all i see big arms. he always reminds me of the spongebob episode wherin he had inflated arms. haha

His arms aren't that big, if you look at the pic, his arm is turned to the side, making it look bigger...it's the old "a 16 inch arm that is in shaped and detailed looks more impressive than a 20 inch arm that is not in shape and detailed" adage.
When Phil is compared to Kai, Jay and Wolf, his arms are smaller, or the same size, but they are better detailed.
