Circuit 2, Exercise 5: Straight-Leg Bridge With Stability Ball
- Lie flat on your back and place the ball under your heels, with your knees slightly bent.
- Press heels firmly into the ball to raise your hips off the ground, coming into a bridge and actively squeezing your glutes as you lift.
- With control, slowly release your bum back down to the floor. This counts as one rep.
- Complete 15 reps.
