before meeting Demetrios, I basically NEVER worked out in a gym. I was too scared. I was consistent but only in my apartment. 6 months in, and I'm now the person who doesn't miss a day in the gym. I'm becoming leaner, stronger, and fitter than I've ever been and i couldn't be more grateful for my unwavering rock of support--Demetrios. He goes above and beyond for his clients. in addition to my newfound consistency, his belief in me has inspired me to dream bigger and take my next steps steps in seeing what's possible for me in my fitness journey. of course, we all ultimately need to take full responsibility for achieving our desired results. But the expertise, accountability, support, role modeling, and genuine kindness, of someone as fit and experienced as Demetrios? that is priceless. if you want to level up, I highly recommend upgrading your life with a Demetrios. read more

Demetrios has trained me now for 7 months, approximately once weekly since March, and we'll continue. We train for a mix of mobility, strength, and core. What distinguishes Demetrios from many trainers is: - he can quickly (within probably one session) see where you may have shortfalls that you may or may not(!) be aware of, and structure your program/exercises to partly focus on those; - depth of knowledge, partly from academic degree; for example detailed anatomy, kinds of exercises and how they impact different goals; - every session is intense and comprehensive, because that's my style and Demetrios knows how to match yours; - easily and with short notice adapts sessions if you sustained a limited injury a few days prior; - last but not least, a fun guy to hang around with a sense of humor. Whether or not you are actually considering personal training, I highly recommend trying a session with Demetrios if only to see shortfalls you didn't even know about. And for your physical fitness you can't go wrong by working with him consistently. read more

Demetrios is an AMAZING trainer! I was nervous to start training (or to even step foot in the gym), but Demetrios immediately made me feel comfortable and at ease. His training, knowledge and experience in the health and fitness field is extensive, comprehensive and unparalleled. This unique background enables him to tailor workouts that are highly effective, goal specific, and safe. Demetrios makes your workouts challenging and varied, while being conscious of injuries, fitness level, and personal preferences. Each session is customized to my personal fitness goals and progress, and he often switches up the exercises to keep it interesting and effective. I appreciate the combination of strength, agility, balance and cardio in our workouts and in a short period of time, I've improved in all of these areas. He is inspiring, motivating, and supportive. He pushes me to work hard in our sessions, without ever pushing me past my breaking point. This approach allows me to leave our sessions motivated to return again. Demetrios is also very reliable -- he has never missed or been late to a session -- which works well for those with busy schedules. On top of all this, Demetrios is just an amazing person. He is approachable, thoughtful and funny. He has an upbeat and positive attitude that is truly infectious. If I could give him more than 5 stars, I certainly would! read more

Demetrios is fantastic! I've been working with him on strength and muscle endurance training for the past 5 months, and I've seen steady progress. He's extremely knowledgeable and has a variation for any kind of situation, esp if there's some kind of pre-existing injury. And it's not just basic lifting and such, he does a great job incorporating all kinds of full body functional movements, which is great when I have a little less time than the usual session length. Most importantly, he's funny, caring and just really fun to be around. read more

Fantastic. Pushes you. Responsive to unique desires and circumstances. Great guy. Highly recommended!

What a great experience I had working out with this amazing trainer! I had problems with my lower back and after a couple sessions of stretching with him it's finally gone! Can not express how happy I am. Demetrios has the nicest personality, he is funny and a professional at the same time. Highly recommend! read more

Demetrios is a fantastic trainer. He is extremely knowledgeable, thorough and diligent about creating a full spectrum plan, in concert with your physicians, to improve your quality of life. I suffered a very serious injury back in 2001 and Demetrios worked with me to get me back in superb shape over the course of a few years. Fellow Yelpers, he is one of the best in the business. He is a nice guy with a wealth of patience, expertise, and long term follow through. He continues to check on me once in a while to monitor my long term health...without soliciting any business! How about that! So I thought I should write this long overdue review. He worked with me to get me back into top physical shape and was worth every penny and every long, challenging hourly session :) read more

Demetrios is the most effective trainer I have worked with. His knowledge of the human body is simply amazing and makes me pay attention to every instruction during sessions, but also gives me reason to follow my program between sessions. Thank you Demetrios! read more

Demetrios is hands down the best trainer in San Francisco. He has a wealth of knowledge in functional strength training, mobility, core, flexibility and other areas. He can diagnose exactly what style of training you need based on your goals and helps you hit them fast. Also unlike a lot of trainers, he's a pleasure to be around. Makes those tough workouts more enjoyable. I'd recommend Demetrios to anybody looking for a great trainer. read more

I've been working with Demetrios twice a week for about 9 months in a small, private gym in my building and I couldn't be more satisfied. As compared to when I started, I'm much fitter, stronger, and confident with my body, which has carried over into my taking better care of myself (diet and exercise) on non-training days, and has redefined my sense of my boundaries. I've also lowered my overall cholesterol level nearly 35%, as well as my blood pressure, and by every measurement I'm healthier without any reliance upon medications. I appreciate that Demetrios varies my workouts consistently and has gradually challenged me to improve my performance, while taking care to ensure that my progress doesn't induce injury and follows from his careful assessment of how I respond each session, rather than, at times, my impatience. Highly recommended. read more

