Sit Ups Description

Step 1. Lie on your back with your knees bent and feet flat on the floor. Your hands may be across your chest or behind your head.

Step 2. Use your abdominal muscles to roll your spine up to a sitting position, keeping your feet flat on the floor.

Step 3. Then, without resting at the top of the movement, lower yourself back down to the starting position. Repeat.


The sit ups exercise is a combination ab exercise that works the upper and lower abs. The upper abs are worked during the first part of the motion, as the user pulls his shoulder blades off the mat. They are also engaged throughout the exercise. The lower abs are engaged during the second half of the exercise as they are what drives the upper body up to the top of the motion. It is important to keep the core tight throughout the entire motion. Relaxing the muscles at the bottom of the motion makes the exercise significantly less effective.
