How to do the Single Leg Extension Crunch
Begin by lying flat on your back on a comfortable surface, with your legs extended and your arms reaching over your head.
Engage your core and lift your upper body slightly off the ground to start in a crunch position with your hands joined together.
Bring one knee in towards your chest while simultaneously bringing your arms forward to meet your knee. The other leg should remain extended a few inches off the ground.
Extend the bent leg out to meet the other leg without resting it on the ground, keeping both legs off the ground throughout the move.
Return to the starting crunch position with your upper body slightly raised and arms overhead, legs extended, and feet lifted.
Alternate and repeat the movement with the opposite leg.
Remember to control your movements, focusing on engaging and contracting the abdominal muscles throughout the exercise. Avoid putting strain on your neck; keep your gaze upwards and chin slightly tucked. Breathe out while you crunch and bring your knee in, and breathe in as you return to the starting position.
