The Best Fitness Classes in London

Deciding on which gyms and fitness classes to go to in London is a pretty weighty task, especially if you’ve never actually been to any before. We’ve tried out a fair few over the years, with mixed results. That’s why we’ve picked our favourite of the bunch. Think of it as our treat to you. Don’t worry about getting us anything either… maybe just some Maltesers or a protein shake.

Oh, and let us know if we’ve missed anything.

The Foundry

What is it: A studio designed for raw, focused and tough training sessions

Where is it: Old Street, Vauxhall and Bank

Why would you go: If you’re looking for the kind of class that’ll push you to your limits without the need for flashy lighting, in-house DJs or gimmicks, The Foundry is the place to be. Although there are a range of classes covering everything from city strongman to more conventional high intensity workouts, the underlying theme here is training hard and training properly. They have massive tyres, enormous sandbags, prowlers, kettlebells, and pretty much anything else that’s going to make you train to your max, and all under the guidance of some of London’s most knowledgeable (and friendly) trainers.

Cost: A single drop-in class will set you back £20, with a ten session pack coming in at £179. You can also pay for unlimited sessions for £220 a month across both sites (cheaper with an annual contract).



What is it: The newish hardman/hardwoman on the block, featuring a range of strength, conditioning and cardio workouts.

Where is it: Victoria, Old Street, Oxford Street and Vauxhall

Why would you go: We love a really tough class, and they don’t get much tougher than some of the sessions over at Manor. The focus here is pushing hard and whether that’s boxing, lifting heavy or building endurance, you won’t get away with relaxing at the back. Their flagship location is over at Victoria where you can find The Yard – a massive two story car park that forms the home of one of the hardest classes we’ve tried for quite some time.

Cost: A single class will set you back £20, ten of them will cost you £170 and a monthly unlimited membership will set you back £145 for a single location and £180 for access to all of them.


Victus Soul

What is it: A cool studio offering HIIT workouts containing either treadmill work or boxing

Where is it: Aldgate

Why would you go: The cardio/weights class format is hardly a new thing, but it’s a format that seems to work extremely well. The system means you can pack in all of your strength, conditioning and cardio work into one killer session whilst switching between exercises types help to make it seem a hell of a lot more bearable. The fact it’s in a super swanky looking studio with state of the art equipment doesn’t hurt either.

Cost: A single class will set you back £20, ten of them will cost you £180 and a monthly unlimited membership will set you back £250.



What is it: Spin and HIIT classes at impressively kitted out locations across London

Where is it: Richmond, Moorgate, Blackfriars and Rathbone Square

Why would you go: The main focus of Digme is their selection of spin classes catering for all levels of fitness and training. With some of the more technical ones you also have interactive screens on the wall where an avatar of you can be seen cycling around various landscapes. Not into spin? Then head over to their Matrix sessions for a mix of SkillMills, Kettlebells, TRX and bodyweight exercises.

Cost: A single class will set you back £20, ten of them will cost you £169 and monthly memberships start at £125 a month for 8 classes.


Core Collective

What is it: Beautiful studios offering yoga, HIIT, Rowing, Spin and TRX, amongst other things.

Where is it: Kensington and Knightsbridge

Why would you go: If you’re looking for a ridiculously cool and beautifully designed studio that offers a hell of a lot of different classes, then Core Collective may be worth a look. Great trainers, well designed sessions, a great selection of equipment and a nice atmosphere to do it.

Cost: A single class will set you back £22, ten of them will cost you £180 and a monthly memberships start at £145 a month for 12 classes.



© In The Right Light

What is it: Relaxed and welcoming yoga studio with a massive selection of classes and a cafe.

Where is it: Peckham

Why would you go: We’re not the best at yoga over at The Allrounder, so when we head to a studio we want it to be somewhere we can have fun whilst desperately trying to learn. LEVELSIX is that kind of place. A friendly team, a impressively spacious studios, a really nice cafe menu and a selection of additional sessions including children’s yoga and a sauerkraut workshop.

Cost: A single class will set you back £14, ten of them will cost you £110 and a monthly memberships start at £88 (with a direct debit).


