These days, you might be wondering what happens to our bodies when we take a break from training-and there's some good research on that topic. How long it takes to lose our strength gains and lean tissue size during "detraining" depends on several factors:

• how long you've been training

• your age

• your gender

• how intense your training was

The scientific data suggest that after a few weeks without training, we all start losing strength and lean muscle tissue. The longer the break, the more significant the loss becomes.
