Sweat Science is about the science of exercise, fitness and training. What do researchers know about the best way to warm up, lose weight, or train for a triathlon? What remains unknown? We break down the latest research, discuss it and argue about it. We debunk common workout myths, and attack the shoddy science used to sell many fitness products. We demand evidence.

The blog started in February 2009 as an offshoot of the Jockology column that I write every second week in The Globe and Mail. I envisioned it as a place to continue some of the conversations started by those columns, and post tidbits that didn’t make it into the paper. Since then, the blog has grown to the point that the conversation goes both ways – questions and comments posted on the blog sometimes lead to further research that become articles in the newspaper, or in my Science of Running column in Canadian Running magazine (where I’m a senior editor).

Eventually, I decided to pull all this research together into a book that attempts to sum up what scientists know (and what they don’t know) about the most common fitness and training questions. Which Comes First, Cardio or Weights? Fitness Myths, Training Truths, and Other Surprising Discoveries from the Science of Exercise was published in May 2011 by McClelland & Stewart in Canada and HarperCollins in the United States. It’s been greeted with great reviews from publications covering the spectrum from fashion and lifestyle to hardcore fitness and training mags.

My personal website, www.alexhutchinson.net, has details about my past incarnations as a postdoctoral physicist and an elite distance runner, as well as articles of mine from Popular Mechanics (where I’m a contributing editor), the New York Times, Runner’s World and many other publications.
