The Slate Approach

Slate is not just a place to get a good workout -it’s an uplifting and diverse community. The backbone of Slate is made up of all the people who come through its doors everyday. Slate is filled with people from all backgrounds and professions and we welcome you to bring your experiences and passions when you join!

what we do here

At the heart of our program is functional fitness—training that prepares your body for everyday tasks and activities by utilizing natural movements like squatting, pulling, pushing, lifting, and jumping. These movements are essential for daily life, whether you’re carrying groceries, gardening, or playing with your kids. By improving functional fitness, we help everyone—from athletes to grandparents—move better, feel stronger, and stay active for life.

Strength Training is a key pillar of our program, building the foundation for lifelong health and independence. Our approach emphasizes practical benefits—like core stability and joint health—over simply increasing muscle size.

Metabolic Conditioning further enhances your energy systems, improving your ability to lift heavier, sprint faster, and perform better in both workouts and daily activities. These workouts are tailored to all levels, designed to optimize metabolism, burn fat, and support overall fitness goals.

Our program incorporates a variety of movements to build well-rounded fitness efficiently. You’ll train with bodyweight exercises like squats and push-ups, gymnastic skills such as pull-ups and handstands, Olympic weightlifting techniques, and cardio staples like running, rowing, and biking. This diverse approach not only keeps training engaging but also ensures balanced development while reducing the risk of overuse injuries.

Another cornerstone of our programming is HIIT (High-Intensity Interval Training). HIIT involves short bursts of intense effort followed by rest, offering a highly effective and time-efficient way to improve fitness. The benefits included burning more calories in less time, boosting metabolism for hours after the workout, and enhancing fat loss and muscle gain.

We believe fitness is for everyone, and our programming reflects this commitment. Whether you’re an athlete, a busy parent, or just starting out, we’re here to support your journey.

Our Functional Strength program focuses on quality movement to develop motor control, strength, and hypertrophy. While rooted in traditional strength principles, these sessions incorporate controlled pacing to promote intentionality and precision in every movement. The slower pace and deliberate exercises are designed to enhance everyday functionality and overall strength.

Our coaches will guide you through each part of the class—from warm-up to strength and conditioning—ensuring that the programming is structured, accessible, and adaptable for all fitness levels.

If you haven’t tried a Functional Strength class yet, now’s the time! It offers a refreshing change of pace from our usual Strength & Conditioning classes, giving your body the chance to focus on control and quality.

Class Times

  • Tuesdays & Thursdays at 5:30pm
  • Saturdays at 10:00am

As a USA Weightlifting (USAW) affiliated gym, we are committed to providing expert coaching and a supportive environment for lifters of all levels. Our Olympic Weightlifting class focuses on refining and improving technique in the Clean and Jerk and Snatch.

In addition to primary lifts, the class incorporates specific accessory work to address muscle imbalances, strengthen weaker areas, and support joint stability. This helps improve technique, overcome training plateaus, and reduce the risk of injury while building strength for heavier lifts.

Whether you’re new to weightlifting or have years of experience, this class is designed to help you elevate your performance and achieve your lifting goals.

Class Times

  • Tuesdays from 10:30am to 12:00pm
  • Wednesdays from 6:30pm to 7:30pm
  • Thursdays from 5:00am to 6:30am

Blending the power of breath with dynamic movement, our yoga class is designed specifically for lifters looking to enhance their strength training with improved mobility, balance, and body awareness. Each session guides you through a vinyasa-style flow that complements your lifting routine while promoting flexibility, injury prevention, and effective recovery.

Our unique sequences are crafted to engage both the mind and body, offering opportunities to refine technique, deepen practice, and achieve new fitness goals. The advanced variations of poses challenge your strength, but we also provide modifications and scaling options, so every participant—regardless of experience—can benefit and grow.

Class Times

  • Thursdays at 6:30pm

Kettlebells are uniquely designed for ballistic and unilateral movements, making them a great tool for developing athleticism, explosive power, and endurance. Including kettlebells in a training regimen with other forms of weight lifting (e.g., barbell or dumbbell exercises) creates a more well-rounded program that maximizes strength gains and increases overall performance. They are a versatile piece of equipment that can be used for basic strength training, balance and coordination, and metabolic conditioning. Most kettlebell movements require more time-under-tension and core stabilization, making them an incredibly efficient tool while minimizing the amount of equipment required.

