Hold a medicine ball between both hands and stand tall with your back straight, shoulders relaxed, abs engaged, legs straight, and feet placed hip-width apart. Extend your arms straight overhead, holding the ball above your head.
INHALE: Keeping your upper arms close to the sides of your head, bend your elbows approximately 90 degrees to lower the ball toward your back. EXHALE: Slowly straighten the elbows to return to the starting position and complete one rep.
Keep your shoulders relaxed away from the ears at all times. Engage your abs and keep your back straight; try not to allow your lower back to arch. Think about stabilizing your upper arms (as if squeezing them to your ears) so that they don't move to better isolate the triceps.
