When you lift weights more often, your muscles get bigger at a steady pace even if you go really high volume, but your strength gains slow down much faster — meaning your body builds muscle and gets stronger in different ways.

When you lift weights more often or heavier, your strength goes up fast at first but then slows down a lot quicker than your muscles growing — so strength gets tired of extra work sooner than muscle size does.

The more you lift weights each week, the less extra strength you gain from each additional session—but your muscles keep growing a bit more even when you train a lot, so strength gains fade faster than muscle growth.

Muscle size and strength don’t respond the same way to more training—strength peaks faster, so adding more sets helps muscle growth longer than it helps strength.

Doing more weightlifting gets you stronger, but after a certain point, extra sets don’t help much—way more than when you’re trying to build muscle size, where more work still gives you decent gains.

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.
