Body Matrix Personal Training

Due to health reasons, I had to take a break on work-​outs. Sergio has kept in touch and encouraged me to begin when I am able. Sergio cares about his clients and is an top example of a talented professional in the fitness business. Also, a strong member of the community, you can rely on his direction to get you where you’re going. Just show up… He’ll make you glad you did.

I reached out to Sergio last April to get in shape for my wedding in August. I went to a handful of trainers to try them out and see who I liked best. I have a lot of back problems, and I was immediately impressed with the way Sergio took note of this and really went out of his way to watch my back, movement, etc and protect it. But not only was he protecting it and deciding our work outs based on it, but he was also reading my body and looking into why certain things hurt it. A few months with him and my back was feeling stronger than ever. My dress was backless, so I really want to work on my arms & back so they would look great in the dress. On my wedding day, my photographer told me, «This may be a really weird thing to say, but you have a really sexy back and it looks great in all the photos.» VICTORY! I literally watched my body transform the last few months. Everybody asked me what I did to get in shape for my wedding, and yes, I did work out like crazy. But working out with Sergio CHANGED my body shape, not just making it smaller. It is hands down the best thing I have ever done for myself, and I truly believe that getting a trainer is the best investment one can do for him or herself. I told Sergio what I wanted, and he made it happen. We would constantly check in and reevaluate and see if my goals were changing. He also takes measurements so you can have even more proof how much your body is changing. My husband is still amazed at how different my body shape is… he is super impressed! My sessions with Sergio are dwindling, and I am not sure what to do with myself! Do yourself a favor and get in the best shape of your life with Sergio.

I started training with Sergio a short while ago, and I’ve made incredible progress towards my fitness goals with his support and expertise. Every workout involves different movements and activities– this not only keeps things interesting, it also keeps your body guessing– by not allowing your body to adapt to the movements or weight, the results are continuous.
More than being able to craft well tailored workouts that meet your specific fitness goals, Sergio is incredibly patient and attentive. He makes sure you maintain proper form throughout the session. He also takes body measurements at several week intervals, which allow you to track your progress in a tangible way. His concern is with complete body health. He had me keep a food diary and gave me feedback on constructing a better nutritional profile for myself. He also gave me a body weight workout routine that I could follow when I was out of the country for a couple weeks. He goes above and beyond any personal trainer I’ve ever met.
I really cannot recommend him enough. Training with Sergio is the most fun and and most immediate payoff (in terms of body composition) I’ve ever experienced working out. It’s also clear that he cares about what he does and has a genuine interest in your success– both really important characteristics in a personal trainer.

I can’t recommend Sergio and Body Matrix highly enough. I’m an avid runner, belong to Crunch, and have been doing some of their weight and spin classes for the past few years. For my birthday, I decided I wanted to make some serious changes in my workout routine, get in better overall shape, and, of course, look amazing for the summer season. I was stuck in my usual routine of tons of cardio and a few weights here and there, and not seeing the results I wanted to see, so my boyfriend suggested I look into a personal trainer. I had the usual fears – not wanting to look bulky, not loving weight lifting – but decided it was worth a shot to change things up. I asked around, and was referred to Sergio at Body Matrix by a good friend, and committed to 6 weeks of routine personal training workouts. I went into this not expecting much, and 6 weeks later I’m at 16% body fat, looking leaner and more toned than ever, lifting seriously heavy weights, and feeling stronger and happier than ever before. To say I’m a convert is a total understatement! Sergio was very motivating and inspiring, understanding my goals and worries from the start, and coaching me through every step of the way. I had a million questions about nutrition, types of workouts, and he knowledgeably addressed all my concerns with patience and promptness. I’ll admit that I’m resistant to change and can be a bit neurotic, but having committed to 6 weeks and with nothing to lose, I dutifully followed Sergio’s recommendations about limiting my running, only slightly changing my eating habits (he encourages cheat days!) and embracing lifting heavy weights (instead of the 7 lbs free weights I normally used), and I saw incredible results I never thought I could actually achieve. I couldn’t be more impressed, satisfied and grateful for the training I’ve received so far, and definitely look forward to keeping it up!

I love the boot camps! they are a really good workout. The trainers check constantly on how are you doing and the form of your body to prevent injuries.
I really enjoy my work outs here and I Highly recommend them.

Jennifer Song is a great PT: she pushes you to your limit and beyond! Everytime I work I with her I feel she utilizes all my muscles especially my core and gives it a good kicking! Her workouts are varied and you never feel like it’s the same routine. You will not be disappointed working out with her! She is tough and she whips you in shape with a smile :)!!

