Here at Fitness Newspaper we’ll be starting a regular series of exercise challenges.

The first challenge is the Starcrump – a great functional exercise that works your whole body and particularly targets your shoulders and core.

How to Perform a Starcrump…

1. Start in a plank-like position with your hands together and your feet together.

2. Jump your hands and feet apart simultaneously, coming into a ‘star’ position.

3. Jump your hands and feet back together simultaneously, returning to the plank position.

The Challenge…

- Perform as many Starcrumps as you can in 30s (or a minute if you’re really hardcore), and then post your score (or a video of yourself completing the challenge) in the comments section below!
