Easy!
I've done two rounds of P90X and it is a great program. It is time consuming though with each workout about an hour.
The original poster said that he doesn't want to give up "daddy" time in the evenings and is not one for getting up at 5 and going to the gym. Hard to make a commitment to working out with those restrictions. My first round I worked out after the kids went to bed but missed the time with my wife. My second round I got up at 5 and went down to my basement. It was hard at first but I found I had more energy in the evenings with the kids and the wife.
Beachbody fitness has some great workout programs: ChaLEAN Extreme is good and not quite as intense as P90X; Tony Horton One on One; 10 minute trainer; Slim in 6; and a new one coming out this month called "Insanity" (I did one of the workouts from a trial DVD and it was the hardest cardio workout I've ever done).
Yeah Tony Horton’s workouts are the real deal. I’ve never seen results so fast from anything else like his circuit training. I’m on about week 4 of restarting P90 and I feel great. Everything else just falls into place when you start working out.
