What a difference having a smaller waist makes on the perception of leg size.
The weight that came off his midsection makes his legs look very large by comparison.
I thought about the pros who go for broke trying to gain size...end up with a big, bloated waistline and all it really accomplishes is making their legs looks smaller. In addition, whatever mass they gain is offset by the loss of aesthetics.
Please tell him that he looks much more handsome and to keep on eating clean. He'll look fantastic!
