If you lift weights the same total amount each week, it doesn’t matter if you do it in one big session or split into three smaller ones—you’ll get just as strong and build just as much muscle.

Similar Assertions

If you train a muscle three times a week instead of once, and you end up doing more total work, you’ll get stronger and bigger muscles—better than if you kept the same total work.

90%

If you do the same workout three times a week instead of once, and you end up doing more total weight lifted, you’ll get stronger and build more muscle—because you’re doing more work overall.

If you're already fit and lift weights, doing 5 to 10 sets per muscle group each week will make you stronger—but doing more than that (like 15 to 20 sets) won't make you any stronger, no matter how hard you push.

If you're already fit and lift weights, doing anywhere from 5 to 20 sets per muscle group each week will make you stronger and build more muscle — and it doesn't matter much which number you pick within that range.

If young guys lift weights all over their body 3 times a week for 9 weeks, they'll get stronger — no matter if they switch up their exercises or stick to the same ones.
