Ab Tuck
Ab Tuck — Sit on the floor with knees bent and lean slightly back while keeping your core engaged. Lift your feet off the ground and draw your knees toward your chest in a controlled motion, then extend them back out without touching the floor. Keep your spine neutral and movements smooth, avoiding momentum. This exercise targets the core and improves balance, stability, and overall abdominal strength.
