Abs require more work, you need to tighten your diet as well, which is much harder then exercising for most people. You can have reasonable arms whilst still carrying some extra weight, abs you can't. And many guys like working arms as they are visible more of the time. You can't walk around with your abs showing most of the time.
I'm 45 and most of the early morning workout guys at my gym are 30-60. There's plenty with reasonable biceps, but those with abs (not that I'm particularly looking in the change rooms, but over 6 years at my gym you can't avoid seeing other blokes. Thankfully it's only when around 70 they for some reason feel it's fine to walk around with nothing on for an extended time) are few and far between.
FWIW from various on line articles / survey's of what's women's favourite men's body parts are (usual disclaimer everyone has their own preference), its:
1. Abs
2. Glutes
3. Biceps
Glutes sit somewhere in between for how hard to get a reasonable shape. From my own experience I've never noticed anyone checking my arms out or having commented to my wife on them, that she's passed on. I don't go out in public (outside the beach) with my abs showing (they sit a bit better than the visible shot above, but no where near the bottom ripped photo), so no comments there. By genetics I had a flat butt (like a straight line from shoulders to feet) until I did a bulging disc in my back and started working my glutes a lot to stop my lower back t aking over. Since then they gained shape and I've had her pass on to me that two of her friends have commented on my behind since then
They are Female and I like being married, so can't do that

How good are Aldi ice creams though?!Since putting mirrors opposite each other in my dressing room i see everything. Plus i went through a bad stage of eating lots of aldi icecream and uber eats.
I kept thinking i was accidently washing my clothes on the hot cycle and they were all shrinking. I kept ignoring all the signs telling me i had put on fat, like an ostrich putting its head in the sand.
Anyway it is now about the journey back to fitness and feeling good
Am getting enjoyment out of the gym for the first time in my life. I love weight training and have already asked to be reassessed because my routine is too easy.
It’s ok when she wants sexIsn't it going to the gym to get a body that she wants more of that?
It’s great when people notice you’ve bulked up
Same here!
True, the only people who can get away with that are those taking lots of drugs or (for a short while) guys doing a dirty bulk. However given for most who use gym as 'an offset' they'd not cut back at all if they weren't going, they are at least partially offsetting the excesses. Plus they still get to gain strength, get stronger bones, a fitter heart and the other benefits of the gym, even if not in full.
