  • “Unlike other reformer classes where you’re mostly lying down, Reformcore gets you up and moving, and also adds dumbbells - so you’re sure to break a sweat.”

  • “The classes may be testing, but the experience is meditative and, for a fleeting moment, relaxing, with guided meditation bookending fifty minutes of strength work and stretching.”

  • "As a former dancer, I expected an easy class, but it was one of my toughest yet—with slow, deep movements that revealed areas of my fitness needing work and helped restore flexibility I’d lost over the years."

  • “Reformcore is perfect if you only have a couple of hours a week to exercise but you want to get stronger quickly.”

I’ve been going to boomcycle for two years now. It’s got a great atmosphere and the teachers are the best: energetic, helpful and they bring the best playlists.
Specifically recommend AJ and Martina!

Had a bit of a nightmare when trying to book, confusion between accounts, apps and branches made for it all to be rather complicated. Once I arrived to the studio, I missed the class by a few minutes and was moved into the following class. Arriving again, there was confusion on whether I was moved as my name wasn’t on the list. Antonia was absolutely incredible from start to finish, from over the phone, to on the app and in the studio, she really turned the entire experience around for me. One of the warmest welcomes I’ve received into a studio, which is hard to come by nowadays.

The class itself was great, the studio is clean, bright and easy to navigate. BURN delivered on all it had promised!

Thank you again to Antonia and the rest of the team, I will most certainly be back and it was her hospitality and pro-solution reassurance which made this experience complete.

Loved the spin class, super fun but also a great workout! Left feeling great. Would definitely recommend
google
Consistently good
teachers
Challenging enough classes
I like 50 min classes
A decent amount of classes on the scheduled in Battersea would be great to have the mid morning and early afternoon classes back at st Mary’s axe and shoreditch.
Nice venue and lounge area
I’ve been to most reformer studios in London over the last 14 years and am enjoying being a frequent visitor to reformcore.
google
Love them I wish they had barre classes at that location as well would've been perfect

Been a big fan of boom cycle for years but Battersea has stolen my heart as my new fave. Big shout out to Izzy, holly at reception for being so attentive, accommodating and welcoming. Instructor Amy is exactly the vibe you want for a mid week slump, she gets you out of the saddle and feeling euphoric.

Frequently asked questions

  • What is Reformcore?

    Curated for power, strength and core-fitness, Reformcore elevates the Reformer Pilates experience to be more efficient and effective than ever. Reformcoreworks you harder, using state-of-the-art Reformer Pilates machines and equipment to build muscular endurance and strength.

  • What is the difference between Pilates and Reformer Pilates?

    There are two main types of Pilates – mat work Pilates and Reformer Pilates. Both are based upon the premise of controlled movement against some form of resistance. In mat work classes, all you’ll need is yourself and a mat (gravity will provide the resistance). In Reformer Pilates classes, you are based on the reformer bed and use various pieces of spring-based equipment for additional resistance. 

    Both mat and equipment Pilates, when practised with consistency, will improve your strength, coordination and mobility. There are many health benefits, such as injury prevention and improved recovery and performance for those who are doing sports training or practising yoga. 

  • What’s the difference between Reformcore and regular Reformer Pilates?

    Reformcore is a high-energy class with playlists designed to energise you whilst bringing your mind to laser focus resulting in a kind of meditative state. In Reformcore, you will be working to your maximum for most of the class using lots of repetition to build muscular endurance and strength.This format uses tiny isometric contractions at the deeper part of full range movements to isolate and strengthen muscles. We top off each section with a finisher to get the most out of our muscles each time.

  • What can I expect from a Reformcore class?

    This is a fast-paced class that delivers a deep-burn and a big endorphin in the end. Expect to get your heartrate up early in the class feeling immediately challenged.

  • What is Reformer Pilates good for?

    Reformer Pilates offers a full suite of physical health and mental wellbeing benefits, including: 

    • Improved overall muscle balance in the body and creates a long and lean muscle tone 
    • Stress reduction and detoxification 
    • Improved stability and alignment of the major joints in motion, reducing occurrences of injuries 
    • Promoting a more efficient and supportive core 
    • Encouraging efficiency of movement and improves performance of day-to-day movement and sports 
    • Improving the function of the lungs and circulation 
    • Aiding the prevention of certain health conditions 
    • Focuses on movement and breath, encouraging meditative states 
    • Increases movement awareness, resulting in safer use of the body and fewer injuries 
    • Better alignment, posture and more efficient use of the body 
  • Is Reformcore good for beginners?
