Elevating your feet above your knees is beneficial for a couple of reasons. First, it increases blood circulation and prevents the development of varicose veins. And it gives you the perfect chance to lay back and relax. So make sure you kick your feet up at least once a day. Better yet, you can tighten your abs and promote good foot and leg health all at once with this easy crunch!
Step 1: Sit on the ball about 2 feet away from a wall, hands behind your head. Walk your feet out, and place them against the wall.
Step 2: Breathe slowly as you crunch up through a count of 10 seconds, using only your abs.
Step 3: Hold and squeeze for 2 seconds at the maximum tension point.
Step 4: Then return to the starting point through a count of 10 seconds.
Step 5: Repeat three times without resting. (Keep in mind that the range of motion is significantly shorter on this exercise, so be sure to adjust your pace.)
