They changed my life.

I was diagnosed with severe rheumatoid arthritis ten years ago and my life was permanently altered. Instead of golf and running, I spent my time at hospitals and doctors’ offices trying to find the right medications for my condition. There is no cure for RA and it is a cruel, debilitating disease. I went thru numerous combinations of medications until the doctors found the right one. I practice yoga and stick to a non-inflammatory diet but still was in constant pain.

My client told me about S10 Fitness when he heard my doctor had advised me to have rotator cuff surgery. I began PT and training with Dave and Chris and it has changed my life. I have achieved almost a full range of motion in my shoulders as well as strengthening my entire body to better combat my disease. I am now playing golf again with my son, riding bikes and walking my 2 Alaskan Malamutes.

S10 fitness has not only helped me physically through rehab and training, they have helped me mentally by changing my daily outlook on life.

I am a positive individual but pain has a way of eroding your goodwill. Now I know I have the answer and I cannot thank Dave, Chris and Kaitlin enough.




I suffer from Sjogren’s Syndrome, an incurable disease which is the evil sister of Lupus and Rheumatoid Arthritis.  After years of hospital visits, ambulance rides, days of living on the floor, epidurals, injections, physical therapy, medications, and anything recommended by my doctors, I had resigned to giving up.   My partner recommended S10 fitness, saying they “fixed” his back.  I was skeptical, overweight and desperate, but willing to try one more thing. 

I dusted myself off, fresh out of a walker, hobbling with a cane, and headed into S10 in August 2012.  The first few months were full of feeble movements.  Those movements alone were discouraging, but Dave and Chris were beyond encouraging.  They stared me in the eyes promised me that I WOULD progress.  What an understatement!  Okay, the tears are flowing now…

I feel I owe my life (from 2012 on) to S10 Fitness.

If someone told me two years ago, that I would be standing on top of a Swiss ball, or doing 360’s on and Indo board, I would have laughed.  Instead, I now laugh at Chris’ crude jokes while balancing like a boss!  I love this place and couldn’t recommend it enough, as a first or last resort!

P.S.  They deserve extra credit for suffering through and allowing me to listen to Misfits Radio on Sirius.




In December 2012 I had back surgery for a herniated disc. Six months later I was still living in pain and couldn’t find a doctor to help me. My husband found an article about a power lifter, who had a similar injury to mine, that was “fixed” by Dave and Chris. I had to see if they could help me too.

The only problem was I live in Houston, TX. I called and without hesitation they took on the challenge. We started working over the phone with simple exercises and constant updates.

They learned I was very impatient and I learned they were always right. In September 2013 I flew to San Diego for a weekend of torture training. I walked into S10 Fitness at a 9 out of 10 on the pain scale and flew home at a 3. I left with homework and a promise to return next month. We kept in touch almost daily with progress reports, but mostly I was asking if I could do more or go faster and Dave and Chris always saying no. I flew out once a month so Dave and Chris could work their magic on me, and by January they had me pain-free. It has been a year since we started our long distance training relationship and I am back to lifting, hitting new PR’s and training for a half marathon I never thought I would be able to run. Dave and Chris have a gift. They gave me back my life, pain-free, and I am forever grateful.




When I first ever was introduced to Chris and Dave I was 262 lbs of overweight and out of shape blob roaming the streets like a sad fast-food scavenger.

I told them my goals and visions and was met with the best intentions and constant motivation. Not one time was I doubted nor given any less attention than the next individual. Like the others I felt like I was put in front of there own life to help reach my goals.

Through hard work, dedication, killer diet plan, and constant push, I was flabbergasted at the results.

Not a day went by I didn't see a pound or more fall off!

After 9 months I signed up for a Jiu Jitsu tournament, the weight I was destined for was 155lbs. Chris not only helped me reach that weight but stay in the best shape ever and helped me win GOLD!!!!

Now fast forward a few years I've been able to hold the weight off. I now no longer fear the gym - I live for the gym. To this day there is an open connection between Chris, Dave, and I for any health questions! I would recommend S10 Fitness to anybody from the average person, people that are rehabilitating, and too athletes. The knowledge of weights, stretching, rehabilitation, weight management,  and most importantly the human body is bar none.





I crawled into S10 when I hurt my back deadlifting. Chris and Dave took such excellent care of me. I herniated two discs, and they knew how to bring me back to walking again.

Their patience and upbeat attitudes have me hope.

