Protein for recovery: how much and when
Training breaks your muscles down; protein helps build them back stronger. But you don't need a tub of powder or a stopwatch by the gym door. Hitting a sensible daily total — spread across the day — does most of the work.

Every run, ride, or lifting session creates tiny tears in your muscle fibers. Protein supplies the amino acids that repair and reinforce them, which is how you adapt and get fitter. For active people, the everyday recommended minimum is often too low — endurance and strength athletes generally need noticeably more to recover well.
Why protein matters for recovery
Recovery is when fitness actually happens. After hard training, your body ramps up muscle protein synthesis for roughly a day or more, and dietary protein is the raw material that fuels it. Under-eat protein and you recover slowly, feel persistently sore, and adapt less from each session. Hit your target and you bounce back ready to train again.
You don't grow stronger during the workout — you grow stronger while you recover from it, and protein is the building block.
How much per day
Daily total is the lever that matters most. Practical targets for active people:
- General active adults: about 1.2–1.6 g of protein per kg of body weight per day.
- Endurance athletes: roughly 1.2–1.6 g/kg to repair training stress.
- Building muscle / strength: around 1.6–2.2 g/kg per day.
For a 70 kg athlete, that's roughly 84–154 g per day depending on goals. Spreading it across 3–4 meals of about 20–40 g each is more effective than loading it all into one.
Timing and the "anabolic window"
The old idea that you must drink a shake within 30 minutes or "waste" your workout is largely overstated. The recovery window is more like several hours wide. That said, having a protein-containing meal or snack within a couple of hours of training is a sensible, easy habit — especially if you trained fasted or won't eat a full meal for a while.
A practical post-session target is about 20–40 g of protein, paired with some carbs to refill energy stores. For how carbs fit into the picture, see what to eat before a run.

Best protein sources
Whole foods cover most needs; powder is just convenient. Solid options and their rough protein per serving:
- Chicken breast — about 30 g per 100 g cooked.
- Greek yogurt — roughly 15–20 g per cup.
- Eggs — about 6 g each.
- Lentils & beans — around 8–9 g per half-cup cooked (great plant options).
- Tofu, tempeh, and edamame — solid plant-based picks, ~8–15 g per serving.
- Whey or plant protein powder — about 20–25 g per scoop when whole food isn't handy.
A simple recovery routine
Set a daily protein target based on your weight and goal, then build each meal around a palm-sized protein source and aim for a snack or meal after training. Keep it boring and consistent — that beats perfect timing every time.
