My fiancé does crossfit...they can be some strange people. I guess it depends on the gym. Some are very encouraging and people get along well. Others are back stabbing and very "cult" like and really just in it for money. She enjoys it and it helps stay healthy. Most of the different places she has gone seem to have lots of relationship issues but that can be true anyways. Character flaws. If you enjoy it then go for it. I remember when exercise was just exercise. No competition involved. I've never seen people that are so prideful in ripping the skin on their hands but different strokes I guess.
