How to do X-Ups

Lay on your back with arms and legs extended outwards, forming an 'X' shape. Simultaneously lift all four limbs, crunching your body. Lower and repeat.

Common mistakes

Collapsing too quickly or not engaging the core muscles throughout. Using momentum instead of a controlled movement.

Breathing

Exhale as you lift and crunch; inhale as you lower back to the starting position.
