A gym near Apple Valley & Oak Hills

Close to Apple Valley, closer still to Oak Hills

ATG Fitness sits in Hesperia, between Oak Hills and Apple Valley. Coming from Apple Valley, plan on about 15 to 20 minutes behind the wheel. From Oak Hills it's shorter, roughly 10 minutes for most homes. We don't have a gym in either town; we have one room in Hesperia, and we'd love to see you in it.

Group classes with real coaching

Every class at ATG has a coach running it from the first warm-up to the final stretch. That matters if you're coming back after a long break, an injury or a few busy years. You'll get clear instructions, a version of each movement that suits you right now, and someone who notices when you're ready for more.

Pick from three formats. Strength & Conditioning group classes with Coach Alex build strength through structured blocks and conditioning. Mobility with Coach Russ focuses on back health and moving without pain, adding strength one step at a time. Zumba and POUND with Coach Michelle bring the music and the cardio, and first-timers fit right in.

For Apple Valley and Oak Hills families

Parents can train without booking a sitter, because a playroom with a TV sits next to the workout floor. Kids ages 6 to 12 can join the free Kids PE class, where an ATG coach runs games and movement skills. If you homeschool, our homeschool PE page explains how the class works for your family.

Your first week costs nothing

Start with a free week of unlimited group classes. The clock starts the day you first check in, not the day you sign up, so you can wait for a week that suits you. Try every coach, then pick the package that fits once the week is done.

We keep class times on the live schedule instead of on this page, because coaches update them often. Check it before you head over, book your spot, and come about 10 minutes early for a quick tour.

Know before you go

The gym gets warm since there's no air conditioning, so a water bottle and a towel are your best friends. Wear clothes you can move in. Your waiver is signed in the ATG app before your first class, which means you can walk in and start training.
