1 - Attach TRX straps or rings to a secure anchor point at a height that allows you to hang with your feet off the ground.
2 - Lie on your back beneath the anchor point and place your feet through the foot cradles of the TRX straps or grip the handles of the rings with your feet.
3 - Extend your legs straight out in front of you, keeping your core braced and your lower back pressed toward the ground.
4 - Exhale and contract your core to draw your knees toward your chest, curling your hips off the ground in a controlled motion.
5 - Hold the contracted position for a brief moment, feeling the tension in your lower abs.
6 - Inhale and slowly lower your legs back to the starting position without letting your lower back arch excessively.
7 - Repeat for the desired number of repetitions, maintaining control throughout the movement.
