Do our arms shorten when we get older

Edit Post

The question might be stupid, I don't think our arms get "shortened" while aging. But, I realised that there are very brilliant people in the forum who knows a lot about biology, not only related to LL. So I felt the need of asking it to the forum.

The reason I'm asking it is that I think Arnold Schwarzenegger's arms look short for his body on this video:

As a peak 1.88cm guy on his prime, he shouldn't have had such short arms though. Now he shrunk to 180cm. But still, he has short/below average arms I guess.
What do you all think?

That's what exactly I thought. Excellent answer.

BodyBuilder, I was talking about Arnold's forearm in that video. It literally looks as long as my forearm which I think I have tiny forearms. And his height at peak was taller than mine about 6 inches.

Check the link in the first post. In the video they look short, without any muscle mass as much as the pics u sent.

Edit: I just realised, the reddit video actually was posted by Arnold himself LOL!

ah yeah, now it looks like an inch taller than mine thanks

I'm also skinny, but I can definetely say that If my forearms were just an inch taller, I'd look good at 6'1. Now, I'll have "slightly short" arms If i get to do 2 LL.

Well, I want to be at least 180cm which thank god I can hit it with only one segment legnthening, but I'd never lengthen tibias up to 7 centimeters. I stand on my toes, looking at the mirror and I look like I'm on stilts so bad. I look tall due to my slim build. If I don't consider my tibias, only pay attention to my overall height while sitting on my toes, it's nearly excellent. So, I'd enjoy being 5'11 flat. But, If i lengthen my femurs, my tibias will be short so.. I HAVE TO do 2 segments.. Otherwise, 5'11 is a great height though.

Quote from: NotSoBigBadBruin on September 03, 2020, 08:54:33 PMI think disproportionately long tibias look much better than disproportionately long femurs, but that’s just my personal opinion. So I’d do either tibial lengthening only or both segments. Unfortunately, the risk of permanent knee pain is higher with tibial lengthening.

I think, on the femur lengthening, there are almost %0 risk of having a permanent knee pain. Since, in a manner of speaking, they put the nail through your butt (mostly). There's nothing to do with the knee.

Also I think disproportionally long tibias would cause less bio-mechanical problems than femurs. I cannot even thinking of running-walking properly with too much of a femur and a short tibia. That would be a disaster LOL!

But, I also think that long tibias look like you are on stilts now so, it depends on you tbh. If you have short tibias, ofc go for the tibs!
