Key Exercise Tip: This exercise assumes that you can do at least 25 stiff leg sit ups without any neck or back pain.
Keep your arms straight, your posture upright, and your shoulders relaxed. If you cannot relax your shoulders, the weight may be too heavy. Begin by pressing your but into the floor while lifting your upper body. Complete all of your repetitions on one side before beginning again on the other side.
Try it now: Complete 15 repetitions on each side (2-3 sets) as part of your workout routine.
