How do you do a curl-up?

Answer 1

A curl-up, or a sit-up is a common and simple exercise that will help strengthen your abs. To properly do one, lie flat on your back. Then, place your feet on the floor (the whole bottom of your foot should be on the floor) and make your knees into a triangle by putting them into the air at a 140 degree angle. They are not completely in the air. To do one, sit up slowly without leading too much with your hands, make sure your legs and abs are doing all the work. Do not take your feet off the floor or change your position too much.
