what he is describing is a man who has physical properties that put him on this side of athletic and Paul's psychology matches the "aliveness" of his physical attributes.
The paragraph is divided into 3 parts.
1. his physical characteristics. How he moves, his height a hint at his weight
2. his psychology which is described in the middle as bubbly and spirited.
