The trainers and the company are both cheerful and flexible.
The trainers know what they're doing, and they readily adjust the workout plan to accommodate my body issue(s) du jour, whether it's a painful joint or just some overall weakness due to missed sessions. They are only and always encouraging (and never, ever shaming).
I also appreciate that I can cancel workout sessions (with 24-hour notice) to accommodate changes in my schedule without being charged a fee. Life happens, and Fitness Together makes room for that!
