Striper, I hit mid 20's and pigged up deluxe. I was a skinny( sinewy)bastard until then. What ever exercise/activities you enjoy stick with them. I got married and stopped playing squash, cut down on martial arts,exercise overall, etc focused on career and making money. for the family. Uncle Buf says one thing, it goes on easy and it's a bastard to get rid of. You don't want to end up being called a farkin big thing if you can avoid it early.
