Side plank
Hold your body straight on one forearm, side on to the floor.

How to do it
- Lie on your side with your elbow under your shoulder and your legs stacked.
- Lift your hips so your body is straight from head to feet.
- Rest your top hand on your hip, and look straight ahead.
- Hold, then switch sides.
Common mistakes
- Hips sagging towards the floor. Keep pushing them up.
- Elbow not under the shoulder, which strains it. Line them up.
- Rolling forwards or backwards. Keep your hips and shoulders stacked.
