Set-up: Start seated on the floor with your feet down, arms bent at your sides resting on your palms, with fingers pointed laterally.
Movement: Lift your butt off the ground by contracting your triceps and extending slightly at the elbow. Slowly move from side to side, focusing on contracting and stabilizing using your triceps.
Emphasis: If the movement is too difficult, stay seated and focus on the contraction of your triceps. Stay conservative with the amount of lateral motion.
