“So, I am not a gym person, but this place definitely converted me! I am amazed at how I now feel healthier and stronger after only being with Flash Fitness over a few months! This for me, is the best space in town when you want not only a fit and joyful exercise regime, but aiming also for longevity! I would recommend you to try it, and then see if it works for you- which I think it would! Many people keep coming back to this gym. Why?  Because the coach/trainers know what they're doing! They have been in this industry of fitness and health for so many years!

In this gym, I met so many wonderful, genuine, and humble people. I also met people who have been with this gym for over 10 years!  This is a testament to how good the trainers are and how amazing the community is.  I hope you will give this gym a try. It could change your life and help you find access to an amazing joy that comes when one feels healthy and alive! :)”

“Unfortunately I can't attend Flash anymore as I have moved too far away 😭 But I miss Jeff, Rita, the community and their amazing workouts every time I exercise by myself! I am a person who is a little apprehensive about working out and joining large group fitness classes, especially those where it seems everyone is an 'influencer'! Flash Fitness is a wonderful community full of kind, supportive, down-to-earth people - this attitude is led by the coaches Jeff and Rita, who model meeting everyone where they are in terms of fitness and pushing you (gently, if necessary) to your personal next level.

The workouts seem simple but really work, and the personalised nutrition/supplements advice is also invaluable. Highly recommend Flash Fitness... I just wish it was around the corner again!”

 

Tasara

Joining Flash Fitness Bangkok was one of the best decisions I’ve ever made for my health. I’ve spent years trying different workout programs but never saw the kind of results I wanted, until now.

In just 6 weeks, I saw a complete transformation. The training is smart, efficient, and designed to push you past your limits without wasting time. Jeff is a wonderful trainer, his fitness knowledge is unbeatable, and he knows exactly how to guide, motivate, and adjust workouts to get the best out of you.

What surprised me most wasn’t just the physical changes, but also the confidence and discipline I’ve gained. I look forward to every session because I know I’m going to walk out feeling stronger, leaner, and more energized.

If you’re serious about making a change, Flash Fitness Bangkok is the place that will get you there.”

 

Shams  

“I hate gym workouts. I have no motivation for it. So who can help me get the body and fitness I want? Flash Fitness! Fast and focused with results. You only have to turn up. Members have been there for over 10+ years and I can see why. Finally a place that understands me. Dad jokes by Jeff are an added bonus.”

 

Nueng

 “Let me introduce myself first. I'm 57 years old and have never exercised before. However, since my child went to study abroad, I have a lot of free time. So, I looked for a gym near home. There are many places, but I decided to choose the smallest gym. After talking to Ritah, the first day I arrived, I felt very nervous because I didn't know anyone. I asked other people if they had worked out here before. It turns out that everyone had been working out here for at least 5 years. Oh my god! How long is that? From that day until today, I have received the answer that if you are looking for a warm workout, not too strenuous, doing what you can, taking breaks whenever you want, trainers who don't pressure you and encourage you, and friends who work out with you are lovely, kind, don't bully you, and are ready to help you. Come and try this place. Just like me, I have fallen in love with exercising. Thank you very much, Jeff and Rita.”

“A Life-Changing journey  Since I joined in 2014

 I’ve been a proud member of Flash Fitness Bangkok since 2014, and I can honestly say it has transformed my life in every way- physically, mentally, and professionally.

 This isn’t just a gym. It’s a powerful fitness community built on support, motivation, and excellence. The instructors are phenomenal- knowledgeable, passionate, and genuinely invested in your progress. Their guidance has helped me stay fit for competitive sports, maintain peak performance, and feel confident in both body and mind.

But what truly sets Flash Fitness apart is the community. The members here are inspiring, driven, and incredibly supportive. Whether you're pushing through a tough workout or celebrating a personal milestone, you're never alone. That energy has kept me going for over a decade and has played a huge role in my professional success- helping me lead with strength, clarity, and confidence.

 

Flash Fitness Bangkok is more than a gym- it’s a lifestyle, a family, and a place where transformation happens every day.”

 

Plern

“I have been working out at Flash Fitness for more than two years. It changed my both body and mental health get better. Jeff and Ritah (trainer and gym's owner) are very nice. They train and help me a lot to have a correct posture. Flash Fitness is not only gym but it is also good community. Thanks a lot to make me have a better shape.”

 

Seb

“Jeff and Rita are two very attentive and friendly coaches. They adapt the exercises to your abilities. I used to get injured all the time, but since I've been at Flash Fitness, I haven't had any injuries. The follow-up is great. The coaches are always very available. I recommend them 100%.”

