Crunch- There are many different ways to do abdominal crunches
. While lying on your back bend your knees with your feet up against a wall parallel to the floor. If necessary leave them planted on the ground until strength has improved to modify it. Cross your hands over your chest and raise your head and shoulders off of the ground in the direction of your abs. This should contract the abdominals. To isolate specific muscles you can hold the position at certain intervals of the crunch. To strengthen the transverse abdominals move opposite shoulders towards the opposite knee. To increase the difficulty raise knees in the air with knees bent at 90-degree angle. Keep raised while going through the entire motion of a crunch.
