Crab walk

Sit on the floor with your hands planted behind your back and your legs bent in front of you. Raise your hips upwards so only your hands and feet are planted on the floor. Start walking using your hands and feet to propel you forwards.

Top tip: Lifting yourself an inch from the floor won’t work anything other than your shoulders. Keep your hips as high as possible to ensure you work your core throughout the walk. Aim for 25 metres and try to ignore the funny looks in the gym.
