1
Lie on your back on a flat surface with knees bent and feet flat on the floor, positioned hip-width apart. Keep arms extended along your sides or crossed over your chest.
2
Engage your core by bracing your abdominal muscles. Ensure lower back maintains neutral position with minimal arch. Head remains in neutral alignment with spine.
3
Slowly lower both legs toward the floor by extending at the hip and knee joints, allowing the legs to straighten while maintaining core tension. Lower legs only as far as you can control without lower back arching excessively.
4
Contract the rectus abdominis and iliopsoas to lift and bring legs back up to starting position with controlled movement. Return to bent-knee position with feet near floor or raised position depending on difficulty.
