All I can say is good luck I know its hard working outside. Here is a bit of inspiration.
When I was a teenager there was a guy that worked out in the ymca with all of us kids. He was pretty big, I am sure he was just a few years older. As we all got to know him we found out that he was a laborer at a construction site, his hands was like sandpaper. As the years went on he got bigger and bigger.
The same year that gaspari won some title in france this guy was going to beat gaspari but he did something stupid. He entered into france with gear in his briefcase and they threw him out of the country.
Later on Sergio olive met him and said that he had never ever seen a pair of legs on a human being like that before. Guys would go back to their countries and tell others that this guy was unbeatable.
I have since been trying to find him but I have no idea what country he is living in now.
I don't know what kind of work you are doing outside, but remember this guy was a laborer at a construction site. That is hard, hard, work.