Demetrios is an amazing trainer who delivers great results. He is a trainer who can accomodate all types of individuals and sports training. He will come to your home, workout outdoors with you or at the Sports Club LA if you are a member. I've worked out with Demetrios on and off for several years and have achieved superlative results. These results not only include increased overall conditioning but also rehab benefits such as core strengthening which alleviated my back pain. read more

I've done about a dozen workouts with Demetrios and can say that with every workout, I've been more and more impressed. I have been an athlete since very young and have always worked out and been in competitive sports. As I'm approaching 40 years old and not having the same drive I once had due to age and injuries I decided to search for a trainer. I wanted to find someone who was highly skilled with many years experience and also an athlete. I'm glad I found Demetrios, since training with him, I have had remarkable strength gains, body fat is down and he has helped me with flexibility which has always been a major issue with me. Can't go wrong with this dude! read more

I started working with Demetrios after I sustained a pretty bad lower back injury and was looking to get back into working out. I have always been an athlete and was really worried I would never get back to normal. Demetrios took the time to learn exactly what my injury was and build from the ground up. It started with stretches and light core workouts and eventually developed to feeling even more fit than I was before my injury! He is extremely creative with all of his workouts and the modifications we do to accommodate my healing back. He is a master of core workouts which has not only helped my back feel way better, but really has toned me up. On top of the high energy he brings to every session, Demetrios is extremely educated in his craft and is very vocal about what muscles are being worked on and why we are doing certain excercises. I have worked with a number of trainers but can say with 100% certainty that you don't run the risk of being hurt by overworking. He pushes you hard but is very aware of where each of his clients' limitations are. Working with D has literally changed my life. I went from months of being sidelined and unable to do basic tasks - to lifting the heaviest I ever have, having the best endurance in along time, to being as tone and cut as I was during my prime state. On top of everything, he is a genuinely nice guy and someone I am happy to call a friend. I cannot recommend him enough. read more

Demetrios is an awesome personal trainer! I try to work out with him 3 times a week at The Sports Club LA. I also attend his group abs class on Monday nights (nothing but abs for 30 minutes). Demetrios always introduces new exercises to keep the workouts interesting. And he also helped me recover from a hip injury in time for me to run the Chicago marathon last year. read more

Now in my early 40s but I can confidently say that I'm in the BEST shape of my life simply because Demetrios is my trainer. It's never the same routine; in every training session there's always one or two new exercises to keep me challenged. I enjoy the combination of a good workout routine (circuit...as he calls it) mixed with sports type exercise movements. So if you're looking to gain strength, flexibility, tone, definition, and simply being happy with yourself and feeling good and alive after a workout....Demetrios is the guy! read more

Demetrios is the elite of the elite in personal training. He is highly professional-he knows what to do and how to do it gracefully. He is an absolute gentleman, gracious, generous and patient. Demetrios accurately evaluates your current state of fitness and designs a safe, flexible and thorough program to develop your potential while building your confidence and strength at the right pace. I have trained with him for about 3 years including rehab and strengthening after an unrelated rotator cuff injury. He was extremely knowledgeable and patient through the slow rehab and later stages. Unequivocal 5 Star trainer. read more

I had an opportunity to train with Demetrios - I am not a gym goer and was a bit nervous about it but he made the entire experience relaxed, highly informative and fun. He's professional, and clearly and expert in physical fitness. I would highly recommend him to anyone regardless of their personal fitness level. With Demetrios you get the very best. read more

I met Demetrios years ago and knew him for a while before I ever finally decided to get some training guidance from him. Before I trained with him, my routine consisted mostly of cardio and just a little toning with my own body weight and I thought I was "fit". When Demetrios showed me what I should add to my regimen I couldn't believe the difference it made in my fitness routine. I am very picky and don't like wasting my time unless something really works and his knowledge was invaluable! He tailored my workout to meet my specific needs and personal goals. He is an excellent listener and really cares. When I told him I didn't like traditional sit ups because of the strain it put on my shoulders, he gave me a few very effective (in my opinion even more effective) alternatives that caused no strain on my shoulders, and after that I loved working on my core! I loved them so much I shared them with friends and they all use the same exercises regularly as well. His energy is infectious and he has a wonderful demeanor and personality. Demetrios !!!! read more

I've been training with Demetrios intermittently for the past year and it's been great for me. I've lost 20+ pounds and he's shown me how to keep them off easily. I'm also looking and feeling more toned than I have in years. When I started with him I had intense lower back pain and now, through his abs training, it hardly bothers me. He's also just a fun and nice guy. read more

I've trained with Demetrios for more than 10 years. Over that time he has continued to make workouts interesting and to push me to reach new goals. He has a great understanding of anatomy and exercise physiology and has always tailored my workouts to a very holistic combination of strength, balance, and cardiovascular fitness, allowing me to capitalize on gains and adjust workouts to avoid injury. The level of dedication that Demetrios brings to his career as a trainer really is inspiring, and is one of the reasons why I have continued to work with him. He has a great personality, is both caring and tough, and is thoroughly reliable. I leave our sessions every week feeling both exhausted and refreshed. Really, I couldn't ask for a better trainer, and am happy to give him the highest possible recommendation. read more

So you want to be fit? You have to change your life. You have to take it seriously. You have to keep doing the right things, consistently. Resolutions are easy to make.