I have been training with Jennifer Song for almost 2 years. She is a great motivator, and pushes you to get the best results. Jen truly cares about her clients, and wants each one of them to be successful. Jen doesn’t only train, but she also helps you with nutrition. With Jen’s help, I have been seeing my waist, butt, thighs, and arms get thinner and thinner, and my strength has increased immensely as well. Overall, Jen has helped me become the person I always wanted, stronger and leaner. I would highly recommend Jen, because she isn’t only a trainer, but she also becomes a friend.

Why can’t I give Sergio 6 stars?
I started meeting with Sergio soon after I moved to SF. I was looking for a kettlebell instructor, and, as luck would have it, ended up with probably one of the top personal trainers in the city.
Sergio is extremely knowledgable and PASSIONATE about what he does. He has a genuine desire to see his clients improve not only physically, but mentally as well. There are a lot of «good» trainers, but his genuine concern for your whole body self-​improvement, and his passion for what he does, sets him apart.
Sergio constantly pushes me beyond what I thought was possible. Box jumps, pulls ups… never thought I could do them but through his encouragement (and a few threats;), I’m getting there! He doesn’t criticize or judge; instead, he guides me and encourages me… always with a smile.
I would highly recommend anyone searching for the best personal trainer to meet with Sergio. If you put in the work, he will help you get the results.

Training with Sergio
1.i’ve got the exact and quicker results.
2.i’ve learned that i can smile during workout.
3.i’ve realized that how strong and valuable person i am.

Results, Results, Results.
After research and interviews with other Personal Trainers, I selected Sergio to get me into wedding shape. I started with Sergio 10 weeks before my wedding, and within a month, I’d dropped over 5lbs and lost 1 inch of all my trouble areas (hips, thighs, waist), and was noticeably toner, stronger, and feeling way more energetic.
Working with Sergio, you never know what to expect! He mixes it up with kettle bell training, boxing, circuits — you’ll never get bored! What’s also great is his boot camp (REACTT Boot Camp), which is a nice option to combine with his Personal Training services (you know, if you’re trying to maximize your money and all).
Mind you, I’ve done other boot camps and training (women’s ones, ones that utilize rope like contraptions that hang from the ceiling), and I’ve never gotten results like this, in this short amount of time.
Sergio will get you to your goals — even if it means being real with you (we discovered through my food diary, that my entire diet consisted of carbs –oops). And being real, also means being realistic (carbs are good, just make sure they’re complex carbs, and cheat days are great days!). Definitely give him a call today!

I began working out with Body Matrix about 15 months ago. Despite the fact that I am a skier, mountain biker and former triathlete, before working out with Sergio, I had never focused on lifting with my legs or core training. The results from two one-​hour sessions a week have been astonishing. My personal records (PR) on a number of workouts have increased dramatically and my strength has increased greater than 2X in a number of areas. However, the most exhilarating thing about the results with Sergio is how I feel away from the gym. When skiing I feel like my legs are 10 years. This is why I train — to enjoy life more. I can’t imagine a better coach than Sergio.

Oh man where do I start?! I first started seeing Sergio when I was 23 (2 years ago). A few months ago, when I found out I was chosen to compete in Donald Trump’s Miss California USA pageant, I came straight back to Sergio!
It is no small feat to get a body ready to walk on a stage in a swimsuit in front of hundreds of people and TV cameras, and some of the MOST critical judges, but Sergio welcomed it confidently.
Sergio asks the right questions in order to perfectly understand your goals, and what you want to look like/​feel like ultimately. For me, I wanted to be lean and toned. Results? I am now a size 0, and more toned than I’ve ever been– not to mention more stamina than ever. AND I still have 2 more months to perfect things before my pageant!
Each training session is different and geared specifically toward you and what you want to achieve. For example, Sergio introduced me to boxing which I LOVE, so he adds that in at the end of my workout for some condensed cardio. If we start doing a specific exercise and it doesn’t feel right to me, he will immediately substitute something better so that each exercise is productive.
Just 2 months later and I have met all of my major goals by dropping fat, and gaining muscle tone. All of my measurements have decreased, as well as my weight and body fat percentage. I have referred several friends to him and they all had positive experiences as well.
I can not recommend Sergio enough! He knows what he is doing and I have personally seen the results to back it up. If you have found him, YOU are the lucky one! =)

Thanks Sergio!!!

Sergio is a great trainer! His Olympic lifting BodyFit sessions in the morning at Planet Granite is a different workout from all others. I love it! Can’t get enough of it. Not only is Sergio a genius at creating these workouts, he’s great at explaining how it relates to everyday life functional movements. He’s also great at explaining the correct form and methods of the exercise, so I don’t get hurt and maximizes the workout to the full potential. It’s the best all around exercise regiment, it’s helped my back, core, legs, and upper body strength, etc. etc etc. Thanks Sergio!

