I am not a super healthy person - but I am not overweight. I go to the gym once in a while or do some push ups at home. My wife on the other hand is crazy fit! She goes to the gym 4 or 5 times a week and eats healthy too. But even she isn't into Crossfit.
I know that a lot of people have gym memberships and that there are a lot of options when you are actually at the gym. I also know that 'going to the gym' is not the same as 'working out'. I go to the gym. My wife actually works out.
