Build Quality Quads

Push from your toes when you do leg presses. Your quadriceps will work harder.

Avoid Burnout

To see if you're overtraining, check your pulse first thing in the morning the day after a workout. If it's 10 beats per minute or more above normal, your body is still recovering.

Skip Tendinitis

Use a shoulder-width grip when doing upright rows. Unlike the traditional narrow grip, it'll help you avoid shoulder-impingement syndrome—an injury that causes tendinitis and bursitis.
