Barry’s Bootcamp

Best For: A high-intensity workout

Often billed as one of London’s toughest workouts, Barry’s Bootcamp was born in Hollywood, making its way to the British capital in 2013. In its notorious red rooms, you’ll be put through your paces in a 55-minute workout which includes both cardio and strength training. Half the class is performed on the treadmill, where you’ll be led through a series of HIIT-style intervals, while the other half involves both weighted and bodyweight exercises on the floor. Throughout the week, different classes focus on different body parts – there’s lower body; upper body; chest, back and abs, and so on. It’s notoriously challenging, but fun playlists and encouraging instructors keep motivation high. Plus, you’re offered a range of options throughout, from beginner to advanced, and can adapt your speed and weights accordingly. Afterwards, enjoy luxe changing facilities and reward yourself with a well-earned post-workout shake. Training for a big run? Check out the programme of technique-focused classes running in partnership with sportswear brand Alo, featuring specific coaching for runners alongside tailored runs for milestone distances.

SoulCycle

Best For: Spin classes

After much anticipation from London’s spinning brigade, indoor cycling empire SoulCycle opened its first international studio in Soho in 2019. Since launching over a decade ago, the brand has developed a massive cult following in America, with clientele including the likes of Beyoncé and Michelle Obama. It’s also inspired a new wave of spin studios this side of the pond, including Psycle, 1Rebel and Boom Cycle, all featuring pumping music, motivational instructors and the concept of riding to the beat. But SoulCycle promises something different: a mind-body-soul experience, which is not just about burning calories – although you’ll certainly do a lot of that too. Each studio has its own crystal, classes are candlelit, there’s a lot of talk about energy, positive mantras and getting into the zone, and (most importantly) phones are banned. Be warned: you might be asked to high-five your neighbour. But it seems Londoners are hooked – the 63-bike strong classes tend to completely fill up.

1Rebel

Best For: Immersive spin classes

Bright lights, a stage, multi-tiered flooring: 1Rebel’s Ride studio in Victoria is more like a theatre than a gym. And in many ways it is a performance, but one where the 80-bike strong audience must take part too. A celebrity-style spin instructor is elevated on a platform, encased within a circle of lights. The 3D sound system, Ibiza-style lighting and special effects transport you to another world – one where exercise is actually fun.

There are 12 1Rebel gyms across the city, spanning East to West.

KARVE

Best For: Transformer Pilates

London’s coolest new fitness spot is KARVE, a New York-inspired studio on High Street Kensington pioneering the Transformer Pilates method. It’s low-impact – but don’t let that trick you into thinking it’ll be easy. A step up from classic reformer, this 50-minute workout is designed to ‘karve’ the body and mind, using time under tension techniques, pulses and isometric holds to initiate a serious burn. Expect a intense session of tricep dips, side planks and lunges performed on the machine, with a breathing meditation at the end to re-establish the mind-body connection.

Where: 198 Kensington High Street, London W8 7RG

UN1T

Best For: Circuit training

‘We train as one’ is the mantra for fitness studio UN1T. Prepare to be pushed out of your comfort zone as you work as a team in a series of cardio, strength and mobility focused classes in a circuit format, with 12 different stations for participants to work around – from weight lighting to rowing machines to climbing planks. Rumour has it if you’re spotted having a break the class will be punished with five burpees, so it’s certainly not one for the faint-hearted. Despite this there’s a really friendly atmosphere and the team-style structure is great for motivation – you’ll certainly leave on a high (if a tad exhausted).

The Engine Room

Nobu Pilates

Best For: Pilates classes

A large, light-filled room overlooking Portman Square, Nobu Hotel’s studio is a Pilates enthusiast’s dream: think reformers, Cadillacs and towers, with wall-to-wall mirrors and plenty of space. The lovely Marsha Lindsay runs the show here, offering three signature classes exclusive to Nobu: Power, Precision and Pure Pilates. Power offers a HIIT-style class, which incorporates jump-board choreography and up-tempo exercises, while Precision is a sculpting class focusing on targeting specific muscle groups. Pure, meanwhile, honours the original style of Joseph Pilates, reinforcing the importance of a strong core and good posture. Afterwards, refuel with a cold-pressed juice and snack from the next-door café – or head downstairs for some well-earned sushi.

Where: 22 Portman Square, London W1H 7BG

Paola’s Body Barre

Best For: Barre workouts

Head to one of Paola’s 50-minute barre classes to feel the burn like never before, in muscles you never knew existed. A mixture of Pilates, cardio, strength, ballet and dance-based moves, classes are harder than the average barre class. But your body will thank you for it – after just a few sessions you’ll feel leaner, stronger and more toned. There are a number of different variations of the class, but most incorporate the barre, as well as weights, balls, resistance bands and other exercise paraphernalia, with plenty of squats, pulses and planks. If you want to really challenge yourself, go for PBB Burn, a step up from the PBB Signature class notorious for its ‘burn factor’ – you can burn up to 700 calories in a class.

Where: Multiple locations

Sweat by BXR

Best For: Climbing cardio

Though the Marylebone BXR studio is members only, anyone can attend the pay-to-train classes at boutique fitness studio Sweat by BXR. The flagship is located beneath BXR London, and boasts a VersaClimber studio with state-of-the-art machines. This is a high-intensity cardio workout which mimics the feeling of climbing: expect to burn hundreds of calories and feel it everywhere. Each climber is equipped with a Bluetooth touch screen meaning you can record and save workouts, and watch how you progress week on week. Surround sound and LED strip lighting, plus a killer playlist, gives the class a fun, immersive feel too (and helps distract from the pain).

Pilates Squared

Best For: Reformer pilates

The usual dread of going to a new gym has entirely evaporated by the time you roll up to the elegant townhouse in a leafy South Ken neighbourhood where the Pilates Squared studio is located. A large bay window lights up the intimate space where the highly-trained experts walk you through the hi-tech apparatus which includes Reformer machines and a Cadillac (the rather terrifying-looking metal frame with additions to help you stretch in all the right places). This is bespoke fitness at its very best – each new client receives an individual consultation from which a personalised program is devised to help them meet their goals.

Classes never have more than three people and the studio specialises in one-to-one training, so this is the place to go for expert individual attention. The focus is on perfect alignment, stretching and strengthening through Pilates which is beneficial for weight loss, a more toned body and even rehabilitation for injuries. Book in for a private session with founder Caron, or the charming and attentive Hakan who puts you immediately at ease (despite his military background). A true gem in London and needless to say, clients are lifelong and fiercely loyal – and the results obvious after just a few sessions.

Where: 27 Emperors Gate, London SW7 4HS

F45

Best For: An intense HIIT workout

With an ever-growing number of studios across London, you’ll likely find an F45 on your doorstep or near your place of work. The sessions are hard and fast, and combine HIIT with circuits and functional training. The result is a 45-minute class that will burn fat, build lean muscle and leave you drenched in sweat. There are 31 different classes to choose from, and with different circuits which you are guided through by on-hand instructors plus technique demonstrations shown on screens, you certainly won’t be bored.
