REVERSE CRUNCH

Targets: Upper abs, upper back

Do: 3 sets of 8 reps

(a) Lie on your back and lift your legs, bending your knees to 90°. Keep your hands by your sides.

(b) Bracing your abs, pull your knees towards your chest to lift your hips off the floor. Pause at the top, then slowly reverse the move to come back down, letting one vertebra touch the mat at a time. Tap your toes lightly to the floor at the bottom – don’t rest your weight on them – before starting the next rep.
