• Sit on the floor with a dumbbell in each hand. Bend your elbows slightly so your palms are facing the ceiling, and the weights are next to your hips. Lift your legs off the floor and balance on your bum with your knees bent.
• Lift both dumbbells up and bring them in front of your face. Hold here for five seconds. Then lower the weights slowly back to the starting position. This counts as one rep.
• Try to keep your torso and legs stable as you move through two sets of 12 to 15 repetitions.
