One legged bridge on Sun exercise is a great move to focus on strengthening your butt muscle groups. The reason it works so effectively is because you have to recruit extra muscle fibers in your butt to maintain your position on the stability ball.
How to do a One Legged Bridge:
Lay on the ground face up with your heels resting on a stability ball. Lift your butt off the ground while simultaneously rolling the ball toward you when you’re arched as far as you can lift one leg into the air. Hold this position as long as you can. Your knee will be straight and you can even point your toe toward the wall.
Muscle group worked:
the primary muscle group that this exercise strengthens is your glute.
Target Repetitions for Muscle Strength: 30-60 seconds
Why a One Legged Bridge works:
The reason this exercise tightens your butt so well is again because it recruits more muscle fibers to stabilize your body.
Tips: With any exercise that requires a great amount of balance it is important to maintain tremendous focus. It also helps to tie in the muscle that you are working even more than is required by the exercise. Try it with this move.
Important!: Breathe in and out slowly throughout this exercise.
