A classic move from gym class, the sit-up works the abs and hip flexors through a wide range of motion. When doing sit-ups, remember not to lace your hands behind your head, which can put too much pressure on your spine and neck. Instead, place your hands behind your ears with palms facing forward, or cross your arms over your chest, and make sure your feet are planted firmly on the floor. Here's how to do a sit-up.
- Lie on your back with bent knees and feet flat on the ground, and place your hands on opposite shoulders.
- Keeping your heels on the ground and your toes flat to the ground, engage your abdominal muscles, and gently lift your head first, followed by your shoulder blades, coming into a full-sit up position.
- Hold the position for a second, and with control, come slowly back do to lying on your back.
- This completes one full sit-up.
