Customer Reviews

I cannot say enough about what the classes at HGG have done for my boy’s perseverance and patience and leadership qualities. And it’s a great workout too!

My daughter has been attending Hot Ground Gym since January and we couldn't be happier. We love the physical workout she receives, but the teamwork, motivation, and practical skills are outstanding​. I love watching her and the other children excel and smile when they complete something that may have seemed too difficult moments before. All the coaches are professional and great with the kids. In short, they are the best! Our entire family highly recommends Hot Ground Gym.

Cannot say enough good things about this place. The staff are friendly - if I'm sitting waiting the ones that are not with kids come over and introduce themselves. My son loves the classes, he is beginning to show belief in his abilities and more confidence. Your kids will have a ball. Give it a shot!

Both of my boys love "working out" here once or twice a week. The instructors are wonderful and the sessions are very reasonably priced. A hidden gem during the winter!

"I LOVE THIS PLACE!" These are the first words quoted words by my two sons who spent a day actively running, climbing, going through obstacle courses, and working as a team with a whole group of kids they have never met before. It can be challenging to find activities that are safe, engaging, and age appropriate for two very active boys during no school days and it's too cold outside to enjoy nature. Hot Ground Gym in Arlington Heights was recommended to us by a friend and her son. After one full day of high energy fun, my sons (ages 10 and 8) are already planning ahead for their next days off of school and asking to be signed up at HGG. They raved about Sam, the manager, and how he's knowledgeable sharing safety lessons and tips to the kids. Knowing Sam has a background in being a first responder and an Army Veteran, I feel very secure dropping off my sons knowing that activities are planned with safety in mind. From a parent stand point, this is the highest compliment to HGG! They are choosing to climb, run, lift, partner up with kids they don't know, and accept challenges to physical activities instead of begging to play video games, go to the movies, or watch tv! They will be repeat attendees for sure and I know I won't hear any, "I don't want to go... " whining from them!

It is amazing to see what Sam and his team do every day for the kids. Every week they have a different concept / theme. My daughters self confidence has improved a lot. I love the way Sam pays attention to every kid in the class and pushes them to overcome their obstacles both physically and mentally.

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”.
