I'm not defending the shakeweight, realistically unless you go on a very strict/balanced diet and use it alongside other excercise forms which could possibly include lifting dumbells in any case you're not going to see results. What I was defending is the physics theory behind how it works. It's not like that isn't proven. It's almost similar to the one where if I lift a 25kg box at maximum arms reach to stack it in terms of what I lifted on my spine and the damage I could cause I may as well have lifted properly a 250kg box (the damage possible equating to lifting something 10x heavier) this is why manual handling is so important to be taught properly. However, I think that because of the physics behind it the Shakeweight could truly work, maybe not as effectively as they paint in that ad but it could work, the theory is sound enough. I used to pump some iron (desperately need to get myself new dumbells) but considering I don't get the time I'd like of a day for a full work out I could forsee if it worked even at just twice the effectiveness of a dumbells set the logic of such a piece of kit. Then again people like you are also the kind of people who say games like Your Shape Fitness Evolved on the Kinect sensor can't improve someone's health or fitness, from experience I can say that I did burn plenty of calories and lost weight demonstrating that game and the Kinect Sports games over the xmas period, a period when 90% of people tend to gain weight. All things can work just needs commitment to the cause.
As for your comments bout looking anything near the guy in the ad...hate to break it to ya people but he's a pro body builder, he probably eats around 4000 calories a day minimum most of it chicken or carbohydrates such as rice. He probably pisses pure Whey shakes and spends his entire life in a gym, can't remember when he last touched anything remotely bad for his health and at one stage has at the least considered using steroids to get his muscles. None of us unless we gave up having social lives outside of our local gym are likely to ever look like him or close to him. He was insanely muscled compared to guys I work with who literally do body build training on a religious scale.
