Today, just like any other day, I did P90X. Let me tell you something, P90X is serious business. There was a point when I thought it was just another lame DVD workout program that didn't really do anything besides help you lose a couple pounds. I couldn't have been more wrong about it. Not only is each workout extremely challenging, but the whole idea of "muscle confusion" actually makes sense.
A lot of fitness specialists can stand behind me in saying that repeating the same workout over and over will result in something commonly called "muscle memory", which means exactly that. Your muscles learn what you're doing to them, and instead of giving you big, strong muscle, they just sort of stay right where they are, making you feel no stronger each day. With Tony Horton's "muscle confusion" technique, the workout is mixed up right about the time your muscles start to get what's going on. Obvious changes in size and form can be expected in as little as three to four weeks.
Today I did "Shoulders and Arms" workout, which is as Horton says, your glamor muscles. Definitely not to be taken lightly, however. This program covers every muscle you can think of. Separate workouts cover all the way from your legs to your back and abs, and all the way to your chest, shoulders, and arms. It even involves a plyometric excersize, as well as cardiovascular, and even yoga and kenpo (which is extremely fun by the way).
If you feel like your lacking muscle, look no farther. Don't settle for any other weak DVD program when you can go extreme.
