1 - Attach ankle straps to a low cable pulley and secure them around your ankles.
2 - Lie on your back facing away from the cable machine with your legs extended toward the pulley and your hands holding a stable support behind your head if available.
3 - Brace your core and lift your legs so your hips and knees are bent to about 90 degrees, keeping tension on the cable.
4 - Curl your pelvis off the floor by drawing your knees toward your chest, focusing on contracting your lower abdominals rather than swinging your legs.
5 - Pause briefly at the top with your hips lifted and your core fully engaged.
6 - Slowly lower your hips and legs back to the starting position under control while maintaining cable tension.
7 - Repeat for the desired number of repetitions without using momentum.
