Real people. Real results.

Had an amazing 36 sessions with Hafidz. I was very new to this, and his instructions and guidance helped me become much better at it. The results are gradual and apparent too. Thank you, Hafidz! ⚡

I've been training with Shaik for over 2 years and he helped me build a solid foundation in strength training. He's knowledgeable, encouraging, and always pushes me to challenge myself. I've definitely become stronger and more confident in the gym. Highly recommend!

I've been training at Flex Fitness regularly and it's honestly one of the best decisions I've made for my health. My trainer Shaik is professional, attentive, and really knows how to tailor sessions to each person's level and goals. I trust this place so much that I've brought my mum and several friends here too — every single one of them came away impressed and gave great feedback. Whether you're just starting out or looking to level up, this is the place to go. Highly recommend! 💪

All of the best bits of old Flex Fitness in a new 'Playground' with more equipment to try and improve with. Personally have never seen calibrated and perfectly matched weights in a public gym but can try now. Shaik is very flexible with training styles and will bring in individual movements to suit your style and goals.

Super clean super spacious with superb coaches who got me in the best shape of my life !!!

Had a great fitness journey with Shaik; got us to where we wanted to be just ahead of our wedding. Understands where you are each week and tailors accordingly. Really friendly chap.

Went to this gym and trained with Personal trainer Samuel Chou for 10+ sessions. Lost a total of 5.5kg. Can see results visibly. Trainer was good as he kept me accountable on my diet. And he taught me how to do exercises correctly that will not injure myself. Trainer was also friendly and highly motivated. Highly recommended for anyone who wants to lose weight or just keep fit.

Great place for training with my PT Shaik. He is knowledgeable and friendly.

Went for a trial PT session at Flex with trainer Samuel this morning. Friendly guy who looks at my strengths & limitations, and adjusted the session.

They have a nice facility with all the necessary gym equipment. The gym is good for strength training and cardio training, and on top they have HYROX training classes too! They have many trainers if you want to get PT sessions.

Just had my first group lesson at this gym and it was awesome! The gym has a great vibe, and everyone was really friendly. I'm excited to join more group lessons in the future. Highly recommend!

Flex Fitness isn't just a gym—it's like your second home, but with more sweat and fewer couches! The coaches are absolute legends who know their stuff and make every workout feel like a win (even when your legs are begging for mercy). The community? Unbeatable. Everyone's cheering you on, laughing through the pain, and celebrating every milestone with you. If you're looking for expert coaching, good vibes, and a squad that actually makes working out fun, Flex Fitness is the place to be!

A wonderful gym at River Valley with a good range of equipment! I always have a good time training here with friends and coaches as we prepare for our upcoming races.

Trained at Flex Fitness in the last trimester of my pregnancy. At this point I had bad back pain and had to stop my normal high impact classes and running. Shaik tailored the sessions for prenatal strength and made it fun by targeting exercises which are functional and relatable to holding my baby in the first months when I won't be able to train postpartum. He also taught me about diastasis recti and corrected my form and advised on some exercises which could unknowingly damage me. I bought a 10 session pack which I fully utilised and plan to return postpartum before going back into more high impact group classes.

What I think of Hafidz as my Personal Trainer. These 5 words: Efficient, patient, helpful, humorous and inspiring.

Started my weight loss journey at Flex Fitness in Jan 2024 as I wanted to look good for my wedding in Sept 2024. Started at 68kg and I am 59.5kg as of this morning. I'm very happy with my result. Feeling more confident and want to dress up more! Shaik gave clear guidance, provided the right amount of accountability, and improved my form and knowledge on training. Thank you for making this happen, Shaik!

It has been a transformative 6 weeks to build strength before my wedding reception! I managed to also lose 4.5kg during this period. Shaik has been a very positive influence and keeps me motivated to bring out the best in myself. If you are looking for results, this is it!

I've joined Flex Fitness for 6 months. I'm getting fitter under the guidance of my trainer Hafidz. The training environment is good, not so crowded and noisy. Would definitely recommend to my friends to join if they are interested.

I've been training with Flex, and I'm incredibly impressed. The trainer is knowledgeable, friendly, and really motivates me to push myself. The gym is a safe environment and I felt no judgement training there. The facilities are clean and well-maintained, and I appreciate the variety of equipment available. I've already seen improvements in my strength and overall fitness level. Highly recommend!

For residents living in the River Valley area, this newly opened personal training gym is conveniently located and just a stone's throw away from Mohammad Sultan Road with ample parking around the vicinity. The gym equipment is new and well maintained, with a cosy pantry and a small shower facility. I was blessed to be trained by Shaik, the master trainer. Shaik is an experienced and patient trainer who is ever willing to share his knowledge on the science behind muscle building, weight loss and posture. He shows genuine concern for his trainees' physical wellbeing and safety and is mindful of their limitations so that injuries can be avoided. As a person, he is responsible, chatty and friendly; it is definitely a joyful and pleasant experience training with him.

I was looking for a gym in SG close to my house in River Valley. I found Flex and I feel so much better now. Shaik trained me during the last two years and I got amazing results. The gym is renovated and all the machinery is new, good for pump and cardio training.

