Hi Shannon. If you (or the person getting certified) has no hands-on gym training experience (training yourself and/or designing programs and training friends/family), then I would say ‘no.’ The one major missing piece with a strictly home study certification is the hands-on, in-the-gym experience.
Yes, there are other options for getting certified. Many certifying organizations hole certification ‘events’ where you go to a site for a learning and certification experience with a live instructor. Others offer a combination of both online and in-person. And yet others will allow for home-study for the written testing portion, and may require a ‘practical,’ in-person training testing.
As you can see, there are several options. Good luck!
