I have been going for some kind of fitness training for almost 40 years. Most trainers talk a good game, but then rely on the same template trainers use from coast to coast. There is no such thing as "one size fits all," educators be damned. Cookie cutter homogeny is not what I am looking for. Sonja, the owner of Demco and one of the trainers, customizes my workout to me, my size, and what I need to be fit. She isn't judgmental, shunning "silver sneaker" exercises in spite of my age. Sonja gets that 99% of us older cats still want lean muscle mass and strength. Sure balance and flexibility are important, and we do some innovative work on these two vital aspects of physical fitness. Yet, there is no condensation, her workout also develops my body. I am beginning to look and feel better. Sonja knows her stuff, and she is a unique professional, existing amongst a forest of trainers who can only follow a prescribed text, chapter by chapter. read more

I generally need to be forced into a gym and to work out, but working out with Sonja is a game changer! She encourages me, while at the same time holding me accountable to my commitments. The positive environment creates a space where I can get personal attention and the best individualized work out for my personal needs. I work out consistently now because Sonja pushes me to reach goals I did not even know I could reach! Somehow, she makes it fun to work and push myself harder than I think I can. I cannot recommend her enough! read more

I have worked with Sonja at Demco fitness for a year and have noticed a dramatic change in my strength and body composition. I truly appreciate how attentive she is to my specific needs - as a former collegiate basketball player, I enjoy being challenged and Sonja provides a welcoming space for me to pursue my goals. I highly recommend Sonja and Demco Fitness for all ages and fitness abilities. read more

Sonja is amazing! I worked out with personal trainers 1:1 in the past and also tried going to the gym to work out on my own but Sonja created a great mix of the two. Personal training sessions can become very expensive quickly, especially if you are doing it on the regular basis. Working out on your own is definitely cheaper but I could never find motivation to do it consistently. I'd go for a couple of months and then stop. Sonja's workouts are created for each person individually and you end up doing a completely different routine from the other 3-5 people, who work out at the same time as you do. You are still getting an individual approach and motivation from Sonja but you have other people who work out with you at the same time. Sonja does a great job keeping an eye on everyone working out at the same time. I really enjoy these workouts! read more

Demco Fitness - Trainers Near Me - Seattle, Washington

A year and a half later doing semi-private training at Demco Fitness and I could probably write a five-page essay on how much I love this place but I'll try to keep my focus. I'd done private training in the past, still wanted the programming (i.e. my workouts mapped out for me), but didn't feel the need for 1:1 training, so the semi-private option was perfect for me. It's normally ~5 of us in the gym at a time each working on our own program with the supervision of one trainer. I love the personal attention Sonja (the owner) gives to programming. The exercises/sets/reps I'm doing are completely tailored to my goals. Each program is 4 weeks long so I never get bored. And if I change my goals month to month, I let her know and she adjusts. For example, when I decided to run a half marathon, she customized my program to cater to running. Timing-wise, there are lots of options, 7 days a week. I normally go early mornings and workout with Sonja. I can't tell you how many times I've said "Sonja, I don't think I can do that" and she encourages me to prove myself otherwise. Her passion, attention to detail, and knowledge has been the foundation for me to improve my strength, form, and overall wellbeing. Even when I go outside of my normal schedule, I have the utmost trust in the other trainers - Conor, Selina, and Zach are all high-caliber trainers that each bring their own incredible energy and knowledge base to the gym. I know whenever I walk into Demco Fitness that I'll be in good hands. Whether you're there to get a sweat on, hit a lifting goal, nurse an injury, or run a marathon, you're in the right place. But it's more than just a gym. It's a community of supportive, welcoming, hilarious people, not to mention killer music and the occasional neighborhood dog that stops by the door to say hello. read more

