Backward Crunch
Begin in a supine position with your shoulders and legs raised slightly off the ground
and arms extended along the sides. From
this position, flex your knees and hips while
simultaneously contracting abdominals to
bring your knees to meet your chest. Slowly
extend knees and hips to return to starting
position and repeat.
Plank
Form a triangle with hands
and elbows, placing your feet
slightly apart. Raise body up
and hold, forming a straight
line from shoulders through
to feet. To increase the difficulty of this, keep the body
stable and raise one leg upwards. To decrease the difficulty of this drop one knee at
a time to the ground to reduce
the weight of the plank.
