How to do the Leg Extension Star Crunch
Start in a seated position with your knees bent and feet flat on the floor. Place your hands behind you on the floor for support, with fingers pointing away from the body.
Engage your core and lift your feet off the ground, bringing your knees towards your chest to enter the starting position.
In a controlled motion, simultaneously extend one leg out straight and reach the opposite arm towards the extended foot, creating a diagonal line with your body. Keep the other leg bent, with the foot raised off the ground.
Return to the starting position with your knees towards your chest and then perform the movement with the other arm and leg, extending and reaching to the opposite side.
Continue to alternate sides, performing the leg extension while crunching and reaching towards the extended foot.
Perform the desired number of repetitions or for a set amount of time, maintaining a steady pace and controlled movements throughout.
Ensure you maintain proper form to avoid strain on the lower back and to fully engage the core muscles. Include the Leg Extension Star Crunch as part of a core workout or full-body routine to improve core strength and stability.
