If you lift weights the same total amount each week, it probably doesn’t matter much whether you do it in 2 big sessions or 5 small ones—your muscles will grow about the same either way.

If you lift weights the same total amount each week, it doesn’t really matter whether you do it in one big session or spread it out over several days—your muscles will grow about the same either way.

Doing resistance training more often each week helps you get stronger more reliably, but it doesn’t always help you build bigger muscles — so frequency matters more for strength than for muscle growth.

Doing your workouts more often per week doesn’t seem to help you build more muscle, as long as the total amount of lifting stays the same.

People grow muscle at very different rates — but each person tends to grow their arms and legs similarly, no matter what weight they use. This means your genes and biology matter more than how heavy your weights are.

Lifting weights more often each week helps you build bigger muscles and get stronger, but after a certain point, you don’t gain much extra strength—though your muscles can still grow. If you keep the same total amount of lifting, doing it in more frequent, lighter sessions helps strength more than muscle size.
