Cardio boxing classes?

[Muncher]

I don't want to spend money joining a fancy gym as I won't be taking any other classes or training on the equipment. Where can I get cardio boxing classes in GTA (Markham or Scarborough) not contact boxing, and pay only for these classes?

Yeah, I got the Taebo series, but it's no fun doing it on my own; and the classes at community centres have non-professional instructors.