I started working with Sonja about two years ago. I'm 70 years old. My goal was to build upper arm strength and make sure I was steady on my feet. I did Sonja's intensive introduction course and then continued on for about a year and a half. Sonja is awesome. Her instincts are excellent with regard to the type of exercise I needed and how to make adjustments. Today I've got my own routine and go to my gym three times a week for a shorter workout. And I feel great. You can even feel the muscles in my arms, which I never had before. I highly recommend Sonja's program. For someone like me who was never interested in weight training before, Sonja was the perfect solution. I looked forward to going to the gym with her and still do. I will be forever grateful for her guidance. Is it intimidating for a 70 year old woman to join a gym with a bunch of young people? A little. But in the end, I was hoping that I could inspire them. You're never to old to learn how to take care of your body. Thank you, Sonja. read more

Dropped in on a class a couple weeks ago and couldn't believe the positive energy in the group class. Didn't even feel like a workout until I finished and felt the burn. Perfect place to tone up before the summer! read more

My wife and I have been going to Demco for a year now. It's been a great fitness journey so far, we take the semi private group sessions where each of our workouts is programmed for our needs. Since starting both of us have seen significant gains in strength and fitness. The trainers here are all very professional and keep a healthy balance between pushing us to do our best, but making sure we execute the forms safely and within our limits. Thank you Demco for all you have done for us, we are always looking forward to our next training session! read more

I have been going to Demco fitness for 6 months now. The gym is very well equipped and most importantly the vibe there is very friendly. Sonja and Ro are amazing trainers and the monthly programs created by Sonja are personalized and focus on overall development and growth. I had an ongoing injury and my program was curated to help with it and get stronger in those muscle groups apart from other exercises. The results are amazing. I never get bored because every month there is a new program and a great mix of exercises and the trainers keep an eye on your form and movements and correct and modify according to your needs. I didn't do any weight training before but in these 6 months I have become stronger and I am able to lift and work with weights. Going to Demco fitness is the best part of my day because of the community feeling and all the fun I have along with a good sweat. Highly recommend! read more

Looking for your abs? You can find them at Demco Fitness. Sonja is a great instructor whose personal approach to training helps everyone to achieve their respective goals. read more

TL;DR - I've been working with Sonja for 2 months, and I already feel stronger and more energetic. Sonja is incredible to work with. Most importantly - I'm excited to come back for each session, because Sonja is constantly keeping things interesting with new movements and combinations. She knows how to push me and hype me without pushing too far, which to me is the MOST important quality in a trainer. She's fantastic at making real time adjustments and pivots when my body is feeling unstable or sore. Bonus - the gym soundtrack is always dope! Final note: I'm one of the rare clients who found Sonja just by googling. 99% of her clients come from referrals, which is such a credit to her skills as a trainer. Not to mention, she builds a real community! Even though I wasn't connected to her gym at all on day 1, she's introduced me to everyone I cross paths with in the gym (including her adorable dogs). If you're looking for a trainer, you absolutely should give Sonja and Demco Fitness a try. read more

Demco fitness is awesome! I've never had a personal trainer before and I'm proud to say I've been with Demco Fitness for 8 months now! I've never felt better. Sonja motivates and encourages me more than any other person I know. She definitely has a passion for fitness and the Demco family she's built. I've committed to 4 days a week with her and I never thought I'd gain the strength I have or put on the 10 lbs of muscle. Putting on weight has always been a challenge for me. The things I like most about working with Sonja is each session is different and designed to fit my personal needs/goals. Every session is challenging but FUN! She works hard to staying up on new techniques that show great results. She really gets to know you inside and outside the gym. I look forward to every workout with her. She's has helped me change my life and I couldn't have been blessed with a better trainer. read more

I have been going to this gym for a few months now and it is by far my favorite gym I have ever joined. There is a real sense of community and you don't get that weird LA fitness vibe where everyone is weirdly into themselves. Sonja by far is the best part. She takes a lot of time and thoughtfulness in building a plan personally for your needs. I have a really bad back and she has been very meticulous on building a plan that not only protects my back but works to strengthen it as well so I can advance my fitness goals. She has also really helped me rethink how I think and eat my food, and I LOVE to eat. If you communicate your needs and goals, Sonja will do everything in her power to give you the guidance and support you need. She also does an amazing job at creating a community within the gym. She is hilarious and a great people person. This place is definitely worth checking out! read more

