I'm sure I will sound like a total bitch with this question but here it goes. What's a subtle and nice way to encourage my fiance to start working out and possibly lose a little weight? FI has gained quite a bit of weight since we first started dating. When we first started dating he still worked out and didn't eat as much as he does now. I of course still love him regardless of his weight and all other superficial things like that. But I am genuinely concerned that this will become a slipperly slope and his health will suffer as a result of his weight. He's a bit overweight as of right now but not terribly bad. I've noticed that he isn't as strong as he used to be and his endurance for physical things is down as well. It's really important to me that we both try to be in good physical shape but I don't know how to motivate him to work out. And I of course don't want to tell him he needs to lose a little weight because the last thing I want to do is hurt his feelings. So my question is, how do I approach this topic in a sensitive way?
