Aldgate-based FLY LDN is the antithesis of the rave-inspired HIIT class. Carefully curated playlists and immersive cinematic visuals of Himalayan mountain ranges, crashing ocean swells and sun-filled forests replace flashing lights and blaring music. The rolling, large-screen landscapes create a low-stress and multi-sensory environment that strips yoga back to its roots. Small class sizes and hands-on instructors help you to master difficult moves and polish your poses - newbies will be transitioning into headstands in no time. Base Flow classes takes you through the basics; Flowlife is the signature class suited to those with moderate experience who want to deepen familiar postures; and candlelit hip-hop yoga is a high-energy (read: sweaty) remix of traditional vinyasa set to sick beats.

Say namaste to yoga 2.0 - this is futuristic fitness at its finest. The artist and creative brain behind ChromaYoga, Nina Ryner was inspired by the work of James Turrell, Carlos Cruz-Diez and Veronica Ann to create a space that uses colour therapy, stimulating soundtracks and harmonising essential oils to fit the mood and intention of the class. Sluggish souls should sign up for the Blue class, which aims to rewind the damage incurred by staring at a screen and focuses on repairing broken sleep cycles. Ramp it up with the Orange class to drench yourself in productivity-boosting sunrise hues (and sweat), then follow it with the Pink: Restore class, in which a sequence of six gentle stretches aids muscle recovery.

You'll find Fierce Grace studios in all of London's leafiest areas: Primrose Hill, Kilburn, Muswell Hill and Finchley, to name a few. Responsible for bringing bikram hot yoga to London in 1994, it offers classes that cover hatha, ashtanga and bikram styles in studios set to 38°C. You're guaranteed to get sweat - this is not the place to elegantly practice your lotus pose. The brave and bendy should book into WILD, a high-stamina, energy-demanding class which combines strength poses, HIIT sequences and core exercises with holds that are (literally) achingly slow. Pack a change of clothes; Fierce Grace makes every other hot-yoga class look like a walk to the pub.

Hipper than a macadamia-milk nitro-brew, Blok is all brutalist concrete, bare-brick walls and cast-iron pillars. Fusing fitness and design, its Clapton gym occupies a converted Victorian tram depot while the Shoreditch site features breeze-block sculptures from an artist in residence. It may look like an art gallery but Blok certainly isn't style over substance; more than 20 yoga and pilates classes are on offer, including from restorative yin yoga, squeeze-it-in-your-lunch-break pilates and hardcore power yoga sessions. Power Yoga L2-3 is as intimidating as its sounds and not for the flexibly challenged - we're talking complex inversions, breaking down mental barriers. It pushes usually unflappable yogis to their physical limit.

A simple space saturated in sunlight in Lower Clapton, Supply Yoga is a neighbourhood studio that hosts classes at budget-friendly prices. The studio has been built on the mindset that yoga can combat social isolation, reduce anxiety and provide emotional support. The studio is a firm believer that yoga has the power to enhance your mind, as well as your physical wellbeing. Profits from the classes go straight back into helping fund free yoga classes for community support services across London. On top of its weekly timetable, the social enterprise hosts regular workshops including Queer Yoga and Yoga for Anxiety, during which mindfulness techniques and breathing exercises are used to manage day-to-day city stresses.

At Tempo Pilates' edgy Shoreditch, Hackney and Convent Garden studios, reformer pilates is set to thumping beats that dictate the pace for the body-conditioning sequence. Catering for reformer pilates beginners or for those who have yet to brave the reformer machine - the medieval-looking torture contraption that you've probably seen on Instagram - classes allow you to master the core principles before moving you up to Tempo Pilates L1. The first part of the class follows the same routine each week, encouraging you to hone your technique, followed by 30-minutes of freestyle led by expert trainers. No two classes are the same, so you won't get bored or complacent. Short on time? TP X-Press is the bite size, 40-minute version that fits into your lunch break.

Is there anything more East London than The Refinery? Expect retro aesthetics, playlists packed with 80s tunes and a playful roster of workouts taken by some of the capital's most talented instructors. Sure, the class names err on the cringey side but Yoga Fit Flow adds a bit of fun into your monotonous fitness regime while Hip and Hamstring Heaven will have you sashaying your elongated limbs around like a Jane Fonda-goddess. It's not all leg warmers and screeching into your dumbbells, small-sized (no more than 12 at a time) hot yoga, hatha and pilates classes feature regularly on the timetable.

Housed in a former park-keeper's lodge with views over Southwark Park, theLodge is the kind of place you'd want to wander to on a Sunday morning, matcha latte in hand. The Scandi-inspired decor - exposed bricks, distressed leather, reclaimed wood - is the ideal backdrop for its punishing hot yoga and pilates classes. Tackle complicated postures and inversion in an Aerial Yoga class, with a routine of flips, tricks and spins that wouldn't look out of place on Strictly Come Dancing. Aerial Yoga Trapeze requires slightly more skill and fewer sequins - think of it as a TRX class but suspended in the air by a parachute-type fabric. Bring your own towel and enjoy a shower on site to enjoy full-size Aesop products and heated changing room floors.

As big a part of Dalston's Shacklewell Lane as the Hand of Glory's giant maypole, Yoga on the Lane has been providing refuge from city dwelling since 2012. Owner Naomi Annand is a former Royal Ballet dancer and has developed a breath-led style of vinyasa that's more results-driven than spiritual awakening. That being said, tired eyes do receive soothing parcels of lavender at the end of each session. Mats, blocks and straps are offered throughout and floors are heated - Annand really has thought of everything - so your morning savasanas won't leave you shivering. Book in advance; weekends are extremely busy and morning classes fill up quickly.

Heartcore has been West London's go-to yoga and pilates studio for what seems like forever - even the Duchess of Sussex is a fan. Intimate classes mean there's no slinking to the back, but with the trainers' hands-on approach, you'll soon see an improvement in your postures and definition in your baby abs. You'll hear pilates enthusiasts in the changing areas harping on about the custom reformer machines - and they're right too. The Rolls-Royce of reformer beds has been customised to fully engage your core and was built according to scientific athletic studies. It's a slick piece of kit, but do approach with caution; after a gruelling 60-minute session you'll be struggling up the stairs for days.
