You will get a new body in 90 days; it just may not be the body of your dreams. Yet! The P90X Home Fitness Training System is set up to be of value to anyone at any level of fitness. And, if you are wondering if women can benefit from it, a picture is worth a thousand words. Just take a look at the top of the P90X web page and you will see a woman lifting weights beside the man. Yes, women can use the P90X training system and can expect to achieve results based on what they put into the workouts.
There would only be one word of caution needed. If you are extremely out of shape or overweight, it would be in your best interest to check with your doctor before going on any exercise regimen. While the P90X is able to help you build that leaner, ripped body of your dreams, you also want to make sure you are in condition to start working out.
