Grab the bar using an underhand grip at the width of your shoulders. Go down with stretched arms and a firm body core. Slightly bend your knees and keep your legs firm against your feet and apart at the width of your shoulders.
Do your movement from the position with arms stretched forward by bending at your elbows and by pulling your chest up to touch the bar (contracting your back muscles). Your elbows point backwards. Exhale while moving up and inhale while returning to the starting position.
Keep your body core firm throughout the exercise.
While going up do not shift your pelvis, keep it in a neutral position throughout the exercise.
Watch your head and keep it upright throughout the exercise.
In the starting position remember to keep your shoulders in a neutral, fixed position and do not shrug them forward.
Begin at a smaller inclination to reinforce the correct technique.
