In this video, you will learn how to do a single-leg glute bridge with a Swiss ball.
1. Start flat on your back with one leg on the ball
2. Drive through your heel to raise your hips up until your body is in a straight line
3. Return to starting position
You can use your arms slightly for stability but try not to use them unless you need to. Be careful to not arch your low back at the top position. Since the Swiss ball can move, it increases the difficulty of the single-leg glute bridge.
However, if you want to increase the difficulty more, you can drive harder into the ball with your heel while performing the exercise. And, if you want to make it even harder, you can move the Swiss ball back and forth at the top position. Just make sure that you maintain your hip height while you do that.
