Gymbox Avis 

They’re overselling, misleading about the crowd.

You can’t cancel your membership easily, they just made intentionally difficult the whole process.

Long story short worst gym experience when you consider how much they charge.

Deceptive and Overcrowded
Absolutely terrible experience. The sales staff completely misled me about class availability and gym access. They painted a picture of an amazing facility, but in reality, the gym is so overcrowded you can’t even use the equipment. Classes are impossible to book despite their 'over 20 classes a day' claim. Customer service? Non-existent. Avoid this place at all costs.

Basically, the staff are great - both teachers and support staff and Gymbox offers some excellent classes. Notes are that the weights area is crowded after work; I was really hoping to use the sauna but for me, it's too much dry heat and needs a bit of humidity added, and some classes on weekend afternoons would be great.

Its a very nice gym and the people are very friendly love the classes

The best classes with the best people.

Great classes and supportive staff!

I love the vibe in the gym. The gym actually is not too bad. They could fix the equipment much quicker as I’ve been going for a month to Stratford Westfield GYMBOX. I can see that some equipment is broken and it’s not been fixed for like two weeks, it’s a bit shame as I’ve heard GYMBOX it’s one of the best gyms in capital other than that, the stuff is super helpful toilet could be cleaned more often as well

I’ve just started to go to the gym and ever since going to the gym box I’ve loved it. The staff, trainers and teachers are incredible and so helpful as well as friendly. The machines are top notch and just over all the facilities are amazing

Won't remove me from their database despite requesting in person and in writing several times.

This is a violation of GDPR. I want to be removed from your lists.

The personal trainers at Old Street made me scared to come to the gym again.

I experienced dizziness at the gym so went to reception and was told to sit at a table on my own, with nobody checking up on me.

I left the gym still feeling dizzy because it was better than sitting on a table on my own out of sight.

Having tried to cancel my contract after this event. It was my second time visiting - I attribute passing out to the lights, nightclub-level volume of the music, and over crowdedness.

I was told verbally and trusted the staff member that there's a 14 day cancellation guarantee, but no mention of the fact that if you visit a second time, you can't exercise this cancellation.

So upon trying to cancel, they're utterly refusing to cancel my membership despite the environment, my experience with dizziness, and failure of duty of care shown by staff.

Now after trying to cancel my contract 7 days in, they've locked me in to another ~360 days point blank refusing that they've done anything wrong, trusting their employee's account over mine.

Requested to speak to a manger or a phone call to discuss the issue but have point blank been ignored on that request.

Avoid Gymbox at all costs.

Good facilities! Varied classes, clean showers, welcoming environment!!

Vinyasa and Hatha Yoga classes with Fiona at
GYMBOX bank are amazing!!!

I’ve been training with Jimmy Bell at Gymbox for the past few weeks and I can confidently say he is one of the best personal trainers out there. From day one, Jimmy took the time to understand my fitness goals, assess my current abilities, and create a personalised workout plan that pushed me beyond my comfort zone while ensuring I stayed motivated and injury-free.

Jimmy’s expertise is evident in the variety of exercises he incorporates into each session, always keeping things fresh, challenging, and fun. He has a knack for breaking down complex movements and explaining proper form in a way that’s easy to understand, which has made a huge difference in my progress. His attention to detail is impeccable—whether it’s adjusting my form or tweaking my routine to keep me progressing, I always feel like I’m in safe hands.

What truly sets Jimmy apart is his genuine passion for helping his clients succeed. He’s not just focused on short-term results; he’s committed to building sustainable, long-lasting habits. He’s also incredibly approachable and supportive, making the gym feel like a positive and energising environment. Even on days when I don’t feel 100%, Jimmy’s encouragement keeps me pushing through.

If you’re looking for a personal trainer who is knowledgeable, motivational, and genuinely invested in your fitness journey, Jimmy Bell is the person you need. I’ve seen fantastic results, and I’m excited to continue working with him to achieve even more. Highly recommend!

I had a very disappointing experience with Gymbox. When I initially signed up, I was told about a promotional rate and straightforward membership terms. However, it quickly became clear that they didn’t fully disclose important details, such as upgrade clauses and an unexpected cancellation fee. It feels like I was misled from the start, signing up under false pretences.

When I attempted to clarify these hidden fees, customer service failed to respond. There is no telephone number to contact to speak to someone

I expected a trustworthy and transparent gym, but instead, I’ve ended up with frustration and unexpected charges. I would not recommend this gym to anyone looking for a fair and honest membership experience.

Avoid this gym at all costs they will steal your money!

Really nice gym. Great equipment, large changing rooms and nice staff.

I really like how many classes there are available and the staff is the nicest! but I hate the gym lightining, its so chaotic and disturbing. Also, the place smells really bad and muffled and the water fountains are dirty.

The only positive thing is how friendly and helpful the staff are. Management and strategy of this gym is appalling. Everybody pays a different (albeit extortionate) fee and the facilities are simply not worth the price. I tried their classes and found them underwhelming. You should have a separate membership that excludes the classes. Showers are often out of conditioner. Sauna is nice but floor gets so hot it burns your feet. Regular water leaks in the lifting area. Blinding lights at eye level that make the lifting area very dangerous (we try to cover them with towels). Music is so loud you can’t hear the coaching. Very poor gym experience. I found a much better one for half the price. Very gimmicky and disingenuous gym, just looking to get you to sign up long term with 0 regard for the customer really.

The whole review is about a staff member; Natalia who was extremely helpful and kind enough to solve my issues with Gymbox.
Thank you very much you should be an asset for Gymbox! (And I hope they give you a pay rise!)

Great spin classes , funky interior, clean shower and changing room, wide range of classes and friendly and helpful reception staff.

Too congested everyday, not so clean
