According to new research, running (pretty fast but not too fast — from 3.5 to 5.5 miles per hour) or doing similar exercise for a single minute every day may lead to better bone health in women. Looking at data on more than 2,500 women who wore activity monitors, researchers found that those who did short bursts (one to two minutes) of weight-bearing, high-intensity exercise such as running daily had better bone health than those who did less than a minute. Women who did more than two minutes had even stronger bones. Now, this quick burst of exercise doesn’t replace the 30 minutes of moderate-intensity activity you need for overall health, weight management, and disease prevention. But adding it in is as simple as mixing in a quick run into your daily walk, playing tag with your kids or grandkids, or jumping rope for a minute or two.
"Brief bursts of intense exercise are remarkably effective." Martin Gibala, McMaster University
