Alexa Mckenzie
My fitness journey started with a desire to feel stronger — inside and out. What began as a personal quest for confidence became a deep passion, leading me to become a certified fitness coach. Strength training didn't just change my body — it reshaped my mindset. I learned how to break free from unhealthy habits, tap into a strength I didn't know I had, and build confidence one rep at a time.
Now, I'm on a mission to help others do the same: move past obstacles, build discipline, and step into their power. I've had the privilege of working with a wide range of clients across every background and starting point — and I'm deeply invested in helping each one reach their goals and feel unstoppable.
My Experience
-
Strength & Conditioning
Built on intelligent programming — unconventional tools, heavy lifts, sweaty sessions and Conjugate Tactical training rooted in Westside Barbell methodology. Progressive, varied, and never random. You get stronger because the plan is built to make you stronger.
-
Group Fitness Coaching
Energy and expert coaching in the same room. I bring the structure and the push — you bring the effort. Every session is built to move you forward, not just tire you out.
-
HYROX Training Camps
Race-specific conditioning built around HYROX's actual demands — strength, engine, and the transitions in between. Train for the standard, not just a workout.
-
Nutrition Coaching
I've lived both sides of this — the quick fixes that don't hold and the shift that actually sticks. Precision Nutrition Level 1 certified, but my approach isn't built on restrictions or trends. It's built on what I've seen work, in my own life and in the women I coach: real food, real habits, and a plan you can actually sustain past week two.
-
Private 1:1 Training
A plan built around your goals, your pace, your standard. Clear instruction, real accountability, and the right amount of challenge to help you own your training instead of just showing up to it.
