Gymbox Opiniones 

Attended what gymbox described as an Ashtanga yoga class.

Ashtanga is a very precise form of yoga and altnough teachers often skip some poses in the sequence when time is short, the actual poses are always taught in a distinct way.

The teacher at Gymbox taught most poses incorrectly and did not mention or demonstrate the most basic elements of Ashtanga which are the use of ‘banda,’ (core) and the breathing technique (ujjayi). The opening sun salutations were demonstrated and taught incorrectly as were forward bends and some of the advanced finishing poses.

I really suspected this teacher was untrained and uncertified. The Gymbox receptionist was unable to confirm if they were checking teachers’ credentials.

I had a very disappointing experience with Gymbox, and I would encourage anyone considering joining to read the membership terms very carefully. They are greedy and do not care about their members. During my gym tour, I was told that I could cancel my membership if I left London. I relied on that information when I signed up. When I later had to leave the UK, Gymbox refused to honour what I had been told.

I have fibromyalgia and experienced a severe flare-up, which forced me to leave the UK for health reasons. As a result, I could no longer use the gym. I explained my circumstances, hoping for some understanding or flexibility, but Gymbox insisted on pursuing the remaining balance of my fixed-term contract.

The alleged debt was then passed to a debt collection agency. I formally disputed the debt and requested copies of the membership agreement, statements, and evidence supporting the amount claimed. My request was never addressed. Instead, I continued receiving debt collection emails threatening legal action, followed by settlement offers, without first providing the evidence I had requested.

In my opinion, Gymbox prioritised recovering money over treating a long-standing member fairly and with compassion. As someone with a disability who was forced to leave the country due to serious health issues, I felt there was no consideration for my wellbeing or my circumstances.

The entire experience has been incredibly stressful and has completely changed my opinion of the company. I would strongly advise anyone considering a long-term membership to think carefully before signing a contract, as life circumstances can change unexpectedly.
Another major disappointment was the red light therapy. One of the main reasons I joined Gymbox was to make use of the red light therapy, hoping it would help with my health condition and chronic pain. However, during almost six months of membership, I only managed to book one session because it was always fully booked.
To make matters worse, when I finally got in, the smell was absolutely awful and unbearable. The room had a strong, stale men's sweaty smell. The facility clearly lacks proper hygiene and regular cleaning. Please have someone check and freshen up the room throughout the day, as not all members have basic hygiene habits. It was a disgusting experience.

Based on my experience, I cannot recommend Gymbox and would advise potential members to look elsewhere.

I went for a single try out session and have since been receiving daily calls, texts and emails. I’ve complained so many times, they still won’t leave me alone. I’m going to have to change my number.

Stratford Gymbox has no air con. It hasn't had for weeks with very little comms updating us on the situation. But here's thing - they keep the front door open. When asked reception, they said the door is open for their comfort. I'm all for their health and safety but wouldn't a simple fan and portable air con machine placed in reception be a good solution for them so we can keep the door shut so the heat doesn't rise to the gym (which is upstairs from reception where it's paying customers hang out). Pretty dismissive - no update offered - no attempt of empathy.

When my minimum contract term ended, I stayed on a rolling membership expecting the flexibility that implies. Instead, within a short window, my monthly fee was hit with a 13% increase — introduced in two stages, with barely any warning in between.

I contacted Gymbox through their official contact form on 1st June to ask about the terms under Chapter 9.5 of the T&Cs. I received no confirmation, no reply, nothing. When I tried emailing their central service address directly, the message bounced back as undeliverable.
By July, the higher fee had already been taken from my account. Their policy only allows cancellation without penalty if requested before a set deadline — meaning if the company ignores your enquiry long enough, they simply run out the clock on your rights while still collecting the increase.

