Walking outside is more helpful to maintain balance and mobility than walking on a treadmill or using exercise equipment emulating stairs. Seniors interested in lower impact cardio activities can ride a bicycle or elliptical machine. Cardio activities should be done four to six times a week for 30 to 60 minutes.