 

Mickey

“Perfect place to go if you want new body, better health in 30 min a day, 3 times a week. Very happy to join their sessions. Also great community.”

 

Trev A.

“I’ve never been a gym person in my life - even when I did go, I never had the confidence that I could achieve significant results. Last year my health declined and it became apparent that I needed to invest time to improve my health. That’s when I took up the 8 week challenge at Flash. There were times when I struggled but Jeff was able to suggest alternative exercises so I could continue my workouts. Jeff and Ritah put a lot of effort to make the workouts fun and challenging and after just 8 weeks I had leg muscles which looked and felt incredible. I could now move and be a lot more explosive when playing sports. The community who are here may be small but there is a lot of camaraderie and encouragement to do the same workouts and be part of the collective.

Come here to Flash Fitness if you want results and achieve your fitness goals!”

 

Phil N.

“Completely worth the effort.  Completely worth the sum of money.

“I’ve been training with Jeff and Ritah for 2months and the progress I’ve made has been incredible. Not only have I seen significant improvements in my physical health, weight and strength, but my overall well-being has also improved dramatically.

 

Every session is well-structured, pushing me just the right amount while always focusing on proper form and safety.

I truly appreciate the support, encouragement, and consistency.

I am not a gym person and used to avoid it but now i’m looking forward to the sessions.

Thank you Jeff and Ritah 🙏🏻 for the great gym experience!

I am so glad that I found Flash Fitness!🤗

Best fitness in Bangkok, I highly recommend to anyone serious about making a positive change in their fitness journey!”

 

Jo M

“Working out at Flash Fitness has been one of my favourite fitness related experiences. Jeff and Ritah are knowledgeable and helpful. The sessions are short, intense, fun and ever-changing. It is a nice little community as well. Jeff, takes the time to explain the science and reasoning behind the different workouts. While, I am not longer working out at Flash Fitness, I still use the tips Jeff gave me for weight training. And, I would be glad to go back to Flash Fitness to train more 🙂”

 

Addisorn

“Everyone talks about the workout and results.  But Ritah & Jeff are much more than just fitness trainers.  They have created atmosphere that nurtures incredible community full of amazing people.  They are great human beings.”

 

Brenda F

“Ritah & Jeff thank you for getting me truely fit for the first time in my life! I was nervous to come along for fear of being too unfit but soon I found myself not wanting to miss a session. Your genuine care for people, sense of fostering a great community of good hearted people and your ability to motivate all levels to what you know they can do makes a winning formula. So grateful to you both! Best gym not only in Bangkok but anywhere! Missing you a lot now I’m back in Australia but will come back to visit!!”

 

Tess P

“if you’re looking for a place to train that is wholesome, supportive and effective - go to Flash. Jeff and Ritah deliver top notch training, holistic, science-backed programming – and (mostly) good jokes. You won’t find people more committed to supporting your wellbeing and happiness, in and out of the gym. Forever grateful ♥️”

Cris

Flash Fitness changed the way I looked at working out!

Jeff and Rita are awesome, and giving only 5 stars, having experienced the care and commitment to the wellbeing of anyone that shows up at flash fitness is too little!

I can’t recommend them enough!”

 

Jill A.

“we have worked with Jeff and Ritah for many years and we have nothing but praise for their methodology and work ethic. They are still the best trainers we have ever come across along with being my favourite people in Bangkok, which is difficult to say when we used to call them the 'tortures'. We would highly recommend them to anyone looking to get healthy and fit.”

 

Vera S.

“Without Jeff and Ritah, I wouldn't be where I am now. I have tried to lose weight many times in my life. Now I've finally done it. I managed to lose over 10 kilos in Thailand in 6 months. And I was not motivated at all in the beginning!

Thanks to great and easy-to-implement nutrition tips and online training that they offer, I was also able to lose more than 10 kilos in my home country (with a much unhealthier diet and significantly more stress than in Thailand).

But the community there is what motivates you the most and ensures that you come back. Jeff and Ritah themselves have great personalities. Being able to joke around during training makes everything a great experience.

I remember when I sat on my bed in Thailand and rather reluctantly looked for a gym, because I knew something had to change. I had the hope that maybe it would finally work out and maybe I could also meet cool people. I didn't think it could really happen at the time. But luckily I was wrong. Thank you Jeff and Ritah ❤️”

C.J.

“Flash Fitness is best community in Bangkok that I’ve been extremely fortunate to be a part of. Jeff and Ritah’s care and support in my overall health, wellbeing and fitness have made such impacts on my life that a testimonial simply cannot explain. If you want a gym experience where you feel a strong sense of belonging and encouragement, look no further.

