Similar to the pull-up, the chin-up is a powerful strength movement, requiring you to lift the weight of your body. The underhand grip activates your biceps, making the movement slightly easier than a pull-up. Try not to short-change yourself by swinging and using momentum.
Equipment
Pull-up bar
Primary muscle groups
Back, biceps

1 Jump up to grab the bar. Place your hands shoulder-width apart, palms facing towards you, and grip tightly. Straighten your arms and let your body hang. Raise your chest.
2 Use your back and biceps to pull your body up until your chin is above the bar. Pause, then lower your body with control to the starting position. That is one rep. Repeat for the number of reps given in your workout.
