I did the X but I went through them all and picked the ones I really did enjoy doing and did those a bunch. Kenpo X was my favorite. Stretching X was awesome. AB RIPPER X WAS A #$E%R()%RUI$ but I did that one too. I can't remember all the ones I did but it was a lot of fun and challenging as hell!

Now I do long walks ( I get sun AND a good cardio after a few miles so win / win for me ) and I used the weight machines on the Navy Base for my upper body. My legs need no help but my core and arms are in need of some TLC.