Their training has helped me gain 12kg in muscle and changed the way I think about fitness. Now onto my third year! Thank you both for everything you do!! 💪”

 

Erin E

“I have gone to a few of the big gyms in Bangkok and I'd highly recommend Flash Fitness. They helped a lot with my form and making sure you get the most out of each workout. Jeff and Ritah are really kind, attentive and it's always a fun class. They are very supportive and it's a comfortable and encouraging place to push yourself and see results.”

The space is small, which I love because it feels personal and like a community 🫶

“Update 2025:

Still going, still enjoying the flash community! Ritah and Jeff are amazing trainers and they push you to take care of your health and your body. It's one of those places where they will reach out to you if you haven't showed up and ask if you are okay! Just like in a school setting :) which is known to create a routine and (even if supervised) discipline! And routine and discipline will bring results.

Wrote in 2023:

Im not a gym going person at all, BUT, I have joined Flash about half a year ago and I really love coming here. The trainers -Ritah and Jeff-  are awesome and the community is really welcoming not intimidating at all. I would say all levels are welcome and you will see results even if that wasnt your main goal (mine was just to hang out with cool people while sweating and listening to some music...all this before bedtime 😂)...however if that is your objective you will definitely see progress of your health and fitness within a short time!

Bring some (sugar-free) cake if you do decide to join! 💪🏻”

I signed up for another season and I am excited to establish healthy relationship with myself and the rest of the gang here.“

 

Stephen

“I am more than happy to share my outstanding experience at Flash Fitness. From the moment I walked through the doors in 2019, I knew I had found my fitness haven. With Jeff's expertise and the warm hospitality provided by both Jeff and Ritah, this gym has exceeded all my expectations.

 First and foremost, Jeff's extensive knowledge and passion for fitness truly shine through in every class. Whether it's strength training or cardio Jeff's guidance ensures that each workout is effective, engaging, and tailored to individual needs. His expertise is unparalleled, and his ability to educate and motivate is truly inspiring.

What sets this gym apart is the remarkable sense of community fostered by Jeff and Ritah. They have created an environment where everyone feels welcome, regardless of their fitness level or experience. The gym's friendly atmosphere encourages camaraderie, and it's wonderful to witness the mutual support and encouragement among members. It truly feels like a fitness family!

 The class-based approach is fantastic, as it allows for variety and ensures that every workout is dynamic and engaging.  Would highly recommend Flash Fitness to anybody in Bangkok!”

“I got my Sixpack from Flash within about 2-3 months then I couldn't stop going there because it's not just about getting healthy but it's also about the good vibe Jaff and Rita provided.

Beside training I also got to know how to eat better and sometimes if I need kinda fast track to get in shape Jeff and Rita also guide me to achieve the goal.

I'm now leaving in the Netherlands and I miss going to Flash very much. Flash is one of the best experience I've ever had. Thank you very much. 😘”

Dr. Pat is a PhD cancer researcher and nutritionist who has been training with Flash for several years and now has her 71 year old father training with Jeff 1-on-1. This is what she has to say:

“A great gym with lovely, encouraging coaches, Flash Fitness gives you real results and good vibes (everyone there is warm and welcoming, unpretentious, and you feel like part of the Flash team). Workout routines are great for all levels at a really good price (best thing about it is there is no expiry date on a course, so you can work out at your own pace, but of course you need to come often to see huge changes). The workout varies every day ranging from functional training to strength and conditioning, with an added mix of cardio so there's something different for the addicted gym rat coming mon-sat. Love the place, great location, highly recommend it.”

  

Karen D.

“Flash fitness has a very personal touch, meeting your needs at whatever fitness level you are at, whether you are you are new to exercise or looking to challenge yourself more. Jeff and Ritah are always welcoming and encouraging. I’m so pleased I was introduced to flash fitness in 2019.”

 

Bluebell R.

“The best gym in the world. Jeff and Ritah don’t just coach you so that you’ll lose some fat but they also creat this amazing community for gym maniacs so that we can share the experience together. This is not a place that you’ll come just to lose few kilos. They have shape you behavior to be healthy person inside and out so that you’ll stay healthy forever. Thank you for the good work guys, cheers!”

 

K.C.

“As a gym novice, I used to be intimidated by most of gyms and classes. BUT Flash really blows that away for me! This place is fun, friendly and very professional.

Jeff and Kru Ritah are professional and highly experienced in what they do. The workout they provide is challenging, yet satisfying within the span of 30 mins. Also gained insightful fitness & nutrition knowledge from here that can & still be used for life. 10/10 recommend!”

