Continuing with the core are 2 more excercises. First would be on a 45 degree roman chair with your body placed sideways lower your torso until you have a strtch on one side then contract that side and lift the torso up. These are called oblique crunches. For the side ab muscles. Swithc side and do the other side as well. The last core exercise is to lay prone on a roman chair and lower your torso until perpendicular to the floor contract the lower back and lgute and hamstring muscles and lift the torso until parallel to the floor. keep the knees slightly bent to take unwanted stress off the lower back. next will be talking about small muscle groups like biceps, triceps, and shoulders.
