People in those days had a very different attitude towards the human body and how it was to be used. They were a lot more active at work and in their recreation. We would have been considered pathologically sedentary. Sitting around all day and night staring at books? Never getting your heart rate up or sweating on a regular basis? Nobody lived like that. They didn’t have machines to do everything; they lived in their bodies to a much greater extent than you or I. So their attitude towards the human body was quite a bit different.
Things like wrestling, hunting, riding, archery and so on weren’t “glorification of the human body”. They were normal activities for men outside of the slave classes, and even within them to a great extent. Warriorship is only part of it.