The Fitting Rooms

What is it: Small group training in a dedicated fitness space

Where is it: London bridge

Why would you go: If you’re looking for PT sessions without the pressure of a busy commercial gym, this is the place to go. With sessions tailored towards different fitness levels, from beginner to really focussed muscle-building classes, it’s one of the best choices you can make for a dedicated training plan. The small group training style puts you in with people at the same level as you, so you get almost the same attention to form and development you’d get in a dedicated PT session. The gym is also only open to people undergoing training, so you never have to worry about it being busy. Ruddy nice team there as well.

Cost: A single shared PT session (up to four people) will set you back £40, with a ten session pack coming in at £325. Private personal training is also available.


The Engine Room

What is it: A dedicated rowing studio with a shedload of workout data

Where is it: Great Portland Street

Why would you go: Rowing workouts are becoming a bit of a thing these days, so perhaps it’s no surprise that a studio cropped up with them at it’s core. The Engine Room is basically a Barry’s Bootcamp style workout space where the treadmills are removed to make way for state of the art rowing machines. It looks super cool, the workout data on screen is a thing of beauty and they even have neon disco lights to make sure you’re enjoying yourself against the background of expertly picked playlists.

Cost: A single class will cost you £19 (£14 for a 35-minute express class), 10 classes will set you back £170 and £195 will get you unlimited classes per month.



What is it: A club style studio predominantly focused on boxing

Where is it: Chelsea and Liverpool Street

Why would you go: If it’s a loud music, neon lights, lots of jumping and loads of sweating you want, then look no further. Alternating between punch bag combinations and floor exercises for 45 minutes will make sure you burn those calories without getting bored.

Cost: A single drop-in class will set you back £20, with a ridiculous number of bulk options available ranging from a 5 class pack (£95) to a 30 class pack for £360.


Sweat by BXR

What is it: A range rather nice HIIT classes in a super cool location

Where is it: Marleybone

Why would you go: As studios go, Sweat by BXR is one of the nicest looking in London. Which is what you’d probably expect from a brand working with Anthony Joshua. The classes range from strength and conditioning to the increasingly popular VersaClimber sessions, which is probably one of the toughest classes you’re ever likely to try. The major plus for Sweat by BXR is the focus on performance improving, instead of just trying to make you feel sick.

Cost: A single drop-in class for a non-BXR gym member will set you back £30 (£20 at lunch), with a twelve session pack coming in at £240. You can also pay for unlimited sessions for £300 a month. Check the website for introductory offers.



What is it: Fast-paced, high intensity, fun and ridiculously tough classes with loads of variety

Where is it: London Bridge, Fulham

Why would you go: We’ll level with you here, UN1T classes are a going to hurt. 45-minutes of relentless circuits with very little rest. Prowlers, shoulder presses, rowing, SkiErgs, Assault bikes, burpees – none of it screams “easy”. Somehow it seems to go quickly though, perhaps due to the sheer energy from the trainers. If it’s a full body workout you want with a load of cardio, you’ll struggle to find better.

Cost: A single drop-in class will set you back £20, with a ten session pack coming in at £180. You can also pay for unlimited sessions for £210 a month. The currently have a 14-day introductory pass for £39, which is ridiculous value for money.


Project Fit

What is it: A HIIT studio that combine floor and weight exercises and treadmill work

Where is it: Bank

Why would you go: The combination of intense cardio with strength and conditioning work makes for an amazing total workout. Not only will you burn loads of calories but you’ll also be working muscles all over the body. The mixture of running and floor work means that you move around so much, you tend to forget how much work you’re actually doing.

Cost: A single drop-in class for Project Fit will set you back £20, with credits for multiple sessions making it cheaper. You can also pay for unlimited sessions for £75 a week (cheaper if you pay for bulk deals) or take them up on a pretty sweet 50% off trial week.


Evolve 353

What is it: A beautiful little studio covering small group classes and individual personal training

Where is it: Fulham

Why would you go: By the end of the session we were covered in sweat, as usual, but it wasn’t because we’d just been made to do burpees for 45-minutes. We’d carried out a pretty exhaustive full-body workout, and been corrected on form a fair few times (yeah okay, we hate that… but we know it’s for our own good). Read our full review here.

Cost: Memberships start from £169 for unlimited sessions. There’s also a 30-day free trial going on at the moment, which sounds pretty good to us.



What is it: A state-of-the-art indoor cycling arena named Rider, and a Zen inspired, mind-body studio that focuses on lengthening, toning and strengthening.

