How to do it
- Start on hands and knees with hands under shoulders and knees under hips.
- Brace your abs and keep your back flat.
- Extend your right arm forward and left leg back until both are level with your body.
- Pause, return and switch sides.
Common mistakes
- Rotating the hips. Keep them level as if balancing a cup.
- Arching the lower back. Reach long instead of lifting high.
- Rushing the reps. Move slowly.
Make it easier or harder
Easier: Extend just the arm or just the leg.
Harder: Pause for five seconds at the top or draw your elbow and knee together under your body.
Coaching tip
Reaching long is more important than lifting high.
