So in a late attempt to get in moderate shape for my ski trip out West in January I started doing the P90X routine yesterday. Today’s day two and I’m definitely feeling it. Essentially, it’s 90 straight days of 1-hour aerobic routines that works your body in different ways. There are intermittent week-long breaks here and there. Doubtless if I do 90 days of 1-hour workouts I’ll be in better shape. What makes a difference is that you can do it at home at your convenience with a minimum amount of equipment and it is well-structured. That’s why its done over $400 M worth of business in 2010 alone. Pretty staggering. It’s a bit trying with school and work being at their peak busy-nesses right now, so the “X” in “P90X” may ultimately represent the fraction of the 90 days that I actually follow the routine, rather than “eXtreme” (everybody follow that?).
