Specifically, the volunteers warmed up for two minutes on stationary bicycles, then pedaled as hard as The final group was assigned to interval training, using the most abbreviated workout yet to have shown benefits. (The scientists plan to study women in subsequent experiments.) One group was asked to change nothing about their current, virtually nonexistent exerciseĪ second group began a typical endurance-workout routine, consisting of riding at a moderate pace on a stationary bicycle at the lab for 45 minutes, with a two-minute warm-up and three-minute cool down. Then the researchers randomly divided the men into three groups. The scientists also biopsied the men’s muscles to examine how well their muscles functioned at a cellular level. They began by recruiting 25 out-of-shape young men and measuring their current aerobic fitness and, as a marker of general health, their body’s ability to use insulin properly to regulate blood sugar levels. ![]() To date of super-short and more-standard workouts. So scientists at McMaster University in Hamilton, Ontario, who had themselves conducted many of those earlier studies of interval training, decided recently to mount probably the most scientifically rigorous comparison But because of time and fundingĬonstraints, most studies of interval training have had limits, such as not including a control group, being of short duration or studying only health or fitness results, not both.Ĭonsequently, fundamental questions have remained unanswered about just how well these very short, very intense workouts really stack up against traditional, endurance-style training. Previously, I have written about a number of different interval programs, involvingĪnywhere from 10 minutes of exhausting intervals in a single session to seven minutes, six, four and even fewer. Interval sessions can be short, making them a boon for anyone who feels that he or she never has enough time to exercise. ![]() followed by light exercise such as jogging or resting, then another sprint, more rest, and so on.Īthletes rely on intervals to improve their speed and power, but generally as part of a broader, weekly training program that also includes prolonged, less-intense workouts, such as long runs.īut in the past few years, exercise scientists and many of the rest of us have become intrigued by the idea of exercising exclusively with intervals, ditching long workouts altogether. I have been writing for some time about the potential benefits of high-intensity interval training, a type of workout that consists of an extremely draining but brief burst of exercise - essentially, a sprint Let me repeat that finding: One minute of arduous exercise was comparable in its physiological effects to 45 minutes of gentler sweating. In fact, 60 seconds of strenuous exertion proved to be as successful at improving health and fitness as three-quarters of an hour of moderate exercise. That’s it! Your timers will be automatically saved so that they are easily available for future visits.Think you’re too busy to work out? We have the workout for you.įor many of us, the most pressing question about exercise is: How little can I get away with? The answer, according to a sophisticated new study of interval training, may be very, very little. You can choose between an hour-based timer that ranges between 1-12 hours, a minute-based timer that ranges between 1-120 minutes, and a second-based timer that ranges between 1-90 seconds.Īfter you select the timer you want, then you will be taken back to enter your custom message and select your alarm tone. Simply click “Use different online timer” and you’ll be directed to a new page. If you need a timer set for a different amount of time than 1 minute, it is simple and quick to change the setting. You can choose between a tornado siren, newborn baby, sunny day, music box, bike horn, and simple beep. Then, choose the sound that you want the timer to make when the countdown is finished. For example, you could enter “Time for another 30 pushups!” If you want to enter a message for your timer, simply type it into the message box. You just set the timer and use it whenever you want. If you need to set a timer for 1 minute, then you are at the right place! This simple-to-use web app is free to use. ![]()
