No matter what anyone says, this is what it all comes down to - how you eat. I'm sick of seeing all the commercials about different workout programs and machines and blah blah blah where they show people who are ALREADY in shape doin moderate exercises like "do you want tight abs?" then go to the testimonial where the person is like "it's great!" with the "results not typical. individuals worked and maintained a steady diet" disclaimer in size 0 font. Then when people get the machines and realize this shit is fuckin hard work they get discouraged. When they don't see results after just 30 days they get more discouraged, and finally, when they don't see any results period they give up. Why? Because the programs don't emphasize that EATING RIGHT is the ONLY way to realize true gains during a workout. You can't do 20 minutes of p90x and then eat half a pizza, a burger, drink 2 sodas and have a bag of chips and think you're gonna see any results. Shit takes dedictation and the willpower to not just "go on a diet" or "lose a few pounds", but to actually change your whole lifestyle - i.e. everything about the way you're living - in order to truly live a healthy and well life where you will see losses and results in the time alotted if you stick to your goals. I swear there should be required reading with each program that says "THIS WON'T FUCKIN WORK IF YOU DON'T PUT DOWN THE BURGER AND EAT RIGHT!". Anyway, that's my rant.
