Does anyone have any advice on the best way to get my boyfriend more interested in working out? He is stressed out at work and it runs him down. I try to encourage good eating habits with some success. I know he would benefit from the confidence that would come from building himself up and getting a little more muscle on his frame. He just seems to have no interest or motivation to do it. Has anyone had any success with this with their SO? Thanks!
