Tracy Anderson's Green Juice Recipe - Help Proportions!?

i'm not sure what green juice is, but I've made many green smoothies lately. Basically, use a liquid like milk, soymilk, juice, or water, or anything you can think of. About 1 cup of liquid. Then add fruits and leafy greens. You can also add lemon, flax seeds, green powder, sweetener. Lastly, you could add some frozen fruits if you have them for texture.
