look i know the title sounds stupid...but I dont really know how to be a normal human, so please help. i want to start working out, but i dont know what to do. I'm 6 foot, if thats relevant, and im well built but just kinda fat really (not obese). I have recently got a new bike and i rode it for the first time today - this was the most intense exercise i've done in years. i dont just want to lose fat though, i'd like to build muscle.

so my question is how do i actually do that?
