The New Walking Rx
If you spent decades putting fitness on the back burner, it’s not too late to lace up those sneakers and get moving now—and there’s a new reason to do just that. A study by researchers at McMaster University found that when a group of sedentary adults age 60 and older began a regular interval walking regimen, they showed significant improvements in both physical endurance and memory. Try it for yourself: Hop on a treadmill and start at an easy walking pace. Crank up the incline for four minutes, so your heart rate rises and you’re exerting more effort, then bring it back to level and walk easily for three minutes. Repeat three times. No gym? Find an outdoor hill and do the same thing.
