Four-minute bursts of high-intensity exercise such as running on a treadmill, three times a week are enough to increase fitness, researchers found.

Three times a week for 10 weeks, the men undertook bouts of "vigorous" exercise, which involved running on a treadmill at a speed which raised their heart rate to 90 per cent of its maximum capacity.

... the exercises could easily be incorporated into a daily regime, for example by walking quickly up six to ten flights of stairs or by walking up a hill with an eight to 10 per cent gradient.