Our Kettlebell Training program will include a mix of it all – honing skills and technique to challenge your joints and muscle groups in new movement patterns, building strength and identifying imbalances through unilateral movements, and increasing cardiovascular capacity with longer endurance workouts. We will focus on one skill at a time on a 4-week cycle during Thursday classes, and include a longer workout on Sundays.

Class Times

  • Thursdays at 11:00am
  • Sundays at 10:00am

Take a step beyond group classes to pursue your individual goals with a dedicated coach. Whether you are new to fitness or looking to progress your skills, personal training offers an opportunity to deep dive into your personal movement patterns and preferences around training. Please reach out if you are interested. Our coaches would love to work with you 1:1!
Some benefits of 1:1 training include:

  • Specific programming and personal instruction
  • Introduction to strength training and proper/safe form
  • Detailed breakdown of lifting movements
  • Varied styles of training
  • Facilitated recovery from injuries and injury prevention

About

I grew up on a small farm in Oklahoma and joined the military right after high school. I found CrossFit in 2008 while preparing to try out for the Navy wrestling team. I immediately fell in love with the training, the community, and the results.

After leaving the military in 2010 I got my Level 1 and began coaching under one of CrossFit Invictus’s original coaches. In 2012 I moved to Okinawa, Japan and coached at one of the most renowned gyms in the Asia region.

In 2016 I moved to Seattle where I became an owner and coach at Slate and eventually a Seattle Firefighter.

I have a wife and 5 kids so if I’m not at the gym I will likely be at one of the many kid activities or doing a cold plunge with my crew.

Why I coach:
I want to share the knowledge that I have gained having coached at other gyms with other amazing coaches. It brings me the most joy when the people in our community become healthier and fitter and knowing that I had a small part in that.

Fun fact:
When I started CrossFit I quickly fell in love with the sport. I qualified for regionals from 2012-2016. I have competed in the U.S., Okinawa, Hong Kong, Thailand, South Korea, and Australia.

About

I was born and raised in Seattle, WA and moved to the Bay Area where I played collegiate basketball at Sonoma State University. I spent several more years down there and had different opportunities to coach basketball at the college level, while also gaining experience working with at-risk youth and families through the foster care system. I have a huge passion for helping people build up their confidence and self-esteem, especially through physical activity and fitness.

I found Slate when I moved back to Seattle in the summer of 2020. I just started my Functional Fitness journey and found that Slate’s community oriented environment felt like a safe space to learn new athletic movements, ask questions, and build lasting relationships. I love functional fitness because it is inspiring to see what my body is capable of achieving!

Why I coach:
I coach because I love to build up others. Whether I am coaching youth basketball or adults at Slate, it is a privilege to be part of every athlete’s journey in reaching their goals. I take pride in being an educator and being a part of so many lives!

About

How did you find Slate or functional fitness and what do you love about it

I found functional fitness at a time in my life when I needed the competitive nature I thrived in during my years as a student athlete. I took that, plus my 10+ years as a coach of youth volleyball athletes, and blended it into a career of coaching adult strength and conditioning classes. After all, we are just big kids at heart! I have enjoyed sharing my passion of learning and teaching with those around me and couldn’t be more grateful to have found Slate Strength and Conditioning!

Where did you grow up and how did you end up in Seattle?

I grew up in the western suburbs of Chicago with my family of 9. I’m the oldest of 7 – I have 6 younger brothers! I had a burning desire to leave the Midwest and find somewhere new to call home. Packed everything I owned into a camper van, set my sights on Seattle and I never looked back. It continues to be the single greatest decision I’ve made in my life.

What do you do for leisure when not working out?

I read and play video games. I am a sucker for anything dystopian, zombies, or crime/horror. The more gore and guts, the better.

Why do you coach?

I love seeing people show up for themselves and watching them push past their boundaries. I also take great pride in getting to know you through the ‘Question of the Day’ part of class. Watch out – I may even get you to spill the answers to your password security questions at least once or twice.

Fun fact about yourself?

I’m also a welder! I went to school for 2 years and can weld in multiples processes, positions and mediums. I don’t do much of it in my current life, but I plan on owning a welder for weekend projects in the near future.

