Thank you. And it absolutely is but given his field and current situation I figured it would be a a little easier to start.
1) Taking off his shirt is a pretty easy sell. He looks like an Olympic gymnast. It obviously doesn't mean he knows everything but he's achieved visible and noticeable results over time and that is likely to earn trust.
2) He was previously in the military and was always at the top in physical fitness tests. Again, it's a bit of a marketing edge over other people.
3) If necessary, he could undercut other personal trainers in the area. They're likely to have more expenses and a higher rate if it's their full-time gig whereas my brother would be doing it for some extra cash and as a resume builder while he's still in school.
However, I know what you mean when it comes to tech. You gave a fair piece of advice. I just went a slightly different route for him since I don't think his field has the same type of internship model built into it that can give techies more options.