The gym facilities themselves are fine, but the way out-of-contract members are treated financially, and the complete lack of accessible customer service, made this a genuinely frustrating experience. Would think twice before staying on a rolling contract with them again.

terrible facilities and the classes are always full.

also trying to cancel your membership is the most difficult process. either upgrade the class booking number of people or don't have any classes at all.

they will charge you with a huge bill for wanting to cancel (even if you're under 25)

I am extremely frustrated and disappointed with my experience at Gymbox Ealing. I specifically chose this branch because it is convenient for my workplace, even though I had to travel from a different area to get there.
I booked two slots on their official website: a Free Gym Trial and a Free InBody Test & Consultation.
The issues started before I even arrived. I received a call from them while I was on my way to confirm my attendance. The staff member started asking intrusive questions about where I live, which made me feel highly uncomfortable. Out of nowhere, they then claimed I had to pay £25 for a day pass. I told them I had a confirmed free trial booking and suggested we speak when I arrived.
Due to a tube delay, I arrived 10 minutes late. I then had to wait at reception for another 15 minutes just to be seen. When they finally attended to me, they casually informed me that the trainer wasn't even there!
To make matters worse, the receptionist was incredibly rude and cheeky. She tried to shift the blame onto me, saying it was because I was late. This was a blatant lie to cover up their own system failure or their irresponsible trainer who simply failed to show up. It genuinely felt like they never intended to let me use the trial in the first place and were just looking for any excuse to brush me off and get rid of me.
The entire experience was absolutely humiliating. This was a massive waste of my time and energy. I will absolutely be warning all of my colleagues in the area to stay far away from Gymbox Ealing. I sincerely hope to find a much better, more professional gym in that area. Just waisted a day off. Avoid at all costs.

Facilities are ok, though at random times they host classes on the gym floor and private coaches prevent you from using the equipment.

Customer service was very responsive until i signed the contract. After that i discovered all the malicious clauses ans terms that are made to ensure steady revenue for gym-box while minimum flexibility for customers and maximum penalties. The staff at the gum give conflicting advice to the website and the online agents.

Without any warning, Gymbox increased my monthly fee from £65 to £82.50 — a 27% jump. I never received any email about it. When I questioned it, they admitted the email they claimed to have sent me had bounced and never arrived.

Their own terms say fee increases must follow inflation (CPI), which was around 2-3% at the time. They have never been able to explain how 27% is in line with inflation. After weeks of back and forth through multiple staff members all the way to a team leader, not one person could point to a single rule in their own terms that justified the increase.

When I asked for a refund of the overcharges, their solution was to offer me my old rate back, but only if I signed a new 12-month contract. So their answer to an error on their part was to demand more commitment from me.

I’ve had to raise a formal bank dispute, report them to Trading Standards, and submit a legal data request just to get anywhere. They closed my complaint without resolving it.

If you’re thinking of joining, don’t. Be aware that your fee could go up significantly with no warning, and getting any answer out of their customer service team is an exercise in frustration. Check your bank statements every month.

Poor hygiene… absolutely stinks of stale male urine as you walk in past the men’s changing room. Never and shampoo/conditioner in the women’s changing room. Really expensive gym for fairly grim surroundings

This place is an absolute scam, they woo you with a free membership and discount and make it absolutely impossible to quit by ignoring your calls and emails and then charging you hidden fees. Don’t fall for the scam!

Terrible membership terms that trap you into a long term contract with no escape if your circumstances change. I had to relocate which meant I could no longer access the gym but customer service was rude and unhelpful and refused to terminate my contract without a huge exit fee (which worked out more than if I just let the contract run its course). A shame because the gym itself was actually quite nice. Never using this gym again.

If I could give zero stars I would. Terrible company. Abysmal customer service. You can never speak to anyone. You’re promised call backs and get nothing. They admit they have internal issues with their direct debit system and they then refer me to debt collectors - it’s their issue! Awful awful awful

I booked a trial visit at Stratford Westfields gym Box as it states on the site that you can ‘book a trial visit or tour before becoming a member’

I was met by sales guru Samaaira , whose immediate approach with me appeared to be somewhat agitated or disgruntled.

Samaaira asked if I was here for trail day. I expressed that I was. Samaaira stated that she would provide a tour, only if I became a member first.

I expressed that I am interested in joining, but would need to see and use the facilities before signing up.

Samaaira expressed that Gym Box are being very strict and are now only doing trial days and tours if you sign up first. Samaaira then asked if I am a member of any other gyms. I expressed that I am a member of two gyms.

Samaaira then stated that I am not applicable to join as I would not be able to sign up to a third Gym.

I found this to be an odd, as I have never heard of this type of policy before. However I informed Samaaira about that I would cancel my other two memberships if I like this Gym as I would prefer to be a member of 1, with all the facilities I require in one place anyway.

