Bodymedia METS help

Options
I was very excited when I ordered my Bodymedia off of ebay. I was so excited to really get serious and drop the extra weight. I had just finished couch to 5K and ran my first race. I do martial arts 3 nights a week and I teach kickboxing. I also hike and ride a bike often and have a very active job.

The bodymedia device arrived the day after I tore my ACL *sigh*
