So i'm a bit of a gym rat / fitness freak and i've been going to this gym since I moved to the area…read moreabout a year ago. It's in a great area and the best thing is that it's open 24 hours a day, which is perfect for me. Over the last few years, due to the recession, we have seen a lot of these cheap gym chains sprouting up and I usually go with the saying 'you get what you pay for'. Now where that's usually proved me right for the most part, it's completely untrue with this gym chain. Monthly rates are dirt cheap, usually around £20 and the gym has everything you could want and need in a gym - state of the art equipment, full range of free weights, stretching areas, changing rooms, classes and PT sessions. Notice I said gym and not HEALTH CLUB. When I go to the gym I like to TRAIN not swim, jacuzzi, play tennis, steam room, spa or play tennis. If that's what you want then this place is not for you, as it hasn't got any of them and you want somewhere like VIRGIN ACTIVE or DAVID LLOYD and the price that comes with it (upwards of £65 per month plus joining fee). When I joined this gym I was shocked at how cheap it was a month as I would have gladly paid double every month as that's what I was expecting to pay at least. It's clean, nicely decorated and has everything you would need and more in a gym. A few recommendations - - Take full advantage of the 24 hour services. I would say to not train after work 6-10pm on weekdays as you will not be able to do what you need to do in less than 2 hours so you may as well not have gone. I go before work during the week and sometimes at weekends and have no problem using the equipment I need. - They don't have a wide range of classes so take a look at what they have on the website and see if they do things you like if thats a factor for you. - Don't get PT sessions here. I've trained athletes and know bad trainers when I see them. Apart from a few, most of the trainers here recycle their sessions and don't make sure their clients are doing the exercises correctly. I think they care more about their money than helping them. Or if you do want sessions here send me a message and i'll recommend the good ones and I promise I don't know any of them personally to just be giving them your business! Apart from those minor points if you live local and are looking for a gym I thoroughly recommend this place!

Good gym for 20 quid a month. It's got all the cardio that you'll need, and if you're an off-hours…read moregym rat, the ideal place for you. Always has been clean for me, and the other patrons are a nice cross-section (read: not full of gym rats). PT professionals I have not seen to be amazing for the price - they seem more just like the contractors who didn't have a job elsewhere - and they cost 50 to 80 an hour typically. Better to head to Pure Fitness or to another big London PT house for that price (and maybe get medical insurance to cover it). The nautilus machines and free weights are plentiful during non-peak hours, though can get a bit crowded with the afterwork crowd. Either way, the gym is great value for money if you're within walking distance.

Heartcore is definitely an understatement. It is the most intense workout I have ever had. But,…read moreafter one class, I was hooked. It is situated right about the Hampstead tube station which wouldn't seem to be the best place for a Pilate studio; it is absolutely beautiful -- large arched windows, exposed brick and 8 reformers. I've had two instructors and both were fantastic -- Shaun will kick you in the arse and your body will cry for days afterward. Despite the soreness, you will see results pretty soon after. It's a bit pricey -- if you sign up on their website you receive a free class.

Worst customer service ever. They sell you packages to be used within a timeframe which are…read moreimpossible to use as their classes are fully booked or overbooked. Their response is that you can use another studio. The problem is the same in the other studios and they refuse to extend the validity of your package despite it being the lack of spaces in their classes which stops you from using it. Appalling and plain theft.

I haven't tried the services of Matt Roberts staff themselves, so I can't comment on that aspect,…read morebut I have been at this location to try the Yogasphere yoga classes (taught by Mandy Jhamat every Saturday - if you are interested, I wrote a separate review for them on their Yelp page - they rule). The studio has a really pleasant vibe. Especially ladies will understand the importance of a good quality bathroom so we can put ourselves together after a gym session. This one has it all: nice warm showers, complimentary good quality towels, well lit mirrors, hair straighteners, and a good range of Percy & Reed products for your hair in case you need a quick fix. All the areas of the studio were also spotless clean, which I find very important. Given the lovely Hampstead location which just invites you for a nice walk outside afterwards especially now that it's getting warmer, this is a lovely place to train, or to come for a relaxing but strengthening weekend yoga session.
