I'm amazed at the difference losing 5 lb. makes! I was 165 for the past two years, but got it down to 160 now and I can climb so much better! So yes, bigbadwulf, I guess 15 lb. would be a huge difference!
My goal is 155, which is what I was all through my 20's - 40's, i.e. before I got really old and started adding on the weight for no good reason.
