Should people over 40 use treadmills?
Is there a certain length of time that someone over 40 should be on a treadmill for?
It is recommended that adults get at least 150 minutes of moderate aerobic exercise or 75 minutes of vigorous aerobic exercise per week, so using a treadmill for 30-60 minutes a day, a few days a week, would be beneficial for someone over 40.
