TECHNIQUE: Start by lying on your back, and bending your knees with your feet together. Lift your feet off the ground so your knees are in the air similar to a crunch. Holding the dumbbell with both hands, use your core to lift your torso off the ground so that your butt is the only thing touching the ground. From here, twist your torso back and forth with the weight in your hands, while keeping your legs off the ground and as stable as possible. ADVANTAGES: This exercise one you can perform literally anywhere with or without a weight to strengthen the transversus and rectus abdominis. FAULTS: The main fault with this exercise is not rotating enough to touch the ground with either your hand or the weight. If so, you may need to scale down. SCALING: Scale this exercise by increasing the weight or reps. Scale down by removing the weight, interlocking your feet for more stabilization or keeping your feet on the ground as you perform the move.
