How to execute Straight-Leg Sit-Up
The straight-leg sit-up is a great exercise for strengthening and toning the rectus abdominis muscle and core muscles. It can be done anywhere with minimal equipment and is a great way to improve stability and strength.
- To perform the straight-leg sit-up, start by lying on your back on the floor with your legs extended in front of you and your hands behind your head or crossed over your chest.
- From this position, engage your core and curl your torso up towards your knees. Make sure to keep your legs straight and your chin tucked in.
- Pause for a moment at the top, then slowly lower your torso back to the starting position.
- Repeat the movement for the desired number of repetitions.
To make the exercise more challenging, you can hold a weight plate on your chest as you perform the exercise. You can also increase the number of repetitions you do or the speed at which you do them.
