The heart and soul of Shogun Fitness is Shogun90. We took the best tools, training methods, and nutrition programming developed and discovered over a decade, and combined them all into a powerful 12-week program that will transform your body and change your life.

Traditional personal training struggles with the work and time required to make gradual lifestyle changes–and this makes the average fitness journey longer, harder, and less rewarding than it should be. 


At Shogun Fitness, we believe your body WANTS to be fit, strong, energetic, lean, and injury–resistant, and we believe that if we give your body the tools it needs in order to be this way, it can change quickly! Fast results are rewarding, exciting, and teach us more about how to build a sustainable lifestyle of fitness–that’s why we believe in our mission of getting you better results, faster, for less time and money. Shogun90 is an integrated program in which every element is designed to work with and complement the others, giving you the power to achieve extraordinary results that last.


Shogun90 is everything you need to transform your body in one complete, customized, 12–week program:

  1. A customized blend of one–on–one training sessions and dynamic Team–Training sessions using our revolutionary ShogunCore movement system–teaching you to activate over 650 muscles in your body to create incredible power, make you practically injury–proof, and burn more calories than any workout you have ever experienced.
  2. Personalized meal plan, meal building guide, and lean–eating recipe book packed with delicious meals
  3. Macronutrient analysis and food–logging training–we’ll get an x-ray view into how your body uses protein, carbohydrates, and fats, and teach your YOUR perfect numbers so you can look, feel, and perform your best with total peace of mind for the rest of your life
  4. Customized nutritional toolkit designed specifically for you in order to solve problems and fill in gaps in your meal plan, eating and training schedule, recovery process, and food likes/dislikes
  5. Online workout video series to keep you on track with the program in between your workouts with us
  6. Total coaching and support throughout–this program is super powerful, and your results are our highest priority. We’ll do everything possible to ensure you have an amazing experience and get the transformation you earn.

If you're looking for the best personal trainer in Seattle, look no further! I went on Yelp looking for a trainer to help pull me out of my rut. I was fairly healthy to begin with but was bored with my normal routine and not getting the results I wanted on my own. I decided to give Jef a try because he had the top ratings on Yelp, and now I know why he does!

Was looking for a kick start to get back to my old self. Jef created a great workout and nutrition plan for me to follow for 12 weeks. Following the program and having Jef keep me accountable and motivated was just what I was looking for. The first week alone I dropped 7lbs of fat and noticed an increase in strength. If you are looking for someone that can help you achieve maximum results and keep pushing you to your goals, there is no one better than Jef and the staff at Shogun Fitness!

Incredible! Jef truly is a master trainer! Not only are his workouts effective and exciting, he also takes time to coach on nutrition. He's always on time, always excited to train and always has new exercises to keep it interesting!
