Bend your knees, keeping your feet flat on the ground.
Place your hands either across your chest or behind your head.
Keep your elbows firmly out to the side if you prefer to put them behind your head, but be sure not to pull yourself up with your arms to strain your neck. Your head should stay straight in line with your body.
Focus on just using your stomach muscles for this exercise.
While breathing out, lift your upper body off the ground until your stomach muscles are completely tight then slowly lower down.
Inhale, then repeat until your abdominal muscles are too tired to continue.
