Soon you'll be buying backpacks and sending your child off to school, maybe for their first year of Kindergarten, and there's one school ready skill that often gets overlooked: focus.
Our Preschool Gymnastics program helps little ones practice listening, following directions, taking turns and staying engaged, all through movement and play. Every obstacle, balance beam, and new skill encourages children to concentrate, problem-solve, and build confidence in a fun environment.
This school year, give your preschooler a head start by signing them up for our 12 week Flip-N-Grow Preschool Pass. Register them today with only one payment required at hinrggymnastix.com/preschool-pass.

Gymnastics gives boys so much more than flips and handstands, it builds the foundation for success in almost every sport they'll play. From football and baseball to wrestling, soccer, basketball and beyond, the strength, balance, coordination, flexibility and body awareness they develop in our classes with go with them for years to come.
Whether your child dreams of competing, wants to improve in another sport, or simply needs a fun way to stay active, boys gymnastics is one of the best investments you can make in his future. Learn more at hinrggymnastix.com/boys-gymnastics.

Meet Coach Alaa, who operates by a "believe you can and you're already halfway there" attitude, which shows in the way he coaches. Coach Alaa has been with the Hi-NRG family since fall of 2024 and you'll see him in the gym coaching tumbling and gymnastics classes. In his free time he participates in martial arts tricking, which he's been doing for 12 years and involves a lot of the tumbling skills he's teaching athletes. Coach Alaa really loves seeing when his athletes stick that skill they've been working so hard to land. He says you can see the confidence in their eyes and there's nothing more rewarding than being a part of that.
It’s always exciting for us to get to share snippets of what happens during class at Hi-NRG and this Confidence Clip from our Tumbling Program really shows just how explosive and powerful our athletes are!
