Pull Up with Neutral Grip

Jump up and firmly grip the pull up bar with your palms facing away from you with a neutral grip.
 
Calmly allow your arms to straighten fully which will provide your Latissimus Dorsi with a pre-movement stretch.
 
Bend your legs to 90 degree angles and cross your ankles.
 
Pull yourself up to a point where your chin is above the chinning bar and arch your back at the top of the movement.
 
Reverse the movement and return to the starting position.
 
Keep tension in your shoulder muscles at the bottom of the movement to avoid injury to the shoulder joints.
