P90X question for those who have tried the work out?

I have a above the knee amputation and was wondering in the P90X is a lot of solely leg work. I am pretty inventive to getting things done in ways I can, but is it a lot of kick boxing or something like that. I walk 3 miles a day and I am semi fit for my condition, but I would like to do more in house work out type stuff and I thought this would be fun. before I order though I want to know if its more geared towards leg work or what?? also did you see results and were you pleased with the system?
