I bought P90X and the work outs are INSANE! It’s some of the most physically challenging work outs i’ve ever done and I’ve been in the Army and went through basic training so I think I’d know.
BUT. If you’re trying to loose weight, slim down, have a good physic and actually be able to see your abs. Then I have to tell you, no matter how much you work out. If you don’t change your diet you’ll never see the resaults your are looking for.
P90X comes with a diet guide and it’s a crucial part of the formula for changing your body.
