Older studies showed bigger strength gains from weight training than newer ones, probably because today’s studies are better designed and less biased.

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.

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.

When people lift weights without pushing to their absolute limit, they actually get stronger faster than if they push to failure, as long as the total amount of lifting isn't the same. This comes from a big review of studies on adults.

Just because your muscles get bigger from lifting weights doesn't mean you'll get much stronger — the two don't really go hand in hand.

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.
