How to do it
SETS 4 REPS 6 EACH SIDE REST 30SEC
Lie on your back with one foot on the floor, pushing your hips up into the air – the ‘bridge’ position. Hold the dumbbell on the same side as your raised foot and press it straight up, then lower it under control. Complete all your reps on one side, switch feet and repeat the reps with the dumbbell in your other hand.
