The muscle growth from drop sets was noticeably bigger than from regular sets, based on how scientists measure the size of the effect.

When you train to near failure, doing drop sets doesn’t make your muscles grow bigger than doing regular sets — both methods build muscle about the same in young men.

Even if you do the same total amount of work, drop sets don’t make your muscles grow more than regular sets — whether you match the weight lifted or not, the results are about the same.

When you train your quads, drop sets don’t make the outer thigh muscle grow more than regular sets — both methods make it grow about the same.

Both drop sets and regular weightlifting make your muscles bigger — and both work pretty well, even if you're just starting out.

All the research so far is on young, experienced male lifters — we don’t know if drop sets work the same for women, older people, or beginners.
