How to Sit-ups
1- Lie on your back with your feet on the floor and your knees bent. Place the tips of your fingers on either side of your head.
2- Engage your core muscles and raise your torso upward, leaving just your buttocks and feet on the floor. Drive the movement entirely with your core.
3- Pause at the edge of the movement, then slowly lower your upper body to the start position, controlling the movement with your core.
- Sit-ups exercise helps strengthen, tighten and shape core muscles. A strong core allows you to perform at higher levels during any sport or physical activity.
- It helps strengthen the diaphragm: Sit-ups exercise causes abdominal tension that can have a positive effect on your diaphragm. A strong, healthy diaphragm can improve your breathing patterns and increase athletic endurance. One study examined the effects of various abdominal exercises in terms of diaphragm pressure and observed that sit-ups are beneficial in strengthening the diaphragm and improving respiratory function.
