Welcome to +50 Len, I say that to put in that I use this very forum to inspire and inform me and I am in the same boat you are. As everyone has had great advice just let them be a guide and ask questions as you feel you need. The range of levels of experience and the friendliness is your greatest asset in getting to a good sustainable fitness. Shoot me a P.M. if you get over to NW Florida or SE Alabama and we can surly do some spinning and compare notes.
