This article: http://shine.yahoo.com/channel/health/slim-down-tone-up-quick-tips-that-really-work-477521/ is the reason I will always have clients coming in the door. As I have said in the past, whatever mode of exercise you choose to do, intensity is the key, not duration. If the body is not stressed outside of its comfort zone, it has no reason to adapt to the new stimulus. That being said, the fitness industry keeps pumping out bullshit like this article, doing bent rows with a 1 liter water bottle, and people believe they are going to change their shape following such crap advise.
