Doing leg exercises with both legs at the same time for 12 weeks makes you stronger at lifting with both legs together, while doing them one leg at a time makes you stronger at lifting with each leg separately.

Randomized Controlled Trial

Human

1996 Sep

People who trained both legs at once got stronger at doing that, and people who trained one leg at a time got stronger at that — and each group improved more in the way they trained, just like the claim says.

Similar Assertions

When people train one leg at a time, that leg gets much stronger than the other leg, even if the other leg didn’t do any training.

84%

Even people in their 50s and 70s can get much stronger and activate their muscles better after 12 weeks of heavy weight training — age doesn’t stop them from improving.

81%

Whether you train both legs together or one at a time, your thigh muscles grow about the same amount after 12 weeks of heavy lifting.

80%

Whether you lift light weights many times or heavy weights fewer times—both can make you stronger in exercises like squats and deadlifts, as long as you push to exhaustion.

80%

Lifting heavy weights for 10 weeks makes you stronger, no matter how long you rest between sets or how many reps you do, as long as you’re lifting around 80% of your max.
