I sure will. A few people at my work have done it and I can see thier results so we shall see!

I did it last year, it is a lot of work and you need to be dedicated, but it definitely works.  I lost about 30lbs in 90 days.

I did P90X for 45 days at the end of 2010 before an injury (unrelated to the program) forced me to stop.  I have nothing but good things to say about the workouts*.  It's an incredibly varied well balanced program, very intense, and with amazing results if you're dedicated to it.  For me, it was just to improve my basketball performance, and it did that, as I was faster and stronger with better muscular and cardiovascular endurance than ever before.

*The diet portion of the program is another matter.  I'm an avid studier of nutrition, and my diet tends to be paleo like (only meats/eggs/nuts/fish/vegetables/nuts/seeds and nothing else).  I therefore disagree with a lot of the diet recommendations, especially foods containing unfermented soy for instance.

I didn't take their synthetic supplements either, and instead opted for Mercola Whole Food Multivitamins as well as his Whey Protein.

Finally, regular free weights are better than the bands, no matter what they say.

Let me know if you have any specific questions.  Incidentally, I'm currently on Day 65 of Power 90 - the earlier Tony Horton program that is a little easier - doing this one so my girlfriend can do it with me.

I did half a day of it, twice, haha.  It's pretty challenging.  I'm kind of an intense person and can't really pace myself though; I do as many reps as possible every set.

Agreed.  I got about 30 days into it and just didn't have the time to continue it.  It does work though, it's a good work out.  The yoga was a killer.

i have a friend that did it and it worked.  he got shredded and ripped. he said it is tough mentally as much as it is physicaly due to the dedication and investment.

i just ordered rushfit (GSP's program).  i am already in really good shape from doing martial arts 4 or 5 days a week, but wanted to try it out.

Well I will be doing it with the bands for now don't have the funds to get free weights at the time. But thanks for all the info. Keep it coming everyone!

One thing to consider is to check garage sales and stores that sell used weights. You don't need a lot for this. Free weights will give you greater results.