They had me up and walking and back to lifting in no time. It was a battle. You two will never know how much I appreciate you! You have such caring hearts, and am forever grateful. Right now I'm training for State Champs then State Games in Olympic Lifting. I feel Strong. I owe it all to you guys. Much Love.




I love working with this team. They keep my workouts interesting and really target my specific needs. Especially as a dancer I need a very tailored regimen. Thanks guys! You've kept me healthy to keep following what I love doing!




After just a few short hours with the guys at S10 I've been able to pin point problems and find easy to implement solutions that will help me for life! So glad I stopped in and if you wanna do away with pain or use your body's full potential, you should stop in too!





Hands down the best place I have been to for rehab, maintenance and prevention of future injuries.

As a professional MMA fighter, I am always hurt and S10 always finds the issue and helps me in correcting it. I would not have been able to fight on two occasions of they didn't help my the knee pain I was having.

Aside from getting me through my injuries with their protocols, they also take it one step further and actually explain why they are doing what they are doing so you are being educated; which will help aid in prevention of future injury. I highly Recommend these guys for rehab and strength/conditioning.




This place is one of a kind, first rate! If everyone cared half as much as these guys about helping people feel better thus able to live better...the world as we know it would be exponentially better. S10fitness=priceless. Carry on.




Legit facility with legit trainers! I highly recommend this place!



S-10 Fitness is AB-SOLUTELY amazing.

The trainers here are super knowledgeable and have their A-game on at all times! They know the science of fitness and tailor workouts for the specific needs of their clients.. it rocks :) :) This isn't some corporate warehouse gym where they just want your cash and don't care about what happens after that. They have truly amazing personal touch and compassion for all the needs and obstacles that their clients are trying to overcome. 

The atmosphere here incredibly positive, encouraging, and they really have a knack for getting you to push your own limits, which is amazing for someone like me (a fitness novice) who was never naturally athletic and fairly overwhelmed by this whole process. 

The trainers here will take you step by step and break everything down for you, and get you really excited about fitness in general!! 

They also have a nutritionist on staff that will take the mystery out of healthy eating. 
S-10 designed me a custom food plan and more importantly took the time out of their schedule to teach me the science of eating right which is just as important as the fitness itself...

This place is truly something special, I would tell those people who want to start on their fitness journey but are intimidated by the whole gym thing to give S-10 a shot, you'll be amazed at what you are truly capable of!




I asked my friend Rob to give me a few pointers for leg work. He invited me to open gym at S10 Fitness (Saturdays). They not only blew my legs out (in a good way) but they also taught me how to roll out, stretch and blast my entire lower body. If you are serious about any goals be it strength, size or general know how you will find it at S10. Thanks guys.





I have been training with Dave for years. I ran my first half marathon a few years ago and it was awesome! I never thought that would be something that I would  or could do.

I discovered my passion for lifting and I am stronger than I have ever been.

I am able to squat 250lbs and I am almost at a 400lb yoke! I continue to be challenged and inspired to achieve more each and every session.

Dave is not only my personal trainer, he has become a fitness mentor and one of my best friends! Dave, Chris, and Kait have really set the the diamond standard for what a personal training facility should be! Thanks S10 for changing my life! Up next..... 500 lb tire flip!




My name is Bella Virgilio, otherwise known as Other Mom “OM” to Dave Sten and Chris Daly of S10 Fitness. I was introduced to Dave and Chris by my son, Jimmy, on Christmas Eve 2008. Dave was my son’s personal trainer and out of concern for me Jimmy hatched a plan for Dave to meet up and talk to me. What better time than an Italian family Christmas Eve full of food, drink and laughter.

At that time I was 3 years post-op for major abdominal surgery. I was feeling quite down and basically useless. Only allowed to lift no more than 15lbs and because of major scar tissue not able to sit or stand comfortably. I had 2 granddaughters that I wanted to be able to keep up with and just couldn’t do it.

After talking to Dave and hearing that Jimmy was so concerned for my well-being I told Dave I would make an appointment to come and see him. Back then it took me awhile to get up the courage to make that appointment. You see, at the time I weighed 260lbs and was afraid to go to a gym where all the “fit people” worked out. Finally showed up at the gym 3 months later . Dave was tapping his watch and Jimmy was standing there laughing! Thus started my journey to a better self-image and better health. I followed Dave and Chris on their journey from the “big name gym”, to their garage gym and on to S10 Fitness. They are not only great trainers, but great friends and caring people. To make my “Other Family” complete was the addition of Dave’s beautiful wife Kaitlyn, who always greats me with a hug and a smile.  

