If you lift weights regularly and increase how much you lift over time, your strength goes up more than your muscles get bigger — at least in young guys who already train a lot. So, getting stronger isn’t just about getting bigger muscles.

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.

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 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.

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.

Doing more sets of weightlifting in one session can help you build bigger muscles and get stronger, but after a certain point, doing even more sets doesn’t help much—around 2 sets is enough for strength, and 11 sets is enough for muscle growth.
