I've been in good shape to poor shape and back again various times in my life (fat kid, started wrestling, HWT state champion, competed nationally, stopped after high school, got out of shape, study abroad in Rio de Janeiro, got ripped, returned to the US, got out of shape again but not too bad, started working professionally, years passed still in okay shape but feeling my age, started randonneuring last year, started p90x3 3 months ago). All that said, of all the things I've done to work out and get in shape, nothing has impressed me as much as P90x3. The gains have been amazing for 3 months. It's easy to stick to, since it's only 30 minutes and you work out in your living room (you only need 2m by 2m of space). Equipment costs are like $200 to 300 (yoga mat, pull up bar, some elastic bands, some dumbells, push up stangs, decent cross-trainer shoes). Enough variety in the videos and the dialog is reasonably entertaining, even when watching the same episodes over and over again. As soon as you're done, you're able to shower in your own home. I work out every morning before work. I know I sound like a commercial right now, but this is a seriously well thought out exercise routine. Pretty much every one of the routines focus on core exercises and all do a great job of highlighting where you're weak and working those parts of your body. Once that part strengthens, the next time you do the same exercise, you'll find another part of your body that needs strengthening. They are always challenging and there's plenty of room to go from beginner and to growing and perfecting your form. Furthermore, many of the exercise work you out in a way that works out the areas that don't get attention as you age and these routines therefore resolve the things that make you feel old. You can just look at some of the people in the videos (including Tony himself) and tell that he and the others have figured out what you need to do to stay feeling young. Tony Horton is 56 and Dreya Webber is 53 and both look like they are in their early 40s. Traci Morrow is 43 and has had like 6 kids. For those people to look the way they do at their age is incredible. Learning to work out this way gives me more confidence in deciding to have kids later in life, knowing that I will still have the energy to be active with them as they are growing up. Between acquiring a bunch of home gym equipment and how easy it is to workout at home, I no longer see the appeal of a gym. When I want to work out outside I just go cycling and I might pick up another sport or two time permitting. The cost of most of the equipment is equivalent to 4-6 months of gym membership.
