Testimonials

What do my clients have to say?

Krista Morrison

I love working with Blake! As someone who doesn't particularly love working out, I find that I need direction and encouragement from someone who knows how to push me to be the best version of myself. Blake has been just the person I need as I press forward in my fitness journey.

Ken Pecus

It is my absolute pleasure to provide my strongest recommendation for Blake. As a former owner of two nationally branded health clubs, I have a clear understanding of what a health and fitness instructor should be providing. In addition to be an exceptional professional in his counseling, he himself looks and lives the part of a quality healthy individual. I look forward to achieving many more health milestones in the future with Blake's encouragement and counsel.

Drew W. - Life Sciences Executive

“I have worked with Blake for many years - both for strength training and rehab from injuries and surgeries. After I had rotator cuff surgery a few years ago, Blake designed a program to help me strengthen muscles around the injury, helping improve overall shoulder mobility and function. Blake knows his stuff. He reads constantly to stay on top of the science behind fitness and strength training. I highly recommend him.”

Del Phillips

Blake is an amazing personal trainer, and fitness expert. On top of being a knowledgeable personal trainer, and a compassionate person. Whenever I've worked with him he always makes me feel comfortable in my own skin. He empowers me to be the best self I can possibly be. Few trainers operate on such a level.

Holly M.

I highly recommend Blake to anyone wanting to elevate their fitness journey. His deep knowledge and years of experience make him an exceptional trainer. Not only is he well-educated, he's truly passionate about helping clients achieve their goals through tailored workouts that are both challenging and effective. I've seen incredible progress under his guidance. He's the best in the field!

Adam Kaoullas

Blake is a motivational fitness instructor with a passion and great knowledge for the physiology of the human body and getting tailored results fast. As a gym owner and debuting professional boxer, I can't recommend Blake Koehn high enough!

Jenna Rubin

Blake's educational background shows in his ability to create individualized programs for the long term. Blake taught me exercises that benefited my weaknesses specifically which no other trainer had ever addressed. I am now stronger than ever before and feel better doing my day to day activities. Blake's incredible background makes him the trainer to go to if your looking for an above and beyond fitness experience.

Lyrica M.

Blake is a positive, knowledgeable and amazing trainer to work with. Having a rare muscle disease and not knowing what’s best for my body was something that I struggled with. Blake took it upon himself to research the disease so that he could train me safely and with results I would be proud of. Despite my physical limitations, he always pushed me and believed in my abilities. I couldn’t be happier!

Wyatt Hinshaw

Blake and I have been working together for close to five years now, both in person and virtually. He's developed workouts to accommodate my ever changing needs - from a torn ACL to chronic neck / nerve issues. Blake's also helped me better understand and appreciate the connection between mind and body - opening my eye to a brand new way to approach my mental health.

Riley Larson

Blake is one of the best trainers I have worked with ever! As a college football player, his workout programs have allowed me to take my game to the whole new level. When I am done with my workouts I feel absolutely drained which is such a satisfying feeling. Blake's knowledge is unbelievable and always helps me with whatever I need, motivation, nutrition or just personal tips on how to nurse an injury.

The Oxygen Advantage

While it's clear that breathing is essential for life, far fewer understand how the way we breathe (our breathing mechanics) can significantly influence our overall quality of life. Beyond simply sustaining us, breathing patterns play a critical role in our physical health, mental well-being and both physical and cognitive performance. Controlled by the autonomic nervous system, breathing plays a fundamental role in energy production and is critical for generating adenosine triphosphate (ATP), the molecule that powers nearly every cellular function. From the nasal passages to the alveoli in the lungs, the respiratory system continuously adapts to meet the body’s shifting metabolic demands. In this article, I present a science based overview of oxygen’s role in human physiology, examine the systems responsible for its transport and utilization, and outline evidence based strategies to improve oxygen efficiency and effectiveness to support optimal health and performance.

Understanding Back Pain

A significant percentage of individuals will experience substantial back pain at some point in their lives. While not all acute episodes develop into chronic conditions, even short-term pain can meaningfully disrupt quality of life. In this article, I will provide a comprehensive overview of spinal anatomy, common movement patterns and behaviors that contribute to back pain, and evidence based strategies for prevention, management and relief. I will also explore key considerations for those aiming to avoid injury, recover from back related issues, manage intermittent or persistent pain, or navigate the complexities of pre- and post-operative care. The insights shared are informed by leading experts in pain science, clinicians and researchers who have dedicated their careers to both academic study and real world application.

The Physiological Menu

Thermal stress offers the unique ability to deliberately influence various physiological processes within the body. This intentional "reset" enables the development of personalized strategies to support individual health and wellness goals. The benefits are extensive and often occur simultaneously, whether the focus is on cognitive enhancement, injury recovery, glucose regulation, or hormonal support. In the following, I will provide a concise overview of the scientific principles, empowering you to make data-informed decisions when tailoring your wellness strategies.
