I work out 2- 3 hours a day six days a week, doing alot more than walking on a treadmill. See my log "performance is not enough" I have gone from 200+ with 21% to 183 with 11% and i am preparing for an ironman!
Am I bragging- YEP! just like you. I put in the sweat ad th time, and I put other stuff aside. It is called sacrifice (if you see it that way).
Keep up the great work.
