Because of my job I travel everywhere in England and I’ve been to so many gyms in London and outside of London, this one is the best. I love this gym!

Overrated an understatement. Very unwelcoming, cash only??? All plates need replacing, extremely tired looking. Weights all over the floor, no mirror space. Havent used this gym in 12 years and its no money or even maintenance done on the place in that time.

Equipment not so new but it's all about training here no frills. Always have the regulars here and a great dedicated atmosphere which really helps for serious training. Great boxing equipment and cage area too which gives it a differential advantage against other modern gyms.

Great gym great atmosphere! First time here and felt welcomed by the friendly staff ... the sparing area I used was fantastic and they also have a cage which was conviniant. Great equipment and very tidy! High sealing and well spaced. The kitchen area was spotless and the staff were ladies always a plus imo. The fans were not on as we were training so it was slightly hot whilst training but I'm sure if we mentioned to the staff then they would of a activated the fans. Other than that definitely a spot to train and release some stress.. the monster theme they have is quite impressive and works well . Thanks guys

I come back to the uk to visit my parents and can’t wait to get to monster gym. Paul Rees the boxing coach is an absolute diamond and I learnt more from him in one session than I did in 4 years at boxing gyms where I train. The gym itself is probably the best gym I have ever visited and the atmosphere is totally non threatening to anyone, a total lack of arrogance or snobiness so anyone can train there comfortably. I can’t give this gym enough praise and I hope they continue doing the fantastic job they do

Has more then you would ever need a truly Fantastic Gym! Steve is a proper gentleman. Ps...sorry about the bin joke 😉 Love and respect 👍🏻💙💙💙💙❤❤❤❤

It’s a shame that I can only train here when on business travel in London. Amazing gym!

You can't go wrong working out at Monster 💪🏿

Best gym with the best owners and management ..bar none.

I go to Monster Gym for personal training. For extra Brazilian Jiu Jitsu lessons as well as strength and conditioning. The Gym is well equipped but it's all looking a bit tired. It could do with brightening up and other maintenance. It's a good Gym if your serious about getting fit

Not a very welcoming place cash only no cashpoint around dumbbells are awful falling apart cables have pins from scrap metal look like they where found in a skip ropes weel surprised they actually are still usable really felt uncomfortable here been twice now not going back even guys that have been going there for years one said to me mate I don't really bother doing g arms I can't be bothered sorting threw that all the time nobody shares machines all horrible negatives really not worth the money I bought a day pass and went in for 1 hour on my break and said to the fella after work ill pop back in he said you have to pay for a nother pass it's a session pass not a day so many negatives

Best gym in the UNIVERSE. Still the same..Fantastic!! Still great as ever! Fantastic energy.! It's still great as ever!

Does not say anything about cash only wat gym does cash only

Using this gym while working nearby. Fantastic gym! Amazing quality equipment and a huge range to choose from! Kitchen has amazing quality healthy food. Wish this was my local gym!

Monster Gym is quite a large gym it's also dark as there isnt much lighting. The ground floor is set up with machines/equipment and free weights. These are all a bit haggered and broken in parts. The first floor is split into 2 sections. One section offers mostly bikes. The other section offers punch bags, a boxing ring, mats and another sparring area. Could do with a bit of a refurbishment as the roof leaks and it can be drafty. The mats could be kept better as can be dirty and got some rips.

Best Gym Around, Can't match it, the Range of Hammer Strength machines to Exercise every muscle group in different ways hitting every section of that muscle. And there are plenty of machines for every muscle group, so if it's busy you can still train the muscle you intended to. Proper Body Building Gym.👌🏽💪🏽

One of the best bodybuilding gyms in UK without doubt. Full of equipment!! Has a true hardcore atmosphere! You will never get bored training here

Great staff who are friendly and professional, user friendly environment, aka, something for everyone from, cardio machines to semi pro bodybuilding heavy weights. UK's only hammer gym.

Extensive range of equipment. Reasonably priced. Friendly staff Easy access, great location, plenty of free parking. Would highly recommend.

Amazing gym. I spent the first 4 years of my training at Monster Gym, and the experience was fantastic. I'm now a personal trainer based in Harlow, with a thriving client base, and it roots all the way back to Monster Gym. Looking forward to re-visiting one day soon!

Great Gym Equipment great and lots of unique machines. Proper hard core gym. Great for men and women Great positive vibe All staff welcoming.
