The Sit-up is a good exercise for general abdominal and hip flexor conditioning.
How To Do It
1 Lie down with your knees bent, heels flat on the floor.
2. Tighten your abdominal muscles by drawing in the belly button to the spine.
3. Lift your head, keeping your eyes on your knees while contracting your abdominal muscles.
4. From the floor, pull up your body as close to your legs as is comfortably possible.
5. Hold for a moment before lowering your torso to the ground in a controlled manner.
Online Personal Trainer Tips
1. Your bottom position should be slightly elevated from the floor, not quite flat.
2. Cross your arms on your chest, or clasp your hands on your chest, or, for added difficulty, touch your fingertips to the sides of your head or neck (not behind or grasping your head).
3. Keep your back neutral and relaxed.
4. Keep your feet flat on the floor.
5. Hold a medicine ball or dumbbell, aimed at the sky throughout the movement, for even more resistance.
