Are sit-ups better than crunches?

Sit-ups involve a larger range of motion and engage the hip flexors, whereas crunches isolate the abdominal muscles more specifically. Both are effective, but sit-ups provide more functional core movement.

How can I stop my neck from hurting?

Focus on keeping your chin tucked slightly and avoid pulling your head forward with your hands. Imagine holding a tennis ball between your chin and chest to maintain proper alignment.

What if I cannot keep my feet on the ground?

You can tuck your feet under a heavy pair of dumbbells or a couch, or ask a partner to hold them. As your core strength improves, you will eventually be able to perform them unassisted.

How to Perform

Lie flat on your back on a mat with your knees bent and feet anchored firmly to the floor.
Place your fingertips lightly behind your ears or cross your arms over your chest to avoid pulling on your neck.
Exhale as you engage your core and slowly lift your upper body off the floor toward your knees.
Pause briefly at the top of the movement while maintaining a straight spine and keeping your chest open.
Inhale as you slowly lower your torso back down to the starting position with controlled motion.
Ensure your shoulder blades touch the floor before beginning the next repetition.

Common Mistakes

Pulling on the back of the neck with the hands
Using momentum or swinging the arms to sit up
Lifting the feet off the floor during the ascending phase
Rounding the lower back excessively instead of engaging the core
