That's good to hear mate. At least you're past the stage of hobbling around on one leg. What do you do for cardio these days? You could use a stationary bike, a cross trainer, or even a cross country skiing machine if you can find one.

By the way if you're interested I have a great ebook by the guys that came out with the X-rep called 'Xtreme Lean', it has a lot of great stuff in it. I can send you a link if you'd like.