Just after getting engaged I decided it was time to work out with a personal trainer. I spent hours online doing research and decided to go with Sergio. I narrowed my choices down to a few trainers and decided on Sergio because of the positive reviews, all of which were extremely results oriented.
Signing on with Sergio was definitely the right decision. I am ~3 months in and have seen good results so far despite a ton of travel on my end interrupting our workouts. I just signed on for another couple months and am excited to see even greater results.
He pushes me really hard from the minute I walk in the door until our time is up. He also consults on my diet and takes time to email me detailed suggestions when needed. For example, when I was traveling for over a week he sent me a detailed exercise plan.

Sergio has been above and beyond what I expected when working with a personal trainer. A little bit about my history: I have been having knee problems from long distance running for over a year and notice that I need more than just rest to fix it. My chiropractor recommended I see Sergio to help improve my total body strength and stabilize my running form. I can’t thank my chiropractor enough for his recommendation. Sergio makes it a priority to tailor all the workouts specific to my needs. Not only has Sergio introduce new exercise routines to strengthen my hamstrings, calves, gluts, and core muscles, he is also determined to find out the source of my knee problems. Currently my knee have improved significantly since working with Sergio and I look forward to making more improvements with every session.

I was a member at 24 Hours Fitness when Sergio joined the team of trainers. Since I’ve been an active member of the gym, I’ve had a lot of interactions with him. Whenever I needed help with weight-​training, Sergio would patiently offer his. Over the years, I observed how he has advanced into an experienced, respectable personal trainer. I’ve witnessed results in his clients. What sets him apart from others is that he LOVES his job. Needless to mention his high level of skills and knowledge, he doesn’t just train you to be fit. He trains you to be who you are and beyond. Sergio never stops learning. We were training with Mr. Jim Lem (2004 CA Powerlifting Hall of Fame). As a teammate, I can say Sergio has displayed ultimate respect and support for his teacher and teammates. His skill level can only get better.
Sergio’s biggest muscle is not on him, but in his heart! This is what you look for in a personal trainer. Contact him for life-​changing experience. You won’t be disappointed.

I have been working professionally with Sergio Ruiz for the past two years and have nothing but great things to say about this well educated health and fitness professional. As a former athlete himself, he knows the demands that are put on the human body whether the individual be a competitive athlete, weekend warrior, or someone trying to stay fit. Through his extensive education he has multiple areas of specialty that enables him to effectively assist individuals of all ages and skill achieve a higher level of fitness.
I have sent many patients to Sergio for specific strengthening and/​or rehabilitation and have been very pleased with the positive results. It is my strong belief that in order for anyone to completely recover from any injury a combination of therapy, rehabilitation, and strengthening must be implemented. As a chiropractor myself I can say that Sergio can pick up where I leave off. In that sense we work towards the greater good of the patient/​client in hope he or she will MOVE FORWARD and return to the sport or activity which is their passion.

I’ve really enjoyed training with Sergio. I’ve been training with him for the past 2 years, off and on. I’ve left every session energized and inspired to eat more healthy and exercise more regularly. The workouts he plans for me are well-​thought out for my skill level. He watches every movement carefully to make sure I’m executing each exercise with good form. As a result I’m always challenged to a level of difficulty that’s never beyond my capacity.
I’ve worked out with other trainers, and none of them compare. Either the direction was mediocre (she just wasn’t very knowledgeable), or the trainer was constantly distracted by other people at the gym (too many hot bods @ 24Hour?). Sergio pays attention and notices when I have tightness in certain areas. He’s shown me different stretches to work on better flexibilty, the key to doing a greater variety of exercises. He plans different exercises to keep the muscle groups guessing and working each time. It makes each session interesting and invigorating when I feel I’ve accomplished something new every week.
I love working out at Perfect Fit. The space is like someone’s home — a private gym with everything you need. Well, except a shower, but that’s not essential. It’s an intimate space, but I never feel like we have to wait for a machine or weights. We’ve shared the gym space with at most 2 other trainers and their clients, and it’s never felt crowded. Oh, and I’m so tired of seeing people throw around gym benches/​weights like it’s a piece of crap. I notice Sergio is very respectful of the equipment, and that speaks volumes to me about the detail he spends on my training.
When I tell my friends I’ve done dead lifts and trained with kettle bells, they don’t believe a girl could do any of that. Thanks, Sergio! For giving me fodder for boasting! I know this sounds like a commercial, but I have nothing to complain about someone who works so hard to make sure I get closer to my workout goal.

I think the guy David who wrote the review below probably sat on his couch daily eating junk food and then wrote the review wondering why Sergio didn’t make him fit! Sergio is amazing and being that he has been my trainer for over a year now I think I would know. I have lost 30 pounds and toned up tremendously. He has changed my work out to accomodate each fitness level I would reach where as most trainers do the same routine with each client.
If you want to see results and are willing to work for them, Sergio is the one trainer in the city that will help you achieve your goals.
