PERSONAL TRAINING
HEAD COACH ASH
Ashley Stephen, M.S. Exercise Science
Ash owns Bucktown Assembly, though he'd rather you knew him for his coaching than his spreadsheets. A former collegiate basketball player and competitive HYROX athlete, he has little patience for training fads and even less for excuses — his approach is built on real-world experience and principles that actually hold up under scrutiny. With 10 years of coaching experience and a background teaching kinesiology at the University of Illinois at Chicago, he brings the kind of depth most gyms only pretend to have.
His style is direct, individualized, and refreshingly free of nonsense. He works with everyone from first-timers to clients navigating rehab to athletes chasing very specific performance goals, and he'll tell you exactly what you need to hear, not what you want to. The results, as it turns out, tend to speak for themselves.
COACH KB
Kim "KB" Bello, Strength & Conditioning Coach
Coach KB is a Strength & Conditioning Coach with 7 years of experience and a background in CrossFit and HYROX. She specializes in coaching athletes who are new to strength training, returning after time away, or preparing for HYROX and other strength-endurance events.
Her coaching combines strength training and purposeful conditioning to build real-world strength, endurance, and confidence, with hard work, a little humor, and a belief that strong women make each other stronger. She's especially passionate about helping women find their footing in the weight room, showing them just how capable they really are. Expect honest coaching, structured programming, and a clear focus on getting stronger and performing your best.
COACH ADAM
Adam Swantz, NSCA CPT
Coach Adam Swantz is an NSCA Certified Personal Trainer, International Kettlebell University Level 3 Trainer, CrossFit Level 1 Coach, and Hyrox competitor.
A former high school athlete and basketball coach, Adam is comfortable across a wide range of training styles, including strength, kettlebells, functional fitness, conditioning, and endurance, and he's the coach behind Kettlebell Club, built around the same movement quality he brings to every session. He works with clients to build results that last, one attentive rep at a time.
Outside the gym, Adam brings over 20 years of leadership experience with the U.S. Department of Veterans Affairs, where developing people and building genuine connections has always been central to his work, a commitment that carries directly into his coaching.
COACH KELLY
Kelly Jamieson, High Intensity Coach
Coach Kel is your resident high intensity coach. Kelly grew up competing as a track athlete and never really left the world of sport, and that same competitive drive now shows up on the other side of Assembly Track Club Bucktown, where she's currently programming for the Bucktown 5k.
She started coaching in 2020, and in 2022 ran her first HYROX race and fell in love with the format immediately. She's been competing ever since, bringing that same performance focused energy into every session she coaches.
Kelly believes knowledge builds confidence, and confidence changes your fitness journey. When someone walks in unsure of themselves and walks out knowing exactly what they're capable of, that's everything to her. Her goal is simple: give every person the tools to be confident inside the gym and out.
