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.