Shaik (Flex Fitness owner) has been my fitness coach for 3+ years. He has helped me regain strength after a sustained neck pain and chronic condition. He has a great understanding of individual health conditions and needs, and is able to develop tailor-made training schedules based on unique situations and continually adjust. His work ethic and focus are equally exceptional. It has been great having him as my trainer and health coach.

The perfect gym to kick off one's fitness journey! Shaik is one of the most dynamic trainers I've had the pleasure of working with. His attention to detail and ability to inspire is impeccable. The gym itself is well designed with plenty of space and equipment. Definitely would recommend this establishment to family and friends!!

Amazing facilities, super friendly coaches, great workouts. Highly recommend :)

Had a great tailored workout, friendly folk and adorable mascot. 11/10 recommended!

Love this place! Shaik is very dedicated and determined to help you succeed. The gym is extremely well laid out, clean and has a private feel to it. If you are looking to get fit, learn about nutrition and get stronger, this is the best place to do it, and it's also conveniently located. Highly recommended!

I've been training with Shaik for the last 2 years, since he opened Flex last year. Shaik is not only a great personal trainer who takes on your personal goals and situations, but has created a gym which has a great atmosphere and all the equipment needed to get the job done. I would definitely recommend Shaik (or any of the trainers at the gym) if you are looking for a great and personable PT.

I've been training with Shaik for over 2 years and couldn't recommend him more. On top of that, his new space has an excellent layout and equipment. He's designed it in a way to allow for personal training sessions that don't feel too cramped, and he keeps it in great condition. Highly recommend anyone to try out some sessions… you won't regret it!

Have been training with Shaik for over a year now and would highly recommend Shaik and Flex Fitness. The gym is spacious and well equipped. Conveniently located and walking distance to MRT and Robertson Quay / River Valley. Shaik is a personable trainer who takes care to tailor a programme to suit his clients' needs.

I have been training under Shaik (the owner) for a good 2 years or so, even prior to him starting Flex Fitness and making a name for himself. Being scrawny and lightly built at the beginning of our training, Shaik guided and tailored my sessions to help shape my body in the right places. My physique has gained much improvement and is more balanced and healthy ever since. Shaik also possesses an approachable personality and does his best to accommodate my schedule. Truly a hard worker and thoughtful trainer.

Did a course with Hafidz and am really satisfied with the outcome! As someone who did not exercise much, Hafidz helped me to become fitter through exercises that suited my initial non-existent fitness level. It gave me confidence to pursue more fitness activities and continue to stay active. The workouts that Hafidz planned were quite simple yet effective, so there was minimal burnout after each session. I'd highly recommend this to anyone who's working to get fitter!

Loved the experience here, the trainers are extremely friendly and knowledgeable about fitness. Almost reached my 6-pack.

Absolutely love the space here, good environment and good equipment. Would recommend to anyone living around the area to give it a shot!

Great new gym. Very pleasant and friendly atmosphere. On my third week training and enjoying it a lot. If you are looking for help in reaching your fitness goals, you need to check this place out.

Been training with Shaik for three months after a shoulder SLAP tear. Delightful to see the progress in restoring fitness! In the meantime, surprised to have a 5kg weight loss following a well-balanced training and diet plan. Would strongly recommend the place for anyone, be it a novice or a gym veteran.

I have been training with Shaik for a couple of years and I enjoy his training sessions a lot! His training has been consistent and effective in helping me achieve my goals. He is also knowledgeable in his work and I have learned a lot from him. Would definitely recommend him if you are looking for a good trainer.

First session and really love the trainer. We did super sets for upper body today and I totally felt the strain in my muscles. Haven't done high reps in a long time but it was a lovely workout with Shaik. Congrats on the opening of the new gym!

The personal trainers at Flex Fitness are highly experienced and results-focused. Highly recommended for those looking to improve their fitness and lifestyle!

Great training with Shaik over the last couple of years. Seen some fantastic results and feeling stronger and fitter than ever. Thanks for your dedication and support.

All gyms have the same gravity, but no gym has Shaik (the owner). His personality and personal attention to your growth are second to none. He is always positive energy, always on time, and always flexible. Highly recommended you try out Flex!

Been training with Shaik since 2020! He's the trainer I trust with my prenatal workout sessions. 👍

Shaik is the best! He's been coaching me from 6 months postpartum until now, over a year.

Love Flex Fitness! My trainer is amazing and the gym is well equipped and really nice. I'm happy I chose this gym.

Fantastic new gym in the heart of River Valley. Great facilities, and friendly ownership! Shaik, the owner and trainer, has been an excellent coach, tailoring his approach to each individual client and their goals. His focus on form has helped me accelerate my work in the gym and hit my goals. Highly recommend to anyone looking for a PT in the area!

The cleanliness and aroma (lots of air fresheners) of the gym is amazing! Music is good and keeps me in a good mood and pumps me up for my workout. 💪 The trainer here is top notch 👌 Very motivating and does his best to get me in the best shape.

The space here is amazing and the trainers are extremely motivating, friendly and knowledgeable. 💪

Very happy with my trainer. We have been focusing on my form and strength and I can see improvements already in my muscle tone and posture.

Great new modern gym with lots of space, nice trainers who are definitely making a difference to my health and lifestyle. Highly recommend!