I have been training at Demco for over 6 months and it's totally changed my perception on fitness, strength, and my own abilities to get stronger and achieve my goals. I was really freaked out by "heavy weights" when I first came to Sonja thinking they would make me bulk and look like a Cross fitter (no offense cross fitters). Sonja built a plan for me that was super challenging, worked on my problem areas, and had so much variety that I was never ever bored in her gym. It has grown to be one of my favorite hobbies and something I really look forward to 3x per week. If you want to be challenged, get stronger, and hang out with some really awesome people - the environment is part of what makes it so good - I highly recommend Demco Fitness. read more

I've been training at Sonja's gym for almost a year and I'm without question in the best shape of my life right now. I've always been one to workout at home or in private because I'm not a big guy and gyms are intimidating but there's such a great feeling of community in her gym that it instantly felt comfortable. She has tailored my program to my specific goals and has helped me feel stronger and more confident than ever. If you want to feel good and be a part of a community with a highly skilled trainer, you should swing by and hang out (there are bars, ropes, and rings, take your pick. read more

This place is worth every penny. I've been going to the semi-personal classes for over a year now and I'm stronger than I've ever been. When I first started, I was a gym newbie. I had zero body strength. Sonja's training (the owner) is so good that I can now actually do a pull-up! Her classes are welcoming to all people and all fitness levels. Sonja is a very knowledgeable trainer and she creates a custom program each month tailored to your body and goals. This is really nice because the workout is different each day and I don't get bored of it. Sonja's programming is effective - you know you're going get results. No cookie cutter workouts here! During the workouts, Sonja and her trainers make sure you that do the exercises with proper form and continue to modify your program based on how your body feels during the workouts. She's the real deal guys. The bootcamp/hiit classes are pretty good too. Every class is different which makes it fun and challenging each time. I highly recommend checking this place out! read more

I've been training with Sonja at demo Fitness for the past two years and for the first time ever I have found a gym that is perfect for me. Sonja always provides the right balance of pushing me forward while also taking into my body's specific issues/needs. When I need a modification for my knee, Sonja is quick to find 3 or 4 alternatives right off the top of her head. I can't recommend Demo Fitness enough! read more

Demco Fitness is the best gym that I have worked out at! I've been a Demco loyalist for over 2.5 years now. Demco is much more than a traditional gym. Sonja and team will provide you with customized routines to suit your fitness needs and regimen. Second, you will get the personal attention you need from the best trainers due to the small class size for in-person sessions; and lastly, access to a great community of fitness enthusiasts. Especially during the pandemic, the team at Demco has gone above and beyond to move the workouts online and provide equipment and routines to work out at home. If you're the type of person who prefers to workout at the gym but are apprehensive of maintaining social distancing then Demco is for you. Owing to the same class size, you can be assured of your own space. The gym is equipped with sanitizing sprays/ wipes and the community does a fantastic job of looking out for each other by wiping the equipment down after every use. In addition, Sonja will post monthly/ weekly challenges to keep us motivated towards our goals. Thanks to the Demco team, I'm the best I've ever looked! read more

Sonja Demco is an exceptional trainer. Not only she genuinely cares and works hard for you, designing programs around your personal needs and challenges, but she's also very fun to be around. She somehow makes working out something you look forward to, even if you hate the effort it takes. If you're looking for motivation and quality training, she's hard to beat. read more

I have no doubt Sonja is the best trainer you'll find in Seattle. She takes into account your fitness level, injuries and goals and creates a monthly program specific for you. Each new program builds on the previous month's and it's amazing to track your progression and see how far you've come. She genuinely cares about her clients and their health and puts an inordinate amount of effort into ensuring their success. Beyond killer workouts (and my butt never looking better), she has created a community in the gym that makes getting up to workout at 6AM something I look forward to. read more

