I thought 20MPH was a bit quick untill I worked it out, flippin heck, your running an average of 29KPH in the 100 meters, that means that olympic runners are going about 35 odd!! I for some reason didn't think we got much over 10...lol

ops:
Guess your wanting to add some muscle?
I'd advise joining a gym, I can never find training at home very motivating, and getting a good routine, and a high protein diet. I'd say more but im in a rush!
Sure someone else will help or I will later on!
