Bring your bouncy, active kiddo to Coach Nina and Coach Pencho and they will work miracles! . My daughter loves being here and working hard! TNT isn't easy, but the challenge drives her.

Clean, safe, friendly staff. Coaches are very helpful with their teaching. Definitely different from previous Gyms we have been to. Worth the wait to get in and worth every penny.

My daughter started at age 4. She has really enjoyed her experience so far. The gals have all been helpful at the counter when we have needed anything. Coaches have all been friendly. Some are more structured and helpful with technique than others. Facilities are clean and parents are offered a couple of viewing options.Areas of improvement: Coach turnover seems high. We've been attending for 6 months and we've had 4 different coaches during this time frame. Limited classes available for homeschool families with older children. I'd love to see a daytime class for my boys to attend during the week. Especially for children with sensory issues. Our class lately, has not started on time, therefore, the girls are missing out on 5+ min of time. Price is a little steep $95/month (4 classes, sometimes 5 if your day lands on an extra week)...seems to be the going price for anything here in San Antonio (we are a military family and have lived in larger cities where prices are not this expensive). No make ups are offered and no refunds, which, I believe encourages parents to send their sick children to the lesson so they don't lose out on the money. Parking is fine during the day hours but I have experienced the evening parking and they need a larger lot.There are definitely areas for improvement. I hope management will read and evaluate for the future.

It's Sunday evening and first time attending a Birthday Party 🎈🎉🎂 for my granddaughter at a gym. The party hosts were hospitable. Very nice and helpful. Reserved from 6 to 8 pm. About One hour and 15 minutes of gymnastics play. Parents can leave their child at the party or stay and observe from the balcony. Towards the end of the gym time, parents can come down to take pictures. Afterward, head to the room where its birthday party 🍕, 🍰, and presents time. The kids had a great time.
