Three pilates exercises to work your core

Side-lying double leg lift

Lie on your side with legs stacked, head on bottom arm, top arm on the floor. Squeeze legs together and lift off the floor. Hold for a breath, then return to start. Do 10 reps and switch sides.

Reverse plank with leg raise

Sit with legs outstretched, hands behind your bum, fingers forward. Press up onto your hands and lift your right leg, keeping hips raised. Hold for 3 seconds. Repeat 5 times for each leg.
