What is the Define method

Our unique classes use body-burning, stretching and strengthening systems to help you achieve a strong, lean, sculpted body through an evolving mix of fitness exercises, simultaneously combining strength training and cardio so not only are you burning fat you are building long lean muscle.

DEFINE uses an intense mix of isometric moves whilst incorporating cardio infused sequences throughout the class to keep your metabolism high. While we stick to a formatted class within each concept, no workout is alike because we change up the choreography in every class to keep your muscles guessing.

The biggest benefits of our DEFINE classes are improved posture, muscle definition, weight loss, increased flexibility and reduced stress. DEFINE is designed for all fitness levels, so as long as you have a positive attitude, we promise to give you that burn and shake that leaves you wanting more.

Our focus on alignment and strength results in better DEFINE posture, better DEFINE movement, and most importantly a better DEFINE YOU.

Our goal is to DEFINE a Stronger, Healthier, a more Inspired version of YOU.

I have a huge passion for the arts and fitness industry, there is nothing I enjoy more than seeing enthusiasm and happy faces with what I can bring to help achieve your goals. The body is an incredible thing, so helping others discover what it can do and how it can be worked is amazing! This may come from me also being a Sports Masseuse.. another part of my life that i love!

Straight from school into 3 years of performing arts training then out into the big wide world as a professional dancer at 19. I was completely stoked with the jobs I landed - touring, stage shows, music videos, commercials. My highlight and biggest achievement was in 2014, Lily Allen "Sheezus" World Tour. For six years the fun, travelling and visiting places I had never imagined to go was epic! 2017 was approaching and deciding I wanted to be a little closer to home more often, a new career path was emerging. My love for fitness was turning more into a passion and I decided to run with it. Straight into studying my Level 2 fitness instructing qualification whilst training at various studios to become an instructor in different concepts. My brain was mashed but it's so worth the outcome! I haven't looked back and how lucky am I to still love what I do, something that is my job but in no way feels like a job.

Favourite Quote/Mantra?

- I'd rather be sore than sorry

Do you have a morning ritual?

- Drink water before anything! And complete my skin care routine or I refuse to leave the house.

Favourite workout wear?

- Nike. Always Nike. Although after a recent lululemon purchase I'm worried my morals could change.

Master Trainer

New Zealand born and I come from a professional contemporary dance background. After graduating from the New Zealand School of Dance I toured with some of the leading companies in New Zealand such as Black Grace, Okareka and The New Zealand Dance Company. I moved to New York City to pursue an artistic career through guest performance and working on music videos. Now residing in London I made the natural shift into the fitness realm as a qualified Personal Trainer. With a passion for movement, from travelling, living abroad, dance and wellbeing I draw on my varied background to build, develop and communicate the importance of moving!

Do you workout while on holiday?

- (As I write this on holiday in New York sitting outside soulcycle..... the answer is yes)
Depends on the location, whenever I go back to home to New Zealand I try and keep up a routine. But put me on a beach and I may skip on the routine!

Any hidden talents?

- I wish I had a good party trick, like could sing or play an instrument. The best hidden talent I've got is I can fold a T-shirt in 3 moves. Watch out y'all!


Lindsey Pryor


I found my love for all kinds of dance at a young age so after school I headed to Northumbria University and completed a BA Hons Degree in Dance Choreography. While studying, I was a member of the North Stars Cheerleading Squad where we got to compete nationally. Once finishing University I was lucky enough to perform all over the world with The International Allstarzz as well as dance for brands such as the BBC, MTV and ITV.

While training I found my love for fitness and so decided to follow my passion for teaching. I became a qualified Level 2 Cheerleading Coach and now coach the Elite teams and School of Cheer at Saracens Sport Foundation. I also trained as a Level 2 Fitness Instructor and teach a variety of classes around London. I feel so lucky to be able to teach so many amazing people and help them feel better in their mind and body. I’m so excited to be a Define Instructor and spread the ‘long, lean & defined’ message all over London!
