Effect of different training frequencies on maximal strength performance and muscle hypertrophy in trained individuals—a within-subject design

Randomized Controlled Trial
Human
2022

The study found that doing the leg press once or three times a week for 9 weeks both made trained men stronger and built more quad muscle — so how often you do it doesn’t matter as long as you do the exercise long enough.

Similar Assertions

If you train your legs with the leg press machine for 9 weeks, you’ll get stronger and your thighs will get bigger—even if you do it just once a week or spread it out over three days.

Whether you use machines that change resistance as you lift or keep the same weight all the way through, after 20 weeks of training, healthy men gain about the same strength and muscle size either way.

If you only work out one leg with resistance training, that leg gets stronger, but the other leg doesn’t get stronger at all—even if you don’t train it.

If you're already strong and lift weights, training each muscle group either once or five times a week for eight weeks will give you about the same strength gains on the bench press, squat, and row.

If a guy does leg workouts with just one leg, three times a week for two months using heavy weights, that one leg gets noticeably bigger in muscle size—especially the fast-twitch fibers—while the other leg stays the same.
