Even if you train a muscle every day, it can still get stronger — as long as you do it right.

If you're already experienced with weightlifting, doing full-body workouts every day gives you the same muscle and strength gains as doing different muscle groups on different days, as long as you do the same total amount of work each week.

If you lift weights more often each week, you’ll likely get stronger—but only up to a point. After a certain number of sessions, doing even more won’t help much more.

Even if you lift the same total amount each week, spreading it across more days can still make you stronger—frequency matters on its own.

Lifting weights more often helps you get stronger, but after a certain point, you don’t get much stronger no matter how much more you lift—plus, this slowdown happens sooner for strength than for muscle growth.

If you lift the same total amount of weight each week, it doesn’t matter if you spread it out over 5 days or do it all in 1–2 days — you’ll get the same strength and muscle gains.
