How fast or slow you lift and lower weights probably doesn’t make much difference in building muscle—unless you’re doing something very specific, but we’re not sure what that is yet.

How fast or slow you lift and lower weights probably doesn’t make much difference in how much muscle you build—unless there’s some special situation we haven’t figured out yet.

How fast or slow you lift and lower weights probably doesn’t make much difference in how much muscle you build—but it might matter a little depending on whether you’re pushing down, pulling up, working a specific body part, or going all the way to exhaustion.

When people lift weights, changing how fast they lift or lower the weight, or whether they go all the way to exhaustion, doesn’t seem to make a big difference in muscle growth—any differences are tiny and not very clear.

Whether you lift weights slowly or quickly, you’re probably not going to build more muscle with one over the other — the difference is so tiny it doesn’t really matter in real life.
