Vigorous workouts of as little as 30 seconds each can go a long way to reducing health risks from diabetes. The weekly amount of exercise should total seven minutes. Exercising 2 days each week, 4 times each day, 30 seconds per session, a group of out-of-shape but otherwise healthy individuals showed a 23 percent improvement in how effectively their bodies used insulin to clear blood sugar from the blood stream.
The tests were conducted by James Timmons, an exercise biologist at Heriot-Watt University in Edinburgh. While health is improved and other benefits are gained from more exercise, just seven minutes could make a difference for a great many people who are at risk for developing diabetes.
