Whether you take short or long breaks between leg exercises, as long as you do the same total number of reps, your inner and outer thigh muscles grow about the same.

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

The study found that whether young men rested 20 seconds or 2 minutes between sets, their thigh muscles grew about the same amount—as long as they did the same total amount of work. So, rest time doesn’t matter much for muscle growth when the workout volume is the same.

Similar Assertions

If you lift heavy weights with either short or long breaks between sets—while doing the same total work—you’ll get about the same stronger in your leg muscles after 10 weeks.

When people who’ve never lifted weights before do leg exercises with either 20-second or 2-minute breaks between sets—while doing the same total amount of work—their thigh muscles grow about the same amount.

92%

If you take only 20 seconds between sets, you can still lift the same total weight as someone taking 2 minutes—you just have to do more sets to make up for the shorter breaks.

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.

84%

When doing intense leg exercises with 5-minute breaks between sets, people can do more total work than with only 2-minute breaks, because their muscles recover better.
