Start in the same position as exercise #4, but straighten your legs with your toes pointed. Unilaterally, lift each leg to a 90 degree angle, press your leg out as far as it will go, return to the center, and lower. This exercise will be a four count move for each leg. Try doing this exercise for one minute. To make the exercise harder, lift both legs at the same time.
Try these exercises the next time you are in the office to keep your muscles working, and keep you feeling great about your butt and thighs. Don't feel shy about doing these exercises in front of your coworkers, either. Get others to join in with you!
