I would like to go I want to lose some weight the only problem is that I don't know if there are coaches who speak Spanish

You would have to go in or even call and ask if their is

Myself, I will say it's a good place. Nice greeting, I'm wheelchair bound, and I get great suggestions and demonstrations of machines in helping me to achieve my goals.

That is something you would need to go in and ask at the front desk. There is likely at least one Spanish speaking trainer, I'm sure.
