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...

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.

If you're a guy who's been lifting weights for a while, working out each muscle four times a week doesn’t make you stronger than doing it twice a week—as long as you're doing the same total amount of work.

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.

If you lift weights more often each week, you’ll likely get stronger faster—but that doesn’t always mean your muscles will get bigger. Strength and muscle growth might not follow the same rules.

If you spread your workouts over more days each week but keep the total work the same, you'll get stronger—but your muscles won't necessarily grow bigger.
