How to do the Seated 8-Leg Crunch
Start by sitting on the floor with your torso leaning slightly backward, and your legs extended in front of you. Place your hands behind you to provide support and balance.
Bend your knees and lean your torso back a little further, engaging your abdominal muscles to help balance your body.
Bring your knees toward your chest while simultaneously crunching your upper body slightly forward, making sure to exhale as you perform the crunch. It's important to engage your core throughout the move.
Now, add a twist to the motion. As you bring your knees in, twist your torso to one side. This will engage your oblique muscles.
Return to the starting position with your legs extended and torso slightly reclined. Remember to maintain tension in your abs and keep your movements controlled.
Repeat the movement, this time twisting your torso to the opposite side as you crunch. This completes one repetition.
Tips:
Keep your movements smooth and avoid using momentum.
Focus on using your core muscles to perform the crunch rather than pulling with your arms or neck.
Adjust the difficulty by changing the angle of your torso or the speed of the movement. The further back you lean, the harder your core has to work.
Remember to breathe steadily throughout the exercise. Exhale during the crunch, inhale when returning to the starting position.
Keep your neck relaxed and in line with your spine to prevent strain.
