Absolutely! We do offer military and first-repsonder discounts on all of our services at Hot Ground Gym®.

Are your adult obstacle courses the same as Ninja classes for adults?
Not really, our indoor obstacle courses and fitness sessions are a wonderful experience to behold, but we would not call them a “Ninja Class”, we call them “Military-Style Fitness Classes” or “PT sessions”.
