How Long It Takes To Rebuild Muscle After a Gym Break

Muscle memory helps regain strength quickly after a gym break. Study shows gains return in half the downtime.

A 2024 study found that people who took a 10-week break from a strength-training routine maintained their muscle growth, strength, and vertical jump performance after resuming their routine.1

“Our results therefore suggest that trainees should not be too concerned about occasional short-term training breaks in their daily lives when it comes to lifelong strength training,” the authors wrote in the study.1 

To test how taking an exercise break after several months of resistance training affected maximum strength and muscle size, researchers from the University of Jyväskylä recruited 55 relatively healthy men and women aged 18 to 40.

Participants were randomly assigned to two groups: one that performed resistance training exercises like bicep curls, squats, and lunges twice a week for 20 weeks, and another that took a 10-week break halfway through.

They discovered that the hiatus group made similar progress because their strength and muscle size quickly returned to pre-break levels as soon as they started training again.1 

“During the first few weeks after the break, progress was very rapid, and after only five weeks of re-training, the pre-break level had already been reached,” Eeli Halonen, lead author of the study and a PhD student in the Faculty of Sport and Health Sciences, said in a statement.2
