Correct these common exercise errors and you'll get bigger, stronger, and leaner—in much less time.
Not Using The Right Reps
You have to vary reps based on the exercise and what muscles you’re training. Upper-body pressing moves train fast-twitch muscle fibers, so they should mainly be done with lower reps (sets of six to eight). Your leg muscles are designed for endurance, so sets of 12 or more reps are appropriate.
