Still Runs The Show
Post-workout servings matter, but they sit inside a daily target. Most active adults progress on 1.4–2.0 g/kg per day, with 1.6–2.2 g/kg common for those lifting hard. Split this into three to five meals or snacks spaced every three to four hours, and include a solid serving at the meal after training.
Pre-Sleep Protein For Extra Coverage
Casein shakes or high-protein dairy before bed can raise overnight protein balance, especially on lifting days or in older adults. A serving around 30–40 grams about half an hour before sleep is a proven play. Cottage cheese, skyr, or casein powder all fit.
Food First, Supplements When Handy
Shakes offer speed and convenience. Food brings micronutrients, fiber, and variety. Most people blend both across the week. If dairy doesn’t suit you, soy, pea-rice blends, seitan, tofu, and legumes can cover the bases with planning.

- Lean beef, potatoes, and a side of beans
- Soy isolate smoothie with oats and peanut butter
- Cottage cheese bowl with fruit and nuts
Protein Sources And Serving Sizes
Here are handy serving sizes that deliver a solid post-workout hit. Mix and match to reach your target from the first table.
| Food | Serving | Protein (g) |
|---|---|---|
| Whey isolate | 1 scoop (30 g) | 24 |
| Milk (1%) | 500 ml | 17 |
| Greek yogurt | 200 g | 20 |
| Cottage cheese | 200 g | 24 |
| Eggs | 2 large | 12 |
| Chicken breast | 120 g cooked | 35 |
| Salmon | 120 g cooked | 30 |
| Lean beef | 120 g cooked | 33 |
| Tofu (firm) | 150 g | 18 |
| Tempeh | 150 g | 27 |
| Soy milk | 300 ml | 10 |
| Cooked lentils | 1 cup | 18 |
Putting It Together For Your Size And Schedule
Pick your weight from the first table. Choose a food combo from the second table to land near that protein target. Add fruit or grains after endurance work, and veggies or carbs to taste after lifting. If you train late, consider a pre-sleep dairy serving to cover the night.
Troubleshooting Common Snags
No Appetite After Training
Warm shakes, drinkable yogurt, or chocolate milk are easy when chewing feels tough. A salty snack can help bring appetite back so you can finish a solid protein serving within a couple of hours.
Plant-Based Or Dairy-Free
Use soy, pea-rice blends, or seitan to hit the leucine switch. Pair legumes with grains to round out amino acids, and keep servings a bit larger to reach the same total grams.
Cutting Fat While Keeping Muscle
Hold the per-meal after-training dose steady, but raise daily protein and keep lifting. Make sure carbs still support hard sessions so training quality stays high.
Evidence At A Glance
Sports nutrition groups point to 0.25–0.4 g/kg per serving after training and daily intakes around 1.4–2.0 g/kg for active adults, with 1.6–2.2 g/kg common for hard lifting. Timing is flexible across a couple of hours, and a 30–40 gram casein serving before bed can help overnight. Two moves stand out: hit a full serving after training, and meet your daily total by spacing protein across the day.
