Thanks great! I've never been much of a runner and probably wouldn't want to start in my 50's because it can be hard on the knees. Some people love it though. I've heard it releases the endorphins like nothing else.
You're welcome! I discovered stair climbing while working in high rise office building. Co-workers and I used to take an afternoon break from our desks and climb for exercise.
Great to hear from you! I hope your year has been a good one so far.