If you want personal trainers who treat you like a person and not a number coming through the door give S10 Fitness a call. Be warned, they also both have a wicked sense of humor, so be ready to laugh while you work out!



Truly Life Changing!

I can honestly say that i don’t know where I would be without Dave Sten.  I am fortunate that he has been my trainer for many years.

Initially I trained with Dave to lose weight and gain muscle, which I did.  I really liked heavy lifting but I just can't do that anymore. 

It turns out that the Scoliosis I had as a teenager has developed into Spondylolisthesis and Arthritis as a middle aged adult.  Basically, my vertebrae are slipping out of alignment.  My back muscles overreact and become very stiff on the left side causing pain.   After my worsening back situation was diagnosed at UCSD I went for a course of Physical Therapy but didn’t feel improvement.  (It was a typical Back Pain Protocol, not individualized to my specific problems.)  I was lost, but THANKFULLY, Dave has been so helpful in working with me weekly to decrease my pain due to the chronic muscle spasms and maximize my quality of life.   Dave has an amazing understanding of all related muscle groups and why it’s important to not only break up the muscle tightness in the back but also work on various other trigger points and related areas to stretch as well.  Truly life changing!

All of this in a super positive environment!  The entertainment factor of the Dave and Chris combo makes for a fun gym environment.  They are good people!   Down to earth, real and will be your biggest fan and allay. 

Whether you are looking to improve your health, lose weight, gain muscle or aid in treatment of an injury or chronic muscular problem, I most sincerely and highly recommend David Sten at S10 Fitness! 




I have been working with Dave for over 6 years now, so I can say with absolute confidence that he is an amazing trainer.  I have asked Dave to train me for everything ranging from weight loss, to roller derby, to restraining wild animals, to lifting heavy objects, to helping me recover from a severe back injury.  Not once has he let me down. He has always been able to prepare me for whatever I have thrown at him.

Dave has helped me reach a potential that I never even knew I had.

Until I started working with him I had no idea how strong I was or what I was capable of physically.  He got me to the point of dead lifting 200 lbs which is a lot considering I only weigh 125 lbs. Now all I want to do is pick up heavy things and put them down!

No matter who you choose to work with at this gym, you will be happy that you went there!




I began training with Dave a couple of years ago, after throwing my back out several times, I decided it was time to get myself and my core in better shape.  So I walked in to 24 and was introduced to Dave.  My plan initially was to train a few months with Dave, get a routine down and strike out on my own.  I immediately felt a connection with Dave after our very first session.  He listened to my concerns and I could tell that he understood, better than I did, what I wanted and needed from the training sessions.

After a very short period of time I came to realize the benefit of having someone else, who knows what they are doing, to push and motivate you. So now, two years later,

I cannot imagine not having the sessions with Dave and I am in the best shape of my life.

Dave really understands how the body and muscles work, how far he can push you to get a great workout every session. Whenever there is a pain he explains exactly what the cause is and which muscles are involved.  Dave keeps things interesting by changing the routine, developing unique exercises, and adapting to the ability of his clients.  From one session to another, I often do not know what's in store for me...so I am always excited to get started.

The gym is great, very well equipped, but also very private.  The personal attention I receive is not only great for the body, but I always walk away feeling great both physically and mentally...I call the sessions my weekly therapy.




I met Dave in 2005 or 2006 (about 6 years ago) and started training. When we first met, I was definitely out of shape and soft around the edges, unhappy with life in general, and had a relationship with food that bordered on psychotic. Something just clicked during the first sessions.

I began to feel strong, in control, and confident. Those feelings only grew from there. Fast forward to now; I am a record holding and nationally ranked female powerlifter, I have a body I love, a relationship with food that some might consider scandalous, and a firm grasp (very firm thanks to powerlifting) on my life. Together, Dave and I have gone from deadlifting 150lbs to 350lbs, bench pressing just the bar to being able to push 185 off my chest. I can honestly say that things would look very different had it not been for that fateful day I walked into 24 hour and met Dave Sten.

Dave has a way of making you feel that you are his one and only client (though i know that is far from true).

He encourages me, pushes me, and refuses to see me quit. Sometimes I feel that he knows me better then I know myself. He knows what weights I can lift before I do, when I should back off and when I should push it, and what I am truly capable off. He is someone you want in your corner regardless of your goals.

On a side note -- He probably has more types of bars than you thought existed and the best Glute/Ham Raise machine in San Diego.
