I agree with GD’s points, but I have to point out the opportunity cost for either choice so that you can make your own informed decision.
I coach at both Brand-X and Invictus and, like GD said, there are pros and cons for both. It depends on your demographic and how your classes are laid out. At Invictus, we have a large population of 20 to 30-somethings that have rather structured jobs and lifestyles—and are generally looking for a social aspect to their training experience on top of the actual exercise. To this, we found a class structure during early morning, lunch, and after-work hours to be great for these people. They meet like-minded individuals who are just getting started and can form a bond through the on-ramp curriculum. At one point, we did away with one-on-one on-ramp coaching since we were seeing so much success with the on-ramp classes.
We then started encountering several individuals who were not comfortable with any class structure at all until they felt comfortable, which usually meant after getting some idea of what they were getting into. This led us to re-introduce a first 5-esque option. Right now, we offer both on-ramps which are modeled after NorCal S&C but have been heavily tweaked for our needs, as well as one-on-one on-ramp personal coaching in response to what people were requesting.
In response to your original question, you have to consider the following. The on-ramp curriculum was obviously written with NorCal Equipment needs in mind. This means that if you do not have the same equipment inventory, you will have to tweak the framework to your own needs. Because of this, I propose the following:
Come up with what you think are good answers to every question you’ve asked here. We will chime in with possible alternatives or better alternatives depending on your line of thinking for a certain item. However, the critical thinking component of your coaching is very important if you plan to make this a serious job for yourself. We cannot provide all the answers for you off the cuff. Good luck.
