<p>Largely true, but though it varies by state, there are longevity parameters as well as age criteria. If it were two 40 year olds, and the trainer held a license for a number of years, it’s a non-issue.</p>
<p>In CT, I’m virtually positive that you must have held a license for three years AND be over 18 to train someone, even a sibling. I’d suggest the OP access her state mv laws through their website to verify what their parameters are.</p>