Where is it: Crouch End. They’re also opening one in Borough soon

Why would you go: A well-executed transition from treadmill to gym floor to spin bike to yoga mat… by which point we were practically crawling into the hyper-cooled Zen room, sweat steaming off our backs. We finished our visit propped up at the in-house juice bar, which serves up an array of smoothies & shakes to weary tribespeople in need of refreshment.

Cost: Class packages range from a pay-per-class rate at £16 to an unlimited pass costing £155 a month.


British Military Fitness

What is it: A park based HIIT and running workout

Where is it: All over the city

Why would you go: A perfect all-round training for people who want to get fitter and healthier. It ticks a lot of boxes, managing to pack in strength, cardio, mobility and speed all into one carefully planned session. Being outdoors is a massive bonus as well, not to mention the social aspect of the whole thing (everyone is friendly, they do social events, that sort of thing).

Cost: £40 per month for one class a week or £54 for unlimited classes (becomes cheaper with longer contracts). You can also pay per session, with 10 coming in at £120.


Another Space

What is it: A swanky two-floor studio covering Yoga, Spin and HIIT

Where is it: Covent Garden, Bank

Why would you go: A boutique sister club to the ever-growing Third Space brand, Another_Space’s Seven Dials site is perfectly situated to serve the fitness needs of Midtown’s predominantly media & creative types. Mixing strength exercises with high-energy punchbag work. It promises to fire your metabolism and have you burning extra calories for hours. Read about when we tried it out

Cost: Class credits are normally £20 a class, or you can make a decent saving by taking a block of 10 (£180) or 20 (£325). You can also pay £275 for 21 sessions a month.



What is it: An awesome studio covering small group classes and individual personal training

Where is it: Old Street

Why would you go: A studio set up by Matt Lo, a fitness expert in strength and conditioning who aims to make fitness more accessible to people wanting to get fit. By running a series of structured fitness classes, and not just general circuit classes, Outrivals is working towards making classes a bit more like having an actual PT – only quite a bit cheaper.

Cost: The team have set up a nice range of pricing options ranging from £165 for a month of unlimited classes (£110 off peak) to a Flexi annual membership of £999  year. There’s also a couple of introductory offer: 1 week for £25 or two for £50. Well worth doing to see how nice this place is on the cheap.


Best’s Bootcamp/ Best Cycle

What is it: A HIIT studio that combine floor and weight exercises and treadmill work along with the Best Cycle spin studio

Where is it: Charing Cross

Why would you go: The exercise format is designed to give people an all-round workout in a short period of time. You get a bit of strength work, some muscle endurance (depending on which weights you choose), and a hell of a lot of speed work on the treadmill. The also have cameras on the class so that the trainer can always see you via big screens.

Cost: Sessions cost £20 for a single class with bulk offers available ranging from 10 to 20 class packages. You can also pay £180 for unlimited access for four weeks.


F45 Training

What is it: A HIIT studio that’s apparently pretty damn popular in Australia.

Where is it: Loads, all over London. Take a look here to find your closest

Why would you go: As HIIT classes go it’s one of the best we’ve tried. The facility is packed out with all the latest kit and they have some nicely planned out sessions focussing on different fitness goals as well as some nice heart rate software. Friendly bunch as well.

Cost: Prices differ based on location, but you’re looking at about £240 a month for unlimited use. 


Studio Lagree


What is it: It’s basically Pilates ramped up to the next level to include an intensive full-body workout.

Where is it: Near the Barbican, Canary Wharf and White City

Why would you go: If you want a workout that trains pretty much everything during one intense (and really tough) session, then this may be what you’re after. The method uses a machine called a Megaformer that looks like some sort of futuristic space weapon. A single trip combines core, endurance, cardio, balance, strength and flexibility training, and you’ll know you’ve worked hard by the time you leave.

Cost: A stand-alone pass costs £30 for one session. It gets cheaper if you buy in bulk though with a 10 class pass costing £240. An introductory class costs £15 – worth taking advantage of just to see the machines.


London Fields Fitness


What is it: Yoga, Pilates, Zumba, Circuits, HIIT, Boxing, Booty Camp, Warriors, Rebounding, HulaFit, Karate, Urban Escrima and Spin classes.

Where is it: Near London Fields station

Why would you go: An affordable, friendly studio offering a ridiculous amount of classes.

Cost: A class pass for January is currently £35. For spin classes it costs £10 a session, £40 for 5 or £75 for 10.
