An 11-Minute Body-Weight Workout With Proven Fitness Benefits
******************
Five minutes of burpees, jump squats and other calisthenics, alternating with rest, improved aerobic endurance in out-of-shape men and women.
Five minutes of burpees, jump squats and other calisthenics significantly improve aerobic endurance, according to one of the first randomized, controlled trials to test the effects of brief body-weight workouts. The study’s findings are predictable but reassuring, at a time when many of us are relying on short exercise sessions in our homes to gain or retain our fitness. They provide scientific assurance that these simple workouts will work, physiologically, and our burpees will not be in vain.
Last year, when the pandemic curtailed traditional gym hours and left many people hesitant to exercise outside on crowded sidewalks or paths, quite a few of us moved our workouts indoors, into our living rooms or basements, altering how we exercise. Some of us purchased stationary bicycles and started intense spin classes or turned to online personal trainers and yoga classes. But many of us started practicing some version of a body-weight routine, using calisthenics and other simple strength-training exercises that rely on our body weight to provide resistance.
Body-weight training has been a staple of exercise since almost time immemorial, of course. Usually organized as multiple, familiar calisthenics performed one after another, this type of exercise has gone by various names, from Swedish Exercises a century ago to the Royal Canadian Air Force’s Five Basic Exercises (5BX) program in the 1960s, to today’s Scientific 7-Minute Workout and its variations.