About

I’ve been a competitive athlete since I started swimming at age five back on the east coast. Since then, I’ve tried every sport you can think of (seriously, try me). After graduating college, I struggled to find an athletic outlet that held my interest. At first, I tried long-distance running (desperate times…) and started powerlifting with a personal trainer. A few years later, after moving to Seattle, I found rugby. It felt like the sport I was meant for, and I learned so much about myself, my body, and my capabilities. The community I built through the Mudhens has supported me through multiple serious injuries and ultimately, my retirement. Recuperating from these injuries led me to develop a more holistic training regimen that includes powerlifting, Olympic weightlifting, swimming (for my poor joints), yoga, and high-intensity metabolic conditioning. My focus moving away from competitive sports is to proactively protect my body against any ailments that age or life may throw my way. I am so grateful for everything I have learned on my journey, and for how flexible and diverse functional fitness training is for those of us who want to do it all!

Why I coach:
I believe that every person has an athlete within them that can be nurtured and developed to meet their specific goals, however broad or specific they may be. As a lifetime athlete, I’ve experienced a lot of different coaches, coaching styles, and team cultures. I am excited to take what I have learned about what works, what doesn’t, and everything in between to a new sport with a new team. Coaching is a continuously evolving discipline that requires a holistic understanding and balance of individual athletes (including myself!) and the larger community. I am so excited to continue my education on this path and to develop my inner coach with the help of my new team.

Fun fact:
I have a rescue greyhound named Superman (aka Manny, ManDog, Manfred, etc.)!

I will be seen smiling if/when:
There is an animal around that I can pet and/or stare at lovingly 🙂

About

I was born and raised in Seattle, and have been here my whole life. At home, I’m lucky to have a wonderful wife and two boys who keep life so full and exciting.

I started coaching in 2013, and it’s been a source of joy and growth ever since. I get so nervous before coaching every class, but that nervous energy drives me to give my absolute best to the athletes I work with.

Whether you’re stepping into the gym for the first time or chasing a personal record, I’m here to guide, support, and celebrate with you every step of the way.

Why I coach:
Nothing fulfills me more than knowing that I can play a part in someone’s fitness journey—helping them achieve goals they once thought were out of reach.

Fun fact:
I love to organize things. And I don’t know how to swim.

About

Although I wasn’t born in Seattle, moving to the PNW felt like coming home. I spent much of my childhood traveling between states and countries, developing a passion for culture and the environment. After trying multiple sports during my adolescence, I ultimately decided to pursue competitive soccer in college. My connection to the sport brought me overseas to train at academies in England and to work with a sport-for-development nonprofit in Malawi, Africa. I am deeply passionate about the power of sport to break cultural boundaries, build community, and foster personal growth.

I like to say that CrossFit helped save my life. After my first year of college, I developed an eating disorder and moved to Seattle to receive treatment. Although I first discovered CrossFit in high school during my college preparation training, it was during my recovery that I truly realized how functional fitness can change lives. In a world where weight, image, and “ideal bodies” dominate the fitness space, CrossFit’s emphasis on strength, empowerment, and community inspired me to develop a healthy relationship with food and my body. Having already worked as a personal trainer and soccer coach for years, I decided to transition into becoming a CrossFit trainer.

As a member of the queer community, inclusivity and acceptance are paramount to me. In my coaching, I aspire to provide a safe space for individuals of all backgrounds and identities to explore and enhance their relationships with their bodies. I am extremely open about my own journey and consider it a privilege to help others navigate theirs.
Fitness is as much mental as it is physical. Some of my proudest moments as a coach have been seeing my clients achieve what they once thought impossible and watching the ripple effect of that achievement reverberate through their lives. Fitness is for everyone and extends far beyond the confines of the gym.

I am grateful to be a part of the Slate community and excited to continue learning and growing as both a person and a coach alongside some incredible people!

WHY DO YOU COACH?
I believe movement can transform lives. I want to provide support, education, and empathy to help people explore their potential and establish a stronger relationship with themselves.

FUN FACT ABOUT YOURSELF:
I write poetry and am working on a book combining my writing with nature photography.

YOU WILL BE SEEN SMILING WHEN/IF:
