Good answers so far. I especially like Eric’s suggestion of doing an initial consultation at the client’s facility.
And then, depending on the quality and variety of equipment, be open to other areas around the client’s apartment complex. Do they have a pool? Is the weather favorable for training outdoors?
Does the client want you to teach them merely how to use the equipment they have access to? Or are they open to using you to teach them that, THEN provide unique training experiences each session with specialty equipment, then have them do “homework” with the equipment they have access to? You will have your client a lot longer if you can show that you’re adding value over and above teaching them how to use the machines. What I like to do is have a mix of home-based exercises and exercises that the individual can only get from me so that *I* am adding value. For example, I bring bender Balls, gliding discs, and a few other lightweight tools to in-home and apartment-based sessions. That way, they’re getting variety in their movement and can do “homework” with the equipment they have available.
