Sit Up

Sit-ups are a simple exercise that can strengthen your abdominal muscles and improve your posture. Here is an ultra short step by step guide for sit-ups:

1. Lie on your back with your knees bent and your feet flat on the floor. Place your hands behind your head or cross them over your chest.
2. Engage your core and lift your upper body off the floor until your elbows touch your knees or your chest touches your thighs. Keep your lower back pressed against the floor and avoid pulling on your neck.
3. Slowly lower your upper body back to the starting position. Repeat as many times as you can without losing form.
4. Repeat for the desired number of reps.
