>>35210>He probably get that shit from gymcelling, not from rockclimbing.Forearms are actually relatively hard to get that big from gymceling. Same as your calves. Both those muscle groups are made for doing a lot of work over long periods, and you need to use them a lot under load for them to get big. That's why fat or formerly fat people have the biggest calves (carrying extra body weight all the time) and rock climbers or sailors or something like that have big forearms.
>Just look at the Tibetans who actually lived in the mountains and climb rocks everyday.Not the same thing as rock climbing. They are walking around, using their legs more. Some Tibetan monks or whatever do a bit of climbing but they are still mostly walking, not pulling themselves with their arms. If you mean people like sherpas they are walking carrying shit working their legs more than their arms. "Rock climbing" here is when you climb like a monkey on a rock face. You don't usually carry a lot of extra weight but your forearm muscles are supporting your body weight the whole time so they get a lot of work.
>One thing i noticed is that people who grow muscles due to their lifestyle or job rather than regular trainings have tight and compact ones instead of the very prominent bulges you see from bodybuildersBodybuilders specifically target muscle size (hypertrophy) and use steroids so they are going to beat anybody at size alone. Any form of training is going to make the muscles bigger though, and plenty will make the muscles noticeably big. However, most people live a sedentary lifestyle today, so someone with bigger muscles may not look bigger overall compared to the average person who has smaller muscles but more body fat. The lower body fat is a more noticeable difference on most fit people since you can't even see the muscles on your average couch potato to begin with.
