samir suffered the middle eastern weak point known as average arms (size wize),,i been talking about this problem couple times on getbig,,he didnt inject no seo thus couldnt have mustaf arm size,,
but his physiqe was complete symetric balanced and conditioned to the max for the era talked about..because he was aware of the arm problem,,,he could have had a lot bigger delts if aimed at it,,,like 99% of middle eastern origin bodybuilders his delts were a lot stronger than his arms
he brought the good out and kept the weak points unoticed,,smart and one of the best in his time
