Canadian Researchers State that a 20-Minute Twice Weekly Workout Keeps You Healthy

While many people struggle working out a couple of times a week, researchers from McMaster University, Hamilton, Canada, have come up with the exact number to get yourself healthy and stay that way. They basically wanted to find out with how little you could get away with, and still improve your health significantly.

They studied two groups of people, one was middle-aged and out of shape, the other was also middle-aged but had been diagnosed with some kind of cardiovascular disease. The patients were tested to determine how fit they were to start off with. The first group was out of shape, but generally healthy.

The patients tried interval training, which means that they had to integrate short periods of very intense exercise interspersed with cool-down periods on a stationary bike. The overall work out was very short. One minute of pedaling at 90% of their maximum, followed by one minute of easy pedaling. This was repeated ten times. This resulted in a 20 minute workout that was repeated twice a week.

The American Heart Association recommends 30 minutes of moderate-intensity exercise five times a week. However, this study indicates that it might not be necessary to spend that much time training or in the gym.

  1. Well being a 55 year old male I tried interval training, first session I managed 5x30seconds at high speed with 1 min at low speed, 4 weeks later I still can’t get to 1 minute at high speed and 1 minute at low speed, it is hard hard work and I am at the point of giving up

    • To Ronny: “High” and “low” are relative terms. Your high speed might be a teenager’s low speed. It doesn’t matter. It’s hard to measure “90% of maximum,” especially at home: but in my opinion there are general guidelines that can help to plan a long-term workout strategy:

      By the end of the high speed portion, you should be starting to lose your breath; by the end of the low speed portion, you should have your breath back. Adjust the speeds as needed. Don’t give up. 🙂
