Protein Needs for Strength Training - How Much Do You Actually Need?

Protein shakes right after training, chicken at every meal, constantly tracking grams — hardly any topic in strength sports gets taken as seriously as protein.

Rightly so, but often with the wrong numbers in mind.

The official recommendation isn't meant for you

0.8 grams of protein per kilogram of body weight — that's the reference amount healthy adults need, according to official nutrition guidelines. [1] It covers the baseline needs of someone who doesn't exercise. For someone who trains regularly, that number is simply too low. Building muscle noticeably raises your needs, because trained muscle requires more amino acids to repair and grow.

1.6 to 2.2 grams per kilogram - the target range

The most robust evidence shows the added benefit of more protein for muscle growth clearly flattens out at around 1.6 grams per kilogram of body weight per day. [2] If you want to play it safe, 1.6 to 2.2 grams per kilogram sits in a well-supported range — going beyond that usually adds no meaningful extra benefit for muscle growth. [2] For pure strength gains, the point where more protein stops paying off is even a bit lower, around 1.5 grams per kilogram. [3]

For someone weighing 75 kilograms, that works out to somewhere between 120 and 165 grams of protein a day — clearly more than the official reference amount of 60 grams, but also clearly less than some fitness myths suggest.

Distribution beats timing

Stubborn myths surround protein timing — chief among them the so-called anabolic window: the idea that protein has to be consumed within 30 minutes after training, or the training stimulus goes to waste. The evidence on this is clear: that narrow window doesn't really exist. [4] What matters is the total amount over the day, not the exact timing of intake.

What actually makes a difference is how you spread it across the day. The body can only use a limited amount of protein per meal for muscle building — roughly 0.4 grams per kilogram of body weight. [5] Spreading your daily target across at least four meals taps into that potential far better over the course of the day than cramming the whole amount into one or two large meals. [5]

What this means for your practice

OUR APPROACH AT 10 REPS

10 Reps doesn't track protein or count calories — that's deliberate.

What the app is for: delivering the training stimulus your protein can actually put to good use in the first place. The progression engine makes sure every session actually sets a growth stimulus, and the exercise detail shows your weight progression over time in black and white. Nutrition stays your call — 10 Reps handles the training that makes it worthwhile in the first place.

Conclusion: Enough Is More Reachable Than You Think

Protein needs for strength training are higher than the official reference amount, but lower than many myths claim. 1.6 to 2.2 grams per kilogram of body weight, spread across several meals a day — that's usually all it takes.

No need for a stopwatch diet or shaker panic right after training.
