When you commit to a fitness program, you want to know it’s going to work. Obviously, effectiveness is one of the key selling points of any workout system. But understanding how a program works inside the human body can give you a greater knowledge base of why it is you are doing what you’re doing and why some programs work better than others.
P90X works inside the human body like many of the best athletic training programs. It works by sculpting muscle, burning fat, fine tuning your cardiovascular system, and helping you to simply get healthier and happier. But knowing that it does these things isn’t like knowing how it all happens.
Inside the human body, muscle is created through strength and resistance training. Everytime you do a weight workout or a P90X resistance workout your muscles experience tiny tears and trauma (that’s why you’re sore!). The human body and the miraculous machine that it is, goes to work on these tears, healing them. It’s in this healing process that you get stronger and your muscles eventually grow. By helping you to select the right levels of resistance along with the right recovery, P90X encourages muscle building inside the human body.
Fat is burned through a few different processes. First, your metabolism increases as the amount of muscle you carry increases. Muscle needs more fuel than fat to survive. In this way, P90X increases your metabolism (fat burning process) by increasing muscle mass. In addition, you can burn calories directly through cardio work. The P90X series has several high quality cardio workouts to help facilitate this burn.
Finally, the P90X program makes significant changes inside the human body by changing what it is you use for fuel. By eliminating highly processed, high fat, and unhealthy foods, you are giving your body the equivalent of premium fuel, helping it to run more efficiently and increasing the results you see from the P90X workouts.
The entire P90X system was created to help you achieve some pretty ambitious fitness goals. It can only do this with your cooperation and a solid, well rounded program. Strength training, cardio, and nutrition are brought together cohesively in this program to create a highly effective tool for weight loss, muscle building, and overall fitness. There’s nothing you need to add to this program but determination—no additional workouts or diet strategies—it’s all here.

For P90X to work, determination is key. This workout regimen is both physically and mentally demanding. However if you have the drive to succeed, you will love the end results. I lost about 23 pounds during the course of the cycle and loved my end results. Just implement a proper diet and you’ll be fine.
