Ya, I'm going to save the money and walk at easy intervals until I'm comfortable. Thanks FF503. Before we went combination a few years back I was 903. You know how it is though. We might sound like a lot but it's not your typical, "have to cut the wall of the house" to get us out kinda big. I did 3 push-ups today with my pack loaded to 85lbs???? I don't think that's bad. My cardio is no where near where I want it yet, but time is of no concern for me. Just finishing. BTW, I'm dense too-----In the head
