Unless you’re going for above-normal strength, extreme muscle definition or cardio fitness, this really is all you need to do.
Exercise science is a fine and intellectually fascinating thing. But sometimes you just want someone to lay out guidelines for how to put the newest fitness research into practice.
An article in the May-June issue of the American College of Sports Medicine’s Health & Fitness Journal does just that. In 12 exercises deploying only body weight, a chair and a wall, it fulfills the latest mandates for high-intensity effort, which essentially combines a long run and a visit to the weight room into about seven minutes of steady discomfort — all of it based on science.
“There’s very good evidence” that high-intensity interval training provides “many of the fitness benefits of prolonged endurance training but in much less time,” says Chris Jordan, the director of exercise physiology at the Human Performance Institute in Orlando, Fla., and co-author of the new article.
