One minute can be a good goal for a non-runner to achieve. When on a walk, set a timer on your phone and begin running when you hit the ‘start’ button. Run like you’re trying to catch something or someone. It’s OK if have a hard time making it the full minute. Just keep trying every day for one minute, and you will be able to do it. Then, you could try adding a second minute later in your walk or doubling your running time for a two-minute interval. A second minute, or even third, does seem to increase the benefit to your bone health. Plus, it burns a few more calories that can contribute to weight loss.
