4 Seconds of Exercise


According to a new study, ‘a mere four seconds of intense intervals, repeated until they amount to about a minute of total exertion, lead to rapid and meaningful improvements in strength, fitness and general physical performance among middle-aged and older adults’ writes Gretchen Reynolds, New York Times Well Columnist.

Although the high-intensity interval training (HIIT) were based on “a type of specialized stationary bicycle” the results suggest that strenuous but super-abbreviated workouts can produce outsize benefits for our health and well-being, a timely message as we plan our New Year’s exercise resolutions, add Reynolds.
