  • What We Offer

    We offer a wide variety of classes and programs intended to promote physical activity and self confidence in children ages 6 months to 8 years.

    For children 3 and under we offer loosely structured 45 minute long parent/child classes. We offer recreational gymnastics for children ages 3 to 8. These hour long classes are structured with age appropriate and creative lesson plans. We also offer other programs like Sports Skills and Ballet, all taught in the Junior Gym style. As a perk for our members; we host open gym which is a drop in hour of free play twice a day Monday through Friday, and once a day on weekends.

  • Our Facilities

    We are proud to be a family operated small business – we are not a chain! Our friendly staff has created a great reputation for being patient, caring and creating an exciting and safe class environment. Ask around. We know you will hear great things about Junior Gym!

    NEW LOCATION!! Our newly renovated spacious facility provides a safe and challenging setting for all of our classes. Our large variety of equipment is moved each week to ensure a stimulating environment.

  • Beyond Classes

    In addition to our classes; we offer birthday parties and seasonal camps.

    Our camps provide fun weekly themes, and a combination of organized games in the gym with art projects, story time, healthy snack and more. We'll keep your kids active and having fun.

    Birthday parties are 2 action packed hours of music, games, cake and fun! Kick back and enjoy the party while our staff takes care of everything. Make your child's birthday one to remember with a private party at Junior Gym.
