Set-up: Begin by lying on your side with your forearm resting on the ground.
Movement: Bracing your core, press through your palm. Contracting your tricep, straighten your arm to raise your upper body off the floor. Return to the starting position under control.
Emphasis: If the movement is too difficult, start in the top position and focus on the contraction of your triceps. If it is too easy, the exercise may be carefully attempted with the hips and lower body off the floor as well.
