Yep. Downloaded them and will read them off tonight. Had the opportunity to buy a whole load of other docs and access to the web site for advice, etc., so you could end up spending more if you're tempted to. But since I've worked out in the past with trainers, etc. I think I'll be ok. The daily emails seem to be a part of the "plan" which costs a further $29.95 per month after a 21-day period, but I just wanted the basic program. I got 4 books, including the MAX workout, Lean Body Diet, guide to Bodyweight Workouts, and Muscle Recovery.
It's more the ankles/feet than the knee. Known plantar fasciitis in one and a recent sprain in the other, but general poor circulation because I am well unfit. Been to GP and got blood tests to make sure it's nothing other than being unfit, so ready to go for it once these lovely children are back in school and get back to myself.
I'm really excited ;)
