Leg Cramps

I've been hitting the treadmill and Wii lately. I really want to get back to working out with my PT, but we are trying to figure out what we can and can't afford right now. For now, hiring my PT is on hold...hopefully by March I can be back to those awesome workouts! Anyways, in the mean time I have been trying to hit the treadmill or Wii Fit for a workout each day. I decided last Wednesday to try out the running program on the Wii...I got the WORST leg cramps. I'm talking the kind that you wake up with your muscles tensing...it was unbearable, and the worst part is that they lasted until this morning. I am finally feeling up for running after 4 days of recovery. I can't keep this up!
