TRUE STRENGTH
FITNESS
San Francisco based strength and conditioning coach and jiu jitsu black belt
"Nate is the man. I had lots of good boxing training coming up in the fight game, but there is not a lot of good Muay Thai out here so that was always a weaker point in my MMA game. After the first time I sparred with him at Valko's School I knew he was the real deal. He kicks so hard man! He helped me with all the technical aspects of Muay Thai and helped build a style for how I like to fight. Now I can get in there and confidently mix it up with dangerous thai boxers. I feel unstoppable! You might even see me walk off with a head-kick K.O. pretty soon!

"I have had the pleasure of working with Nate Sherk as both a martial arts training partner and a strength and conditioning coach for the last 3 years. What makes Nate so unique as a trainer is both his life as an athlete - both in all facets of the combat sports, as well as powerlifting and endurance training - and also over a decade in training clients, he really understands every facet of exercising for every approach. Not only can he help basic clients reach weight loss or basic strength goals, he can also help more advanced clients prepare for combat competition or for marathon or triathlon events. As an aside his detailed approach to being a well rounded athlete can help prevent or rehab various injuries which are often the result of a lifetime of incorrect training and the imbalances which this can causes. If you are looking for someone who really knows his "stuff" there is only one trainer for you - Nate Sherk!"

"I've been training with Nate on and off for about six years, and he knows his stuff. When we first got together, my goal was to have the explosive power needed to win cycling races. He put together a great routine for me while training in the off season to build some massive strength in my legs. Then a few years later, my goals have changed and jumped more into a mass building stage, since we've gotten together almost a year ago and he showed me another routine for upper body as well, i've put on a solid 25 pounds of mass.
Now, I'm sure not everyones goals are to get big, but it's nice to see a trainer who can get you where you want to go, and Nate is that guy. If you need to lose weight, he can help out there too. The dude knows his stuff."

"Working with Nate has been one of the most transformative experiences of my life. I've had other trainers before, but I felt like they were just going through the motions. From the first consultation Nate was different. He helped me set goals and really listened to me when I discussed my struggles with fitness and exercise. While he always pushed me and challenged me he was also very supportive and encouraging. I really started feeling like my workouts were about me and my well-being. For the first time in my life I started believing in my own ability! Now, just over one year later, I'm over 50 pounds lighter, went from a size 14 to a size 4, and I feel better and more confident than I ever have before."

"My six-plus years working with Nate have been the most productive and inspiring in the 20 years that I've been actively engaged in fitness and wellness. During our sessions together, we've:
- Added three inches to my biceps
- Added more than three inches to my chest
- Removed over 15 inches from my waist
- Increased my max weights on every station in my workout
-Decreased my body-fat% from 32% to 14.5%
Not as tangible but just as importantly, Nate taught me:
-How to lift smart AND heavy
-To vary my workouts from session to session
-To push myself much harder than I ever thought I could
Now, I'm fairly strong ... and marginally hot. Supersets, death pauses, stupid-heavy sessions, and shirts that used to be loose. I can't think of a better trainer to help you reach your own goals."

"Crossfit, kettlebells, plyometrics, power-lifting. You name it. I've done it all. Nate is hands-down the best person I've worked with in the Fitness industry. His program-design is well thought-out and tailored to my goals. He always challenges me and he never slacks. Since beginning with him I've increased every single athletic metric: Speed, explosiveness, endurance, strength, coordination and balance. I've never felt as dialed-in as I do now and it shows in my performance. I took home the gold in my very first Jiu-Jitsu competition recently and I know that the level of athletic conditioning I achieved working with Nate was a huge part of that success."

"I began training with Nathan Sherk in December 2011. From the very beginning, Nathan demonstrated that he is a knowledgeable and supportive personal trainer. He knows what it takes to lose weight with respect to proper eating and makes sure that his clients have realistic expectations based upon their personal commitment and abilities. Nathan understands the physical and psychological challenges that people face when trying to lose weight and get in shape. When I started working with him, I was also going through intensive physical therapy for my arthritic knees. Nathan customized workouts in an effort to not make my knee pain worse. My knee pain is much better, but he is still aware of how my knees impact what types of exercises I can perform. During the time that I have been training with him, I have lost 33% of my body fat and increased my level of endurance, balance and strength. I highly recommend Nathan Sherk to anyone who appreciates a knowledgeable and supportive trainer."

"Nate is a great trainer and a great coach. Some trainers go through the motions and put you through the "routine" but Nate will find your limits and then gradually push you beyond, so that you see improvement, all the time staying upbeat and positive. Nate is highly recommended as a trainer."
