Day 36: Ab, chair knee tucks

Here's a new exercise from fitness guru Cindy Whitmarsh. In this exercise, you not only can work on sculpting your abs, but you can wake up your body!
 
Step 1: Sit at your desk and push your chair away from the desk so you have some room.
Step 2: Sit at the edge of your chair with your back super-straight.
Step 3: Bend your knees at 90 degree angles, with your toes pointed on the floor in front of you.
Step 4: Start the ab crunches by contracting your abs and leaning back slightly. This is your starting position.
Step 5: Alternate your knees, pulling into your chest and back down. Do one at a time. Squeeze your abs on each pull.
 
Do 20 crunches with each leg, take a quick break, and repeat for three sets of 20 crunches.
