Reformer Pilates in Grantham

If you've been searching for reformer Pilates in Grantham, the wait is nearly over.

FLOW Reformer Studio - the award-winning boutique Pilates group already established in Bottesford and Bingham - is opening its largest studio yet inside The Keep at The Old Barracks on Sandon Road. It's one of the most striking buildings in the town, and it's about to become the home of structured, expert-led reformer Pilates for Grantham and the surrounding area.

Here's everything you need to know, including how to get in first...

A Studio Unlike Any Other: The Keep, The Old Barracks

The building FLOW has chosen for its Grantham home is no ordinary commercial unit. The Old Barracks is a Grade II listed building on Sandon Road, designed in 1858 by county surveyor Henry Goddard for the South Lincolnshire Militia. With its castellated Gothic frontage, original stone archway, and distinctive twin turrets, it's one of the most architecturally significant sites in the town.

Over the years, the building has had quite a life. It served as a military barracks and rifle range, housed a military hospital treating wounded soldiers during World War I, and in its 1960s heyday operated as a music venue — with names including The Who, The Hollies and The Glenn Miller Band having graced the site. Today, the beautifully renovated complex is home to a community of health and wellness businesses, making it a fitting setting for FLOW's new studio.

The quadrant currently hosts Kirks Vets Grantham, one of South Lincolnshire's most established veterinary practices (based at the Old Barracks for many years), and The Keep Clinic — a private orthopaedic and musculoskeletal clinic run by specialist consultants from MSK Doctors. It's a cluster of trusted, professional health services — and FLOW fits naturally into that community.

Becki Cowling, founder and head instructor of FLOW, describes the moment she knew it was right:

"When we first walked into The Keep, we knew it was the right space for our third studio. There's parking right outside, and the building has a real 'wow' factor — it feels opulent, calm and welcoming. It's the perfect place for people to come, exercise and take time for themselves."

The studio is located just a short walk from Grantham town centre, opposite Grantham College, and within walking distance of the River Witham. Free on-site parking is available, making it easy to attend a class before work, in your lunch break, or during the day.

What FLOW Grantham Will Offer

The Grantham studio will be FLOW's flagship location and its largest to date, with 12 reformers giving significantly more flexibility than the existing studios in Bottesford (8 reformers) and Bingham (11 reformers).

Classes will cover:

• Small group reformer sessions:  beginner, intermediate and mixed-ability levels
• Jumpboard classes:  a dynamic, low-impact cardio option using the reformer footbar
• Pregnancy Pilates:  structured courses for expectant mothers
• Postnatal Pilates:  returning to movement safely after birth
• Private and physio-led sessions:  tailored one-to-one coaching
• Workshops and corporate hire
• Reformer Pilates Instructor Training

Every class is kept deliberately small. FLOW's philosophy has always been that reformer Pilates should feel coached, not crowded, and that doesn't change with a bigger space.

The Instructors You'll See in Grantham

FLOW's Grantham studio will be led by some of the most experienced instructors in the network. Here's who you can expect to see on the timetable.

Laura — Physiotherapist 

"Reformer Pilates has the rare ability to meet people exactly where they are. Whether someone walks in as a complete beginner or an experienced mover, the reformer adapts to them - and that's what makes it so effective, and so rewarding to teach."

With over two decades in health and fitness, and backgrounds in both personal training and Pilates instruction, Caroline brings a depth of knowledge that shows in every class. She's known for creating sessions that feel genuinely challenging without ever feeling unsafe.

Jess — Senior Instructor

"What I love about teaching reformer Pilates is watching people surprise themselves. They come in not sure if it's for them, and within a few classes they're stronger, they're moving better, and they can't imagine their week without it."

Jess holds Level 3 qualifications in both Mat Pilates and Reformer, and brings expertise in strength-based training alongside a warmth that makes her classes approachable for all levels. She's a key part of the FLOW team that launched the Bingham studio.

Flo — Instructor

"My ballet training taught me that movement should be precise, intentional, and always connected to how your body actually feels. That's exactly what I bring to the reformer - technique that serves you, not just technique for its own sake."

Flo trained at the Central School of Ballet in London, graduating with a First-Class degree. Pilates was central to her professional training, and she now brings a modern, evidence-informed approach to her teaching - combining exactness with genuine encouragement.

Natasha — Senior Instructor

"I've seen firsthand what consistent reformer Pilates can do for someone's strength, confidence and quality of life. That transformation never gets old. It's why I keep showing up every week, and it's why our members do too."

Natasha has managed fitness centres across Leicestershire and taught group exercise for many years. She holds a Level 3 Mat Pilates qualification and is deeply passionate about guiding people at every stage of their fitness journey.

Why Grantham Has Been Waiting for This

Until now, there has been no dedicated boutique reformer Pilates studio in Grantham. Reformer Pilates is one of the fastest-growing fitness categories in the UK, yet residents of Grantham and surrounding villages like Barrowby, Great Gonerby, Harlaxton and the Vale of Belvoir have had to travel to access it.

FLOW's arrival changes that!

The studio is designed to welcome people who have never set foot on a reformer, as well as those who are already experienced and looking for a high-quality local option. As Becki puts it:

"We've always believed that reformer Pilates should be accessible - not intimidating. The Grantham studio is our biggest space yet, but the approach is exactly the same as it was when we opened with eight reformers in Bottesford. Small groups, expert coaching, and a community that genuinely supports each other."

FLOW's Track Record

FLOW didn't arrive in Grantham without a story behind it.

The studio started in Bottesford with a simple idea: create a space where people felt genuinely supported from their first session, not just shuffled through a large class. That model worked. Classes filled quickly. Members got stronger and stayed. Waitlists became the norm.

That organic growth led to the Bingham studio... Larger, with a broader timetable, but the same small-group ethos. Now, with two established studios, a 2025 Quality Business Award for Best Pilates Studio in Nottingham, and an instructor team that includes two physiotherapists, FLOW is bringing that same standard to Grantham.

The instructors at FLOW hold Level 3 and 4 qualifications in Reformer Pilates, Mat Pilates, Personal Training, and related disciplines. Several hold physiotherapy degrees. The team also includes a qualified sports masseuse and a former ballet graduate. It's a depth of expertise that is rare in boutique fitness, and it shows in the quality of coaching members receive.
