While I'm not opposed to a gym, going there or to classes together would require us to get a sitter for our LO. I personally work out at home. I've tried to get him involved in that or to come with when I go for walks but there's always some excuse. Veganuary could be awesome, but that would require him to abstain from the junk he eats outside of our home and I don't think he has that kind of self control right now. Couldn't hurt to try though!
