2. Side Plank Crunch

Beginning on your right elbow and your foot slightly in front of your left, remember to keep your core nice and tight throughout.

Complete the exercise by pulling your right knee up towards your chest and proceed to crunch your left elbow towards it.

Finish by bringing it back out to the side plank position and repeat this in sets of three, around 10 to 12 times.
