Today we're talking to Jonathan Goodman, a trainer and author who founded the Personal Trainer Development Center (PTDC) in 2011. The goal of the site was to bring fitness professionals the information, support, and business guidance they needed but couldn’t find anywhere else. I’ve known Jonathan since right around that time, and he’s quietly — and sometimes not so quietly — built what I think is an immensely valuable resource for the fitness industry as a whole. We discuss the past, present, and future of personal training and where the industry will and won’t succeed in moving toward more remote and virtual training models.
