15-Minute Full-Body Exercise-Ball Workout
Move 1: Triceps Dip
Sit on a workout bench (or a stable chair) with your hands placed on the edge, fingers pointing forward. Rest your calves and ankles on top of a firm ball. Straighten your arms to lift your hips off the bench. Bend your arms to lower your body, then straighten them to the starting position. Repeat 15 times.
