171cm is not short nor tall in Spain.
As i stated before, my height is like Vince Taylor.
I know some people(in Japan) who owns bigger arms than me with natural state.
Yes and look how much gear Vince took..
You are claiming arms the size of guys who outweight you by 20kg and are 2-3 inches taller.
A guy with average genetics on gear at 5'10 will be happy with 18 inch arms lean. You are claiming this natural , weighing less and shorter
