Try this exercise. Begin by holding a kettle bell in each of your hands. Keep your abs tight and place your upper back on a balance board. Press against the floor with your feet in order to lift your legs and glutes from the ground. Now lift the weights up over your chest until your arms are straight. Bend your elbows and bring the weights down to meet your shoulders and then lift them again. Repeat for 2 sets of 12.
