Waiting to officially start metamorphosis

Ok so I'm getting a little sidetracked from Metamorphosis by Tracy, I did the cardio and my knees keep swelling and getting fluid on them, I believe its because I don't have good workout shoes. Tracy does recommend getting shoes with shocks in them because the cardio is basically all bouncing and jumping around. So I just ordered Nike Shox online and awaiting them in the mail to start. i will just continue to do Tracys method mat workout for now. Sunday is the start of my Detox clense I'll be keeping a daily record of that so stay tuned!
