I just caught the end of the Stallone opus "over the top" (why have there not been many other great films about arm wrestling?).  I came to a shuddering realisation that I must have been to see this in the cinema... I had a sudden vivid recall of a scene of Sly in his truck, driving along the freeway, exercising his wrestling arm with a sort of in-truck weight-training type thing.  Nice.  The soundtrack was pretty excellent MOR soft rock as well - wonder if you can get that on Ebay?

Also made me think of "Touch the Truck" for some reason.
