<human>: Could you distill the essence of the text into 1-3 sentences?

I am 5'3" and I weigh 123 lbs. My bf is 5'8" and 165 lbs. I think it's safe to say neither of us are really overweight. We go the gym twice or thrice in a week and try to eat healthy few days of the week. 

When I go to the gym, I end up biking for 45 mins for my entire workout. He on the other hand, runs two miles and does some lifting to build upper body muscles.

Now my point is I go the gym to get fit and tone myself. I do not want to lose any weight. If by toning myself, I lose weight, that's fine by me. But I'm not actively trying to lose any. My bf thinks for us to be healthier we need to lose 5-10 lbs. He keeps suggesting more strenuous exercises, but I am happy with my biking regimen. This has caused some tension between us as he has continuously brought up his opinion on the matter.

Should I think about changing my routine and diet to help us both lose 5-10 lbs even though I don't believe it's necessary?
<bot>: My boyfriend wants us to lose 5-10 lbs to be "healthier" but I think I am fine.
