Iron Lion Gym

I’m a professional personal trainer who has a personal trainer.
When someone learns that about me they’re usually surprised and extremely interested in who I would choose to train with… 3 times a week… For years and years… And why.
Erick Northroup is the best personal trainer and coach in the industry.
We actually started 7 years ago by «fixing me.» We got dysfunctional joints moving the right way and and alleviated knee pain I had been told was hereditary and would only get better with surgery.
After that Erick made me an athlete.
I learned how to foam roll, stretch, warm up, eat, manage my workouts, and train for events.
6 years later I feel better than I knew I could, I’m stronger than I thought possible, and I’m the best version of myself at work and play because I train with Erick.
And Erick trains at Iron Lion.
With Leo.
Who is also cool.

Leo rocks. Natashka was wantingk to get in tip top shape in order to wear new Versace bikini for beach vacation in Ibiza. Plus, usual diet of champagne and foie gras makes personal trainer very important necessity! Trainer Leo is like best secret weapon ever. Natashka feels and looks svelte, powerful, and highly energeticized. Big Thank You from my abs and glutes, and from Italian bikini!

Leo is a terrific trainer, the best I’ve ever had. I came to him with the goals of improving overall core strength, muscle tone, body alignment, and posture. I had also had a minor shoulder injury a while back, and wanted to regain strength and mobility. He has helped me on every point, exceeding expectations. He has a great «go for it» spirit, and his professionalism, expert knowledge of muscle anatomy and alignment of the spine, but above all his energy enlivens every session. I am feeling great about my body, and energized far beyond the gym.

Leo is the MAN! He has taken this 47 year old, injured, dilapidated and broken down body… and made me HARD (Not that way, you pervs!)!
I came to Leo after about 4 years of successive injuries and surgeries after years of being a dedicated runner and «crunches» guy. I had lost most of my motivation, was becoming late «middle age» flabby and pretty much felt terrible about my physical well-​being.
At first, to be honest I didn’t «get it.» Why wasn’t I doing sit ups? Why weren’t we pumping iron!!! Why was I do so many squats and dead lifts…
The core! Because of the core. I have not done a single «crunch» or «sit-​up» and my abs have never been so firm (wanted to say hard again, but too many pervs, also, ladies, I’m happily married — as they say a hard body is good to find).
Leo has patiently pushed me, trained me and guided me to a physical state that I would have envied in my 20’s. I can dead lift 205 lbs, and I weigh 170!!! And I don’t look like a bulky gym gorilla!
Leo loves what he does, does it like a pro, and knows how to bring it to you!
People always say they wish they could give zero stars or something and half stars… I wish I could give 6, heck 10!
Thanks Leo!

Finally, a trainer who knows anatomy and alignment from the inside out. Quick comments he makes have been life-​changing for my body. I have taken many kinds of classes and worked with trainers. Leo is the best by far. Instead of tailoring the workout to my injuries, he fixes them through stretching, manipulation, and «bungi-​flossing». I feel totally seen. And my wife loves the results!
At first I worried that his gym is small. Then I discovered I often have it totally to myself.

I have always stayed in good shape and have done a variety of things over the years including skiing, biking, running and triathlons. I used to go to the gym intermittently, however, after I got into yoga the gym visits stopped completely.
Unfortunately I then had to stop yoga because of an injury and was trying to figure out what to do to get muscle tone back without making the injury worse. Fortunately I found out about Leo and started working with him several months back. I have listened to a lot of trainers in gyms, although not trained with too many, and I can safely say that Leo talks more sense than any trainer I have ever heard.
He is passionate about his subject and that, combined with his great knowledge, really rubs off on his clients. Everyone one I see leaving his gym has a good word to say about him — even if they often look rather tired!
I have no hesitation in giving Leo five stars. He caters workouts to suit you as an individual and does not stick to one style dogmatically. In addition to that, he has a great sense of humor and is ready with a string of anecdotes and stories to help you get through the sessions. Check him out!

It’s hard to imagine Leo at Mill Valley Personal Fitness getting anything other than 5 star reviews.
When you are with him, 100% of his focus and considerable intellect is on you. He showed me early on that he was as committed to my well being as I was. One of his clear strengths is in customizing unique and thoughtful workouts that are individualized for your specific needs or limitations. I have met a handful of Leo’s other clients, and I am amazed by the variety of his clientele: I have seen middle aged ladies, getting fit later in life. Folks with injuries that limit their range of motion and need creative restorative workouts. Athletic paragons who are looking for a real challenge, as well as people like me who are looking to lose some weight and get fit.
I went in initially to have Leo help me with a chronic shoulder injury, an AC impingement, and I stayed because I was inspired, for the first time in my life, to be fit. Leo made me feel like I could make real changes to my life. I have always hated exercise and was expecting the same colorless advice that I have received from countless medical professionals and amateur athletes. Leo has an incredible understanding of body mechanics and human anatomy that you simply do not see in gyms. He ran me through some range of motion diagnostics, and by the end of my first session I could put my arm behind my back, which was a huge improvement!
6 months in, I am athletic in a way that I never would have imagined. I have lost 30 pounds, and my general fitness continues to increase. I have more hard work to do to get myself to a place that I will be both happy and healthy, but Leo has helped me to embrace the journey. We do lift weights, yes, but Leo will make sure that you understand proper form before he throws you into anything at all. We do yoga and he even has me doing very careful minimalist running. In addition to Leo’s expertise, he has a delicious sense of humor that makes a hard workout fly by.
Like everything else in life, you get out of this what you put into it, so when you are ready for a challenge or to change your life, give Leo a call.

For years I have been working on an old shoulder injury that all started while I was a baseball player (pitcher and catcher). I was no longer able to throw a baseball without tons of pain and nausea. Now, as a Chiropractor, I make hundreds of adjustments a week while having to use torque with my shoulders. This causes a lot of pain at the end of every day. I have tried many modalities to help this situation.
Then I met Leo. He examined my biomechanics and realized that certain muscles have been over compensating for years that need to chill out while other needs to start firing and getting strong once again. In the middle of my first session I was practically pain free and feeling like a new person.
I HIGHLY recommend Leo. He is not only an amazing trainer, but he has a super chill legit gym that anyone will feel welcome in. His knowledge of the body is very refreshing.
Thanks Leo!
