Thanks for your message. I am also one of the over fifties, and I want to start posting on your forum. If I try to walk outside, I begin to jog. I used to run 60 miles a week, and I even did the marathon. My doctor told me not to jog on concrete, but I do it sometimes anyway. I did read that step has half the impact of running, but sometimes, I can't stop myself from jumping on the step. I love the aerobic high so much, and it is so much better than any drug. I also had a very strange personal training session last night, but I will not elaborate. I have three AFAA certifications, and I know it is not as good as the College of Sports Medicine.