I originally found Sonja because her first gym was within crawling distance from my apartment, and that's the kind of accountability I needed at the time. Since, she has expanded to her own amazing space in Belltown, but the 10 minute drive is no deterrent - I am hooked! I have learned so much about exercise, my body, and overall health since working with Sonja over the last 10 months. Every work out is challenging, and she listens to my goals and makes them part of my plan. Her approach is holistic, and she understands that in order to live life, you need balance. I'm never afraid to tell her about the awesome new restaurant I tried (or the cocktail pairing I had with dinner), even though I am counting macros and working on a food plan with her. I've seen amazing results in weight loss, increased strength, and stamina. The community that she has created around her gym is energizing and engaging. We work hard, have lots of laughs, and make progress. She is very flexible and cares about her clients in and out of the gym. read more

Also, it's a fun environment and I really looked forward to going to the gym everyday. read more

10-STARS!!!! Are you tired of being tired? Tired of wasting your time & money on programs that simply are not getting you the results you want? Then you need to train with Sonja Demco at Demco Fitness! I am a fitness instructor that has been in the fitness biz for 25 yrs & have had many trainers in my time but NONE have ever trained me the way Sonja does. Here's why... +NASM certified personal trainer +no workout is ever the same! +innovative, outside of the box training that keeps you engaged every session +proper form & execution is enforced on every exercise to prevent any injuries +core strength is the basis for the entire workout +group training sessions that foster community & support +more than affordable (1-monthly fee for unlimited sessions) +easy online booking tool +guaranteed results in 90-days -- there's no other way with the way she trains!

By FAR the best training I've ever done - and I've tried a lot of places and trainers! I've worked out at Demco Fitness for nearly two years. The trainers are amazing, they all have great attention to detail without ever being too much in your bubble. I love the community as well - didn't expect to make the friends and connections I have! read more

I've worked with a variety of personal trainers before, but none motivated me stick with it consistently as much as at Demco Fitness. Sonja truly works hard to provide you with a personalized, long term fitness program. She creates a schedule for each of her clients with all the exercises to do over several weeks, walks you through all of them as you go, and can explain why each routine is important. After working with Sonja for about a year, I've noticed a huge improvement in my fitness that's helped me to do things such as bike from Seattle to Portland and spend 40+ days skiing this past winter. I also found semi-personal training to be much more fun than just having one person watch you do all your reps for the full hour. You get to work out with a few other people all doing their own programs, and Sonja is still always there to help you out and push you further. If you're really nervous about working out with other people at first, you can always book a few private sessions to start out. I highly recommend Demco Fitness and am really sad I have to find a new gym when I move. read more

Sonja is super super inspiring. Strong recommended. I've been here for several months and I could feel my change. Not only about losing weight, growing muscles, being stronger, I could also feel that my life is being more health. read more

I have been working out at demco fitness now for almost a year and I just have to say how much I love it. When I first started, I was uncoordinated and did not know how to strength train beyond working out on machines. I also had back pain due to my career as a dental hygienist. The trainers here are so personable and hilarious that being so new to strength training did not feel uncomfortable. I no longer have back pain and I have more results than I have ever had working out alone. Also, the people that work out here are the best! I have made some great friends here. I highly recommend this place! read more

I have been working out at Demco for 2 months now and for someone who can't stick to a trainer/ plan, this is great and shows how awesome a place it is. Sonia is an amazing, knowledgeable trainer who helps everyone reach their personal goals but most importantly teaches healthy lifestyle. I highly recommend this to anyone who wants a sustainable, wholistic healthy living. read more

Sonja is the best trainer I have ever had. She designs a custom program and provides nutritional guidance for each client based on their needs and goals. Sonja is knowledgeable in her field and is a patient teacher. The people and community at Demco Fitness makes working out so much more enjoyable! The new location is beautifully done and truly unique! read more

by far the best trainer(s) in Seattle. helped me train and complete a marathon and gives me the confidence I need on my health journey. you are missing out if you are not training (one on one, semi private, group - they do it all) with DEMCO team!! read more

