Stronger Together.

Group fitness here doesn’t mean everyone does the identical workout. You can work toward your own goals, train around an injury, or scale a movement to where you are today — so what you get is a session tailored to you, in a group setting.

Every class is coached live — by Coach Sandy Martz or Katie McMorrow. Small groups mean your coach sees your form, adjusts your weight, and knows your name.

  • Coached, not just programmed — live cues and corrections every session
  • All fitness levels welcome, from first-timers to seasoned athletes
  • Structured weekly programming built around strength, conditioning & mobility
  • A steady group of regulars who show up for each other, not just the workout

Six Mornings a Week.

Three start times Monday through Friday, plus a Saturday morning class — six mornings a week. Choose the one that fits your week and let it become a habit.

Three Classes Daily

5AM • 6AM • 7AM
Monday through Friday
7:30AM Saturday

Small Groups

Small class sizes mean real coaching — technique refined in the moment, not just supervised.

Every Day Looks a Little Different.

Strength, HIIT, conditioning, mobility, core. The focus changes day to day; the coaching doesn’t. Every movement gets scaled to where you are, so the same class serves your first week and your five-hundredth.

You don’t need experience. You do need to show up ready to work — that part is on you.
