Today was my P90X morning. This program was designed by Tony Horton. He has a whole P90X set which consists of 12 DVDs, a nutritional plan, a fitness guide, and additional items. If you feel you need all this to get you motivated to reach your goals- go for it! If you want to give it a test drive, purchase the Cardio DVD which is a mix of yoga, kenpo (boxing), and plyometrics (lots of intense jumping!). I bought this DVD on ebay along with the Kenpo and the Plyometrics all for around $25. It has been a great alternative to varying my workouts, and it also has been a good option during cold days!
