Pull Your Body to The Up

Chin-ups involve the sternal portion of the pectoralis major, latissimus dorsi, teres major, posterior deltoid, the rhomboids, the middle and lower portions of the trapezius, and the elbow flexors. A wide variety of sports require strength in these muscles, particularly sports that require powerful upper body pulling action such as judo and wrestling.

Here's how to use your chin up bar. Install it so you can reach it standing with your feet on the floor and your arms extended over your head. To do the exercise, grasp the bar with your hands a little more than shoulder width apart using either an overhand or underhand grip, and pull yourself up slowly and smoothly until your chin is over the bar. Then lower yourself back down. Put your feet on the floor if you want to rest, or bend your knees and continue for multiple chin ups.
