We don’t know if drop sets work the same way for women, older people, or people who’ve never lifted weights — all the studies were on young men.

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.

It’s not clear if drop sets work better for people who already lift weights versus beginners — the study had too few participants in each group to tell.

We only know how drop sets affect the arms and thighs — we don’t know if they work the same way on your back, chest, or calves.

Doing drop sets (lifting heavy, then lighter weights without rest) builds strength just as well as doing regular sets with the same total weight, at least in young men who already lift weights.

Even though drop sets sound like they should make muscles grow more by keeping them under stress longer, they don’t actually make you bigger than regular workouts.
