- Group 1: Changed nothing about their routine; the continued to be couch potatoes and walking blobs.
- Group 2: They rode a stationary bike for 45 minutes, including a two-minute warm-up and three-minute cool down.
- Group 3: They did 10 minutes of interval training, consisting of sprints on a stationary bicycle (at 20 seconds a clip), only one minute of which involved strenuous activity.
- As noted by the Charlotte Observer:
The upshot of these results is that three months of concerted endurance or interval exercise can notably — and almost identically — improve someone’s fitness and health.
- Martin Gibala, a professor of kinesiology at McMaster University told the Observer:
“It depends on who you are and why you exercise. If you are an elite athlete, then obviously incorporating both endurance and interval training into an overall program maximizes performance. But if you are someone, like me, who just wants to boost health and fitness and you don’t have 45 minutes or an hour to work out, our data show that you can get big benefits from even a single minute of intense exercise.”
The takeaway? Skip the gym, go to happy hour, and set aside a solid minute for a hardcore sweat sesh later this week.
