I have to agree with Chris on this one. Weight is a very important issue. I can carry a bit more than 35#, but I am a pretty big guy, and work out regularly. I also have the added advantage of recently having lost quite a lot of weight. As of my last checkup I have dropped 40# and still going. So the extra loss of weight make is easier to carry those little exrtas I may need. Also, less weight on me means fewer calories I need to sustain myself. A nice little positive returns cycle.
