Core strength: Superman plank

This static Core strength: Superman plank will strengthen your stomach muscles, which support you during uphill running. This is quite a tricky one to get right, as it requires you to concentrate on keeping good form in several parts of the body, particularly the shoulder blades, glutes and back.

Technique:

• Lie on your stomach and place your elbows directly beneath your shoulders.
• Lift your body off the floor to form a straight line between your shoulders and hips.
• Extend your right arm forwards until it is next to your ear.
• Raise your left leg off the floor.
• Ensure you keep your hips level.
• Repeat with the other leg.

 Be safe:

If you feel a strain in your lower back, raise your hips slightly higher.

Don’t lift your leg too high.

Focus on squeezing your shoulder blade towards your spine when raising your arm.
