Sitting here switching channels between The Biggest Loser and a P90X2 Infomercial. So I have a few questions concerning the P90X program: Wondering who has tried P90X and your thoughts on the program? Did you stick with it for all 90 days? Was it easy to modify the program when needed? Did you see the huge results they show on TV? How did you work your tennis into the program and how did it affect your tennis game? Thanks. TripleB BTW: did a search and didn't see any info since last Summer.
