When most people think of cardio, they think of long, boring jogs on the treadmill, or endless pedaling on the upright bike. But lately, the buzz in cardio training is high-intensity interval training (HIIT), which alternates between very high-intensity bouts of exercise with either a low-intensity bout of exercise or complete rest. This training style is a departure from the 30 to 60 minutes of continuous steady-state cardio that most people do on cardio machines.

If you watch sports on TV, at some point you’ve probably heard a commentator talk about an athlete having explosive or powerful muscles. For example, professional football player JJ Watt has received a lot of attention for his off-season conditioning program, which includes flipping a large truck tire. A sportscaster was recently discussing Watt’s training techniques and mentioned that Watt was working on his fast-twitch muscle fibers in an effort to become more explosive. At first this sounds kind of hokey—fast-twitch muscle fibers? Is that really a thing, and is it possible to do certain exercises that focus on one type of muscle fiber? The answers, in short, are yes and yes. Sunday, July 01 2018
