Is it unprofessional to wear shorts to a personal training session?

Hello Chris Williams,
I believe long pants are more professional; but, of course, dress for the conditions in an appropriate manner like mentioned by Karin. Nowadays, there are plenty of comfortable clothing options for heat to wear long pants at all times. Just put yourself in client shoes and check the mirror during a practice session in private if there are any concerns. Close fitting clothing makes following a trainer’s form easier and covers up well.
Take care,
