A great way start your P90X journey is with a cleanse. There is little chance that your body has not been hammered by toxins for most of your adult life. If you want your body to perform as optimally as possible, you can do it a huge favor by helping it cleanse itself from all the indulgences you have enjoyed over the years. Smoke or second hand smoke, alcohol, caffeine, environmental toxins are all getting in your system. Then there is the food we consume. If you eat a lot of processed foods or animal products that are factory farmed, your body would certainly benefit from a cleanse. A excellent method of cleansing the body uses the nutrition shake called Shakeology as the foundation of the cleanse. Three to seven days of using the shakes twice a day followed by a large salad with some high quality protein. Continue your P90X journey using the shakeology once a day while eating a clean diets of mostly vegetables and high quality proteins.
