Core strength: Side star plank

The Core strength: Side star plank will improve the static strength of your side muscles and increase your lateral (side) stability. This will prevent you losing your balance when running, and means fewer injuries.

Technique:

• Lie on your right side and place your right elbow beneath your right shoulder, resting on your forearm.
• Raise your hips off the floor to form a straight line from your shoulder, through your hips to your feet.
• Lift your left leg up to form a five-pointed star.
• Hold the position.
• Lower and repeat on the other side.

Be safe:

If your lower knee hurts, pull your tummy in tighter.

Ensure you don’t roll your hips backwards.
