Core Exercise 6: The Single Leg Bridge Exercise
The single leg bridge exercise is the next step after you've mastered the bridge exercise. This move is a great way to isolate and strengthen the glutes and hamstrings, but when you do this exercise correctly, you will also find that it is a very powerful core strengthener.
Start on your back, hands by your sides, knees bent and feet flat on the ground, directly under your knees.
Lift up into a bridge position, and tighten your core.
Slowly raise and extend one leg. Keep your pelvis raised and level, try not to let one side dip down.
Work up so that you can hold this position 20 to 30 seconds while maintaining control. Be sure to do both sides.
