The side bridge is an advanced exercise, particularly if you do the move on the forearm (another option is to balance on the hand). Adding a hip lift really challenges the obliques, making this a great overall core exercise. You can modify by keeping one knee on the floor or by taking the feet wide instead of stacked on top of one another.
- Lie on your side balanced on the forearm and feet.
- The hips and feet should be stacked on top of one another.
- Holding the torso steady, slowly contract your abs and lower the hip toward the floor (you don't have to touch).
- Avoid sinking into the shoulder.
- Bring the hip back up and repeat for 1-3 sets of 10-16 reps on each side.
