Just go back to the basics and be presentable. Even at normal work, there will always be clients that we rather enjoy meeting. You want to be one of those clients.

I really encourage working out and exercise more, especially the young and mid age punters. You will naturally feel better, more confident, and it boosts your testosterone level. I mentioned this before, if you want, you can do a few reps on the glamour muscles (biceps, triceps, shoulder, and chest) before going to your session. It will make you look toned and very athletic.
