I simply answered the question with the best answer. Making excuses for why people can't do it isn't going to help. All that does is reinforce their doubt and lack of self confidence. People would be amazed what they can do if they just apply themselves. 2 years ago I never would have dreamed I could do what I do now. I weigh a lousy 150 lbs, I'm 5'7" and I've been a small, unathletic midget my whole life. I may never be some amazing specimen, but I'm happy with what I can now achieve and it's only getting better.
