When you’re just starting out, how much total work you do matters more than how long you rest between sets—your muscles grow and get stronger either way.

Comparison between 20-s and 2-min inter-set rest intervals on changes in muscle cross-sectional area and maximum strength under volume-load-equated resistance training

Randomized Controlled Trial

Human

When untrained guys lifted weights with either short (20 sec) or long (2 min) breaks between sets—but did the same total amount of work—both groups got just as strong and built just as much muscle. So, how much you lift matters more than how long you rest.

Similar Assertions

Even if you rest only 20 seconds between sets instead of 2 minutes, as long as you do the same total number of reps and weight, your muscles still grow and get just as strong.

84%

The strength gains from this study are about what you’d expect from regular weight training—whether you rest a little or a lot—so rest time doesn’t seem to change how much stronger you get.

83%

If you take only 20 seconds between sets, you have to do way more sets to match the same total weight lifted as someone taking 2-minute breaks, making your workout longer and more intense.

83%

You don’t need long breaks between sets to get strong—just do the same total amount of work, even with short rests, and you’ll get just as strong.

82%

If you do the same total amount of weightlifting work, it doesn’t matter much if you rest 20 seconds or 2 minutes between sets—your muscles grow and get stronger about the same either way.
