The Jockology column on the science of exercise and athletic performance has appeared every second week in the Globe and Mail since March 2008. It was initially guided by current Life section editor Kevin Siu, and is currently edited by Cliff Lee. I’ve been extremely lucky to have the help of Trish McAlaster, a talented graphic illustrator at the Globe who also has a phys ed degree and previous experience as a personal trainer, right from the start.
