Curious....are Power 90 and P90X one in the same or different?
My brother is doing P90X and says the videos mean business, but are totally worth it. Most average about an hour and the results are impressive.
They are from the same company. Power 90 would be the one you would like to start with. It would be the step up to the P90X. They both are very good. Do not get P90X until you are ready. It also last about an hour. Power 90 ranges from 30 min. to 45. When I mentioned 20 minutes I was talking about a few other videos that I have depending on my time. I have hundreds and have found for me that is the way to go. I get a complete body workout in a short time. Just push play and do the video.
If you really want to transform your body, get Power 90 and follow the instruction right down to taking the before, 45 day and after pics. Your before and after pics will shock you. I would post mine if my before was not so embarrassing. BTW, the food choices are as critical as the workout. Good Luck!
