How Slow Should You Go? A Systematic Review With Meta-Analysis of the Effect of Resistance Training Repetition Tempo on Muscle Hypertrophy

Systematic Review With Meta-Analysis

Human

This study found that lifting weights slowly or quickly makes almost no difference in muscle growth—so you don’t need to worry about going super slow to build more muscle.

Lifting weights fast or slow doesn’t really make a difference in how much your muscles grow — the tiny difference you might see is so small it probably doesn’t matter.

Lifting weights fast or slow doesn’t make much difference in how much your muscles grow — the extra gain from going slow is practically nothing.

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.

Whether you lift weights slowly or quickly, you’re likely to gain about the same amount of muscle — the speed doesn’t seem to make a big difference.
