How to do the Quarter Sit-Up
Begin by lying on your back on the floor or a mat with your legs stretched out straight and your arms by your sides.
Engage your abdominal muscles by pulling your belly button towards your spine.
Slightly tuck your chin to your chest to maintain a neutral neck position.
Slowly lift your head, neck, and shoulder blades off the floor. The lift should be small, going up only about a quarter of the way to a full sit-up.
Pause at the top of the movement for a moment, keeping tension in the abdominal muscles.
Gently lower yourself back down to the starting position.
Repeat for the desired number of repetitions.
Ensure you breathe out as you lift your upper body and breathe in as you lower back down. The focus is on controlled movement to maximize the engagement of the abdominal muscles without relying on momentum.
