CRUNCHES
First, lie flat on your back with your feet on the floor and your knees bent at 90 degrees. Next, place your feet a few inches apart on a bench with your toes turned inwards and touching. Next, rest your hands lightly on either side of your head and keep your elbows parallel to your body before pushing your back down flat into the floor to isolate your abdominal muscles.
Next, lift your shoulders off the ground by gently curling them forward. Keep pressing your lower back into the floor, and then raise your shoulders only four to six inches. After that, you should hold and squeeze your abs for one count, and then move back to the starting position smoothly.
