Side Bridge

How to do it

1. Lie on your side with your legs stacked and your forearm on the floor directly under your shoulder.

2. Lift your hips off the floor so your body forms a straight line from head to heels. This will be your starting position.

3. Hold the position, breathing steadily, for the target time.

4. Lower your hips back to the floor and repeat on the other side.

5. Keep your hips stacked. Letting the top hip roll forward takes the work off your obliques.