Sonja -- the one-woman machine behind Demco Fitness -- is a rare find in the fitness world: She's a trainer with a deep, holistic understanding of fitness who can (and does) help anyone on the spectrum between a peak athlete and a total beginner looking to be healthier. Sonja offers personal and small-group sessions, and she's skilled at coaching groups or multiple people at once: just when you think she's focused on someone else and isn't looking at you, she'll shout out a correction on your plank form or squat technique. She's attentive, constructive, and deeply knowledgable. Indeed, it's her deep knowledge of fitness (and her ability to convey it to her clients) that makes her so valuable: With every piece of advice or instruction, Sonja reveals a true understanding of physiology, proper form, and holistic fitness. This means she can help experienced lifters fine-tune their form, but can also get newbies doing great functional exercises (like deadlifts, squats, and kettlebell swings) correctly, safely, and effectively. Forget the dude with the tank top at your local 24-hour fitness who has you doing curls and triceps extensions -- Sonja will have you doing exercises that will make you functionally fit, give you a stronger core, and increase your mobility. Finally, as anyone who's ever worked out in a gym, big or small, knows, the culture and vibe are important -- simply put, you're more likely to go to the gym when you have fun there. That's the case at Demco. The ambience of Sonja's gym reflects her personality and attitude toward fitness: it's upbeat, intimate, and friendly, but not frivolous: it's a place where you get the most out of the time you have, and leave with a good sweat and a surge of endorphins. read more

Sonja is an amazing trainer. She makes everyone laugh and allows space for people to be themselves. Her deep understanding of the body and fitness as a whole is admirable. As a yoga teacher myself, I love when I meet people who put in the time to really know their work, be passionate about it, and make it accessible to every person. If you want to get healthier, find community, and laugh while doing... Sonja is your girl and Demco Fitness is where its at! read more

Sonja is absolutely amazing. I love her style of training, her sense of humor and her commitment to giving her clients the workout and results they desire. The atmosphere at Demco is extremely welcoming and nonjudgmental and I highly recommend Sonja's system for those who are new to fitness and those who are more experienced. read more

I have been a member of Demco Fitness since the summer of 2021. I, personally, need accountability to be consistent in doing a work out routine. A couple, I know, highly recommended this establishment to me as they had been going for quite awhile. At that time, I was also having pain in my left knee which continued even after PT. This couple also explained how the Instructors are very skilled in working around injuries, although, it turned out my pain was caused by arthritis. Well, I no longer have pain and my knee is stronger. Demco is semi personal training, in that, it's a small group of people and each person has their own unique exercise plan depending on where they are at physically. If our form is incorrect, we are instructed on the proper way to execute it. The instructors are encouraging. We are all there for different reasons but getting healthy and stronger is all part of it. We, includes all age groups and all fitness levels. It works. No matter what age or fitness level, you will see results with consistency. I am turning 70 in a month and I have never had such muscular arms. I'm strong. I'm proud of myself and grateful to all the instructors who help me to achieve my goals. Sonja, who is the owner, is fun, extremely knowledgeable and kicks butt!! I wouldn't hesitate to recommend Demco Fitness. It's fantastic!! read more

I was introduced to Demco Fitness by a friend after Covid-19 hit. I was desperately trying to find a program to maintain my fitness schedule while my gym was closed. These Zoom and live-streaming classes are the best I've ever had! So good I am not even going back to my old gym. They are fun, flexible for all fitness levels, challenging and varied. Demco has helped me up my fitness level even during quarantine. As a bonus, their music slaps. read more

I have always been someone that loves exercise, group classes or anything getting people together and moving, but I hit a wall of boredom and lack of motivation earlier this year, and that's when I found Sonja and her gym. I cannot recommend her enough and would give it 10 stars if I could! In a short amount of time I'm excited again to exercise, have learned how to properly do exercises I have been doing wrong for years and have a great time when I'm at her gym. It's a fun atmosphere but you still get personalized attention. And there are fun group classes too! read more

I come all the way from Bothell to Seattle everyday just to work out with Sonja. I have so much fun working out with her and she treats everyone like her family. read more
