Hamstring Bridge on Ball
Lie flat on your back with your heels hip-distance apart on the top center of a stability ball, knees and hips bent about 90 degrees, feet flexed, and arms at your sides.
EXHALE: Keeping back straight, arms down for balance, and abs engaged, slowly bridge hips up off the floor, aiming for a straight line from your shoulder to your hip to your knee.
INHALE: With control, slowly lower hips back down to the mat.
The ball will want to roll around during this exercise. The challenge and goal is to keep it is still as possible, using muscle control and core strength. Only bridge up as high as you can comfortably balance on the ball, working your way up to a full range of motion as you get stronger.
Muscles Worked: Glutes, Hamstrings
