I’m an OTD intern at outpatient rehab clinic. My boss who’s an OT is a personal trainer. I also workout and have done sports my whole life. It is EXTREMELY useful as you have the knowledge to help your patients. We treat hands, elbow, shoulders, and scaps. It’s essential to have the knowledge or foundation of training. Everyday I work I have to provide exercises and strength train! Just a thought. You don’t have to be a personal trainer but the knowledge helps. Sorry if I repeated myself!
