You can do back extensions. Most gyms have the equipment. If you not a subscription, you can simply do at home. You lie flat on the floor with your arms at your sides and lift the top your body a little iche on the ground. It's like reverse crunches. You can also do this with your arms straight and lift your right arm and left leg or arm left and right leg simultaneously. This exercise gives you a cross - he mixes.
