How to do it

- 1
Lie flat on your back with arms and legs spread out in an 'X' shape, holding a dumbbell in your right hand.

As you exhale, raise your right hand and left leg to meet above your torso, performing a crunch.
- 3
Inhale as you slowly lower back down to the starting position.
- 4
Repeat on the opposite side, alternating for the desired number of repetitions.
Expert tip
Keep your movements controlled and focus on using your abs to lift your torso and arm rather than relying on momentum.
