Our Team
Josh Kosier
Owner
Josh has had a dumbbell in his hand since he was 12. He’s trained in more gyms than he can count—big ones, shiny ones, serious ones—and through it all, he’s learned one truth: great equipment doesn’t matter if the energy is off.
What makes a gym great is the community inside it. That’s what drives him every day. Whether it’s him, one of the HQ's trainers, or an OG member, someone is always here to welcome you in with a good attitude and a solid spot.
Jenn Kosier
Owner
Jenn is a trainer who believes fitness is about more than aesthetics — it’s a pathway to confidence, connection, and personal growth. Specializing in pre- and postpartum training, bringing empathy and lived experience to help her clients reclaim strength and self-trust.
Jenn's approach blends progressive overload with realistic goal-setting and a supportive, judgment-free space. Whether you're just starting out or rebuilding after big life changes, Jenn is here to help you move forward — with purpose, joy, and resilience.

He’s passionate about simplifying fitness and helping clients become the strongest versions of themselves — physically and mentally.

Mandi’s goal is to help women reconnect with movement, feel at home in their bodies, and stay strong for the lives they want to live — now and in the years to come.
Alex Windhaeuser
Alex began his fitness journey as a teenager drawn to the structure of bodybuilding, which brought focus to an otherwise chaotic young adulthood. That discipline carried him through years in restaurant management and international travel before settling down with his wife and their three dogs (two Blue Heelers and a German Shepherd).
He discovered a passion for coaching in his early 20s while training his younger brothers, who went on to compete in college sports and high school athletics. Now with over a year at HQ, Alex is committed to helping clients build sustainable habits across sleep, nutrition, supplementation, and training — creating a more balanced, healthy lifestyle that supports both body and mind.
