The Jackknife Sit-Up is a challenging ab exercise that targets the core muscles, specifically the rectus abdominis and obliques.
How to perform
To perform a Jackknife Sit-Up, follow these steps:1. Lie flat on your back on a mat with your legs extended and arms straight above your head.
2. Engage your core and lift your legs and upper body at the same time, bringing your hands towards your feet.
3. Keep your legs and arms straight as you lift them, creating a V-shape with your body.
4. Slowly lower your legs and upper body back to the starting position.
5. Repeat for the desired number of reps.
It is important to maintain proper form throughout the exercise by keeping your back straight and your core engaged. Start with a few reps and gradually increase the number as you build strength and endurance.
