That's wonderful that you have checked into doing internships... although right now you are a bit against that idea. I applaud the fact that you want to help these people, but I still feel that the internship would be a great opportunity! It's an obvious fact that a business has to look out for the bottom line... they have expenses that you don't. First, they have the overall expenses... payroll, self employment taxes, liability insurance, a building lease, property taxes, ... you get my picture. That has to be the number one concern for a business, other wise you can't even plan to be around to help these customers... which by the way make up every race.

Secondly. you are putting them in a very bad position... they are now responsible for your actions with these clients! Whether you are giving them instructions in the gym or not, it is definitely something that someone could choose to sue ... if they chose to! And even though, you are the one giving them instructions/ training tips... the gym can now be added to that as well. Did you also know that each and every member of your family could also be tagged into that same lawsuit? The employees and their families of the gym are also responsible in a lawsuit.While I may not have given you the suggestion that you want, it's simply NOT fair to put everyone at such a risk. While you were in the military doing this job, the US government(hence the tax payers) and the military are responsible for your and your comrades actions. It's a much larger situation, than most people are aware of. I'm not
mentioning this to you to be negative.. the bottom line is that it is reality in todays world!

I'm sure that you have heard of many of the cases that contractors have been involved with... some contractor will work without insurance and underbid other contractors, and while competition is a good thing, it's not when they are not insured and the homeowner is left with a problem that the contractor is ultimately responsible for. The bottom line is this: there are many good videos/books out there to help people get in better condition ONCE they have had a physical, why don't you recommend those and in the meantime take that internship? It sounds like you will be a great advocate for people and getting them in better condition, but you will be much more helpful with more training/certification under your belt.