Therese B. Has trained with Flash for more than 10 years. First, in our group classes, and since moving back to France, continues via the Flash Online Training program. This is what she says: “When I arrived in Bangkok in 2015, sleep deprivation, low energy and back pain were my common symptoms. A friend of mine recommended Flash. The first lessons were hard. By hard I mean I needed to hold on to the rail to go down the stairs but it’s worth the effort. The more you go, the better and fitter you feel. One of the things I love the most about Flash, beside Jeff, Ritah and the community, is that the workouts are short, between 20-30 minutes. You need just 2 sessions per week to stay fit!

I left Bangkok recently and fortunately they have online trainings. I have tried a lot of gym classes, in the US and France, but believe me, nothing is as comparable. Give it a try, you will not regret it!”

 

Robin H. Has trained with Flash Fitness for 10+ years…both as a private client and has done the group classes. This is what she has to say: “I love Flash! I can’t praise Flash, Jeff, and Ritah enough. Jeff’s energy and enthusiasm is contagious, and his knowledge of exercise and nutrition is extensive. When I was going to Flash classes I was in the best shape of my life. It doesn’t matter your age, if you go to Flash classes and follow some of his eating habit suggestions you will look and feel great!”

 

Ai

“My husband and I ve been coming to Ritah and Jeff private classes since 2019 when we are in Thailand. Flash fitness has the best promising result that we ve never experienced anywhere else. During class, we are encouraged to trust our body capacity. It has been great cheerful experience. Both of them are professional and resourceful. Group class with other peers were fun and great vibe, both local and expats. Recommend for those who wud like to see the overall fitness result.”

 

Lucy

“I’ve been coming to flash for about 4 years. I’m the fittest I’ve ever been, and I can’t imagine going anywhere else now. Jeff and Ritah are extremely knowledgable and supportive, and it’s a really warm community atmosphere. The workouts are varied and challenging…and done in 30 minutes :)”

 

Rosie

“This is the perfect gym for me. As a working mother of two young children, the sessions are quick and effective allowing time for me to focus on myself without feeling the mummy guilts. I’ve not only lost a few kgs but I feel so much fitter and stronger since joining Flash. It really is an incredible place!”

 

Stephen L

“Small, personalized classes means you get to work out with friends (or make new friends!) under the supervision of trainers who really know what they are doing. Every week, there are three short, sharp workouts designed to get that body moving, the fat disappearing, and muscles growing. It works. I'm 53 and I these workouts have been keeping me fit and strong for the last 10 years. If you really want to get fit, lose weight or prepare for a challenging event of some sort, you absolutely need to come to this place.”

 

Phil W.

“I lost over 10kgs at Flash Fitness. This is a really great small but friendly gym in the heart of silom close to BTS and MRT. I have trained here for 5 years and have never been fitter. Having left Bangkok I still train with flash through their online programme, am still feeling fit. Best thing about flash is the personal attention to your fitness goals. Jeff and Ritah take the time to know each person individually and work on training and diet for that individual.”

 

James

Kulvara (Start is her nickname) has been coming to Flash Fitness for most of the last 10 years. (She had a two year break in the middle when she lived in the UK) Here’s what she says:

“Best gym ever. Jeff n Ritah are the best!!! 

I worked out for 7-8 years and tried nearly all fitness clubs. I never got results. When I joined here, I didn’t expect results. In only 15-16 weeks, BOOM! 15% of my bodyfat was gone! I love it here, both the programs and the people. Highly recommended! 

 

Michele L is in her early 60s, worked and trained in the group classes. This is what she says: 

”Training with Ritah and Jeff has been one of the most improtant and favorite things about my years in Bangkok.

John H trained as a private client with Jeff and is in his early 70s. Here is what he says about training with Jeff: 

”Training with Jeff was a great experience…I think.Haha. the best part is when it’s over. 

But you could really feel the difference. I quickly became fitter and stronger and it helped restore movement in my joints and shoulders that I had lost from all the years I spent at a desk over the years.”

“I signed up for a one-month membership with Flash Fitness from Canada, and I started seeing results after just a few sessions. During my stay in Thailand, I also had the chance to visit the gym in person and meet Jeff and Ritah…both are incredibly attentive, motivating, and supportive coaches.

I am currently continuing my training online because the benefits have been so significant for me. As we age, muscle loss can lead to a general loss of tone and firmness, but thanks to their workouts, I feel stronger, more toned, and I have much more energy.

They also provided valuable nutrition guidance that made a real difference in my results and overall well-being. The training is very flexible and efficient, and it doesn’t require a lot of time, which makes it easy to stay consistent.

I am very grateful for their support and very happy to have met them. Thank you both so much!”
