I get a large number of visits on this blog daily because of my experiences with the P90X work out program. And a few of these are from triathletes who are considering whether or not the program can help them with reach their multisport goals. I've tried to be as detailed as possible about my take on P90X and its benefits. For someone who doesn't have a lot of time and wants a strength program that is varied and well structured, I'd say it is well worth the investment of about $130 to $300 to assemble all the necessary equipment. If you want to know what I think about P90X then read the weekly posts. Sure you can look at the end result, but that won't give you the information you need about what it was like trying to do the program and maintain some semblance of triathlon specific work. That, in a nutshell, was hard. Very hard.
I've had quite a bit of time to consider to effects of P90X on Triathlon training having almost 2 years since I did my first workout pass. First I will say I do believe it is possible to do both P90X and Tri training. I've said that all along. But what I've also said is there are caveats. The main one being the results you are looking for from the program. If those results are more on the appearance side, then I'd definitely tone down the tri specific work until I "looked" the way I wanted.
On the other hand if you wanted to use P90X as a basis for enhancing tri performance, then I think with some modification to the routine it could be done with great success for all distances.
Why do I say this? I say this because many athletes tend to overlook the importance of basic strength in triathlon and focus an overly large amount of time on endurance. And when I speak of strength I'm talking about a concept beyond lifting weights in the gym a couple of hours a week in the midst of swimming, biking and running throughout the week. When I speak of strength, I'm speaking about things like range of motion, connective tissue, power, balance, coordination, muscular access, and muscular endurance.
The more I consider the way time is or can be spent preparing for Triathlon of any distance, the more I feel that each of the three sports are techniques to be learned and mastered, and the results you see on race day are from the successful integration and application of full bodied strength and technique work. P90X can certainly assist in creating that. You simply need to know when, where, and how to apply it in the scheme of your other tri specific training.
