‘Best Fitness Instructor’ and ‘Best Yoga/Pilates studio’

Hi! I’m Katrina, Head of K Fit and self-confessed exercise addict. At K Fit we’re all about getting people up and active, and implementing an active lifestyle. I love using exercise not only for a healthy body, but for a healthy mind. After a few tough experiences and confidence knocks I’ve realised how important exercise is for me and I want to help others feel the same, and notice the positive impacts that an active lifestyle offers.

We have a variety of exercise styles for you to try, so that whatever your fitness goal is it can be achieved on the K Fit programme.  All our classes are mixed ability, so whether you have experience or are just at the beginning of your fitness journey, you can achieve a good workout which is appropriate to your level.

There’s no time like the present; have a look around and boost your fitness lifestyle with K Fit!

If you’re unsure which workout will suit you best then just drop me a message and I’ll be happy to help.

This week I am celebrating 7 years of fitness instructing in St. Neots!! 😍🎉

Wow, it is so true that time flies when you’re having fun. I can still remember my first ever Zumba class at Bushmead School...I’d made and printed some terrible flyers and dropped them locally, unsure of if anyone would turn up (except my mum and Sue!). The height of the Zumba craze meant that word had got out, and despite my lack of marketing skills 29 people crammed into the hall...and the booty shaking commenced!! 😁👯‍♀️

That was the beginning for me, and I can hand on my heart say that I have loved every single second of my fitness career since. 💕

From ‘Zumba with Katrina’ to K Fit, I’ve built and grown a foundation of fitness classes with ethics that are important to me - being healthy and happy, having a welcoming and friendly fitness environment, not taking things too seriously and absolutely NO judgement. Im proud to say that hard work pays off, and leaving my full time job 3 years ago to develop K Fit further was the best thing I ever did. 🤩

I am celebrating my 7 years with an 🌟 Anniversary Zumba Class! 🌟

Zumba is where it started and will always be my class for Ultimate Happiness 😌💕

Join us tomorrow for Zumba Through the Ages, and relive your favourite tracks!! 😍

At Bushmead School
£6 per person (or £4 if you came on Monday)

Get ready for cheesey moves, memorial moments and a whole lot of shimmying 😁 I cannot wait to reminisce!! If you have any requests pop them below too, I’ll see what I can do ☺️⬇️

Happy birthday Zumba!!
