i'm a 73 yr. old female who lives in az. where there are mountains to hike or concrete trails to walk on. since our health club is closed, hubby and i walk every morning; then we come home and do exercises either for beginners to hard cores, and there are cardio workouts or workouts with weights; our favorite is called has fit on youtube. we need to stay as healthy as we can during these difficult times; exercise also helps our mental health!
