Chin Ups

Stability through the low back, and lumbar spine allows for maintaining your posture throughout your swing, and allows a transfer of power from the lower body to the upper body and arms

Starting position:

Grip the overhead bar with both hands, shoulder width or narrower, underhand, palms facing your body.

Movement:

Start the pulling motion by retracting the shoulder blades, then continue to retract the shoulders as you pull the sternum up to the bar, maintain neutral spine and upright posture, and keep shoulders retracted throughout movement. Return to start position, arms fully extended before starting next rep.
