How to Side Plank
Side Plank muscles worked: Core
Form
- 1. Lie on your side and position your elbow under your shoulder.
- 2. Keep your legs together and engage your core and glutes to create a straight line from your head to your legs when viewed from above.
- 3. Maintain tension in your core for the given time and repeat the same on the opposite side.
Coach's Comment
- 1. When doing a side plank, make sure your body forms a straight line from your head to your toes, so that your lower back does not sag and your hips do not drop.
- 2. If you feel pain in the front of your shoulder or in your lower back, try lowering the difficulty by placing your knees on the floor.
