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.

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.

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.

If you're a young guy lifting weights more often each week, you'll build more muscle and get stronger—but after a while, your strength stops improving fast, while your muscles keep growing a bit longer.

Lifting more weights each week makes you stronger, but the extra strength you gain from each additional set gets smaller faster than the muscle gains do.

Higher weekly resistance training volume leads to greater muscle hypertrophy in trained individuals.