Samira then again reiterated that Gym box are being extremely strict and are only allowing tours and trial dates to go ahead after you’ve signed up for a membership prior, and apologised stating that she could not help me any further.

I have not seen anything on the Gym box site confirming that this is accurate. Not only does this seem nonsensical, but Samaaira‘s delivery and approach was extremely dismissive and rude.

The gym itself is visually impressive and the staff on site were generally polite, but the overall culture felt very “Love Island” — image-focused, influencer-heavy, and extremely sales-driven. Everything feels built around appearance, upselling, and locking people into contracts rather than creating a genuinely supportive environment.

My experience with the membership side of the business completely overshadowed anything positive about the gym itself.

After losing my job, I attempted to cancel under their redundancy/unemployment clause. I provided official legal settlement documentation from my former employer referencing statutory redundancy entitlement and termination of employment. Despite this, Gymbox refused to accept the documentation because it was not in the exact format they wanted, even though my former employer does not issue standalone redundancy letters.

This led to an exhausting and repetitive back-and-forth where I repeatedly had to explain and highlight the same sections of the document over and over again, only to eventually be told I would still need to pay a substantial early termination fee.

To be fair, Natalia from member services remained polite and professional throughout, and I appreciate that she was following company policy. My issue is not with individual staff members, but with a process that felt inflexible, unnecessarily stressful, and completely lacking in reasonable discretion during an already difficult situation.

I left feeling far more like a contract than a customer.

Extremely disappointed by my experience with Gymbox Ealing and Gymbox Membership Accounts.

I recently had to cancel my membership due to serious spinal and neck issues and am currently undergoing spinal surgery. Despite explaining my medical circumstances multiple times, Gymbox continued to pursue a final monthly payment, even though I had not been using the gym for months because of my condition.

What shocked me most was the complete lack of empathy, compassion, or reasonable discretion shown throughout the process. At no stage did anyone meaningfully try to understand the situation, discuss a fair resolution, or even request medical evidence before escalating matters.

Instead, whilst I was still awaiting responses regarding my complaint and cancellation dispute, I received an email threatening referral to a debt collection agency. At a time when I should have been focusing on my health and surgery, I was instead dealing with unnecessary stress and pressure over a gym membership I physically could not use.

I ultimately paid the £94 simply to stop the stress, but I did so completely under protest and do not believe the handling of this situation was fair or reasonable.

The issue here is not just the money, it is the way Gymbox chooses to treat customers facing genuine medical difficulties. Policies are one thing, but basic compassion and common sense should also exist.

Having since looked online, I can also see multiple similar complaints from other members relating to cancellations, rigid contract enforcement, and poor customer care.

Sadly, after this experience, I will never join Gymbox again and cannot recommend them based on how this situation was handled.

Very disappointing experience at Gymbox Finsbury Park.
I had a valid membership running from 12 May 2025 until 12 May 2026, and I even showed my confirmation email at reception. Despite this, I was refused entry and told incorrectly that my membership ended on 1 May.

The receptionist was extremely rude, dismissive, and refused to provide their name or call a manager when requested. I felt unfairly and disrespectfully treated throughout the entire interaction. I also recorded the incident on video due to the seriousness of the situation.

As a loyal member for the past year, this level of customer service and professionalism is unacceptable. Very stressful and disappointing experience.

Shocking company.
Treats members like fodder. Find another company with integrity and give this place a wide birth.

I would advise anyone to avoid this company and see elsewhere.
I had my locker padlock removed and contents stolen. My complaint was dismissed as no cameras exist in the changing rooms.
I was also pursued by ARC debt collectors for the locker cancellation even though I had no contract for the locker and followed their instructions for cancellation.
BEWARE, the membership and customer support team follow the Gym Box policy to follow blindly the company savagery and avoid customer legitimate complaints and issues. Better to use via Hussle or pay as you go but avoid signing any contract by all means.

Gymbox Westfield White City has really gone downhill since the new management. Front desk staff are often disinterested, unhelpful, and sometimes patronizing. Facilities are poor—dirty bathrooms, cold showers, no towels or body wash. Equipment is damaged, classes are overcrowded and unsafe at times, and prices keep rising without informing members. Management and customer service don’t respond to complaints.

Used to be a great gym, but now I wouldn’t recommend it—definitely not worth the price.
