Walking is a pretty fundamental human movement. Particularly for those who don’t want to jump, skip, run or tumble as their only methods of getting around. And while it certainly has its limitation as “exercise,” it can still be employed smartly to help you achieve your health and hotness goals.
In the world of fitness, there is room for disagreement and intelligent discourse among reasonable educated people. The human body is complicated and the reality is there is still a lot we don’t know about how the body responds to training and nutrition. I think the hallmarks of a good fitness professional are an aversion to dogma, a ravenous intellectual curiosity for continued education, and a genuine burning desire to provide the best service and information to their clients (and blog readers).
The fitness industry is a breeding ground for weird fads. Some come and go (usually the ones that suck, thank goodness) but some stay around and change the way we look at exercise.
