Positive experience: Not bad

Mighty Jock Law Published on Google 2 years ago

Fantastic experience: Been a member here for 2-3 years now. Really good, friendly gym. Great coaching and very accessible. If you want to try CrossFit but are nervous about it, then I’d highly recommend dropping in for a taster and meeting the coaches and the other members. It’s really supportive and the workouts are tailored to what you can do and to help you progress. Good atmosphere - recommended.

Fantastic experience: I have been attending the box for almost two years. I’ve made some huge improvements in such a small amount of time with team Theta. Loving the variety and the intention of the programming. Thanks for making the box a joyful, collaborative and positive place to be.

Fantastic experience: I started CrossFit at 46 years old, so your not to old. I didn’t do any fitness before. So you don’t need to be fit to do CrossFit. I have become fit because of CrossFit. Training with other people around you is a great way to stay motivated. With coaches on hand to make sure you are using good technique.

Fantastic experience: Theta has really come to town with a bang as expected, bringing energy, good vibes, community spirit and some top coaching. The programme is brilliant and with all the fantastic coaches help, let’s everyone from different abilities move well, have fun and improve. Theta is the place to be ‍♂️.

Fantastic experience: The best just got better! Having spent a few months training here, I cannot recommend it highly enough. Refreshed, with new ownership, the direction and suitability of the classes are second to none. Having found CrossFit at the start of this year, it has been fundamental to my own lifestyle change and the most supportive community environment for any fitness level, age, shape or goal - a one stop shop for your health and well-being!

Fantastic experience: Handing over the box after almost 10 years, it had to be to the right group of guys and I knew that these boys would get it bang on. In a short space of time they have made their own, great community of people, great atmosphere, great coaches. I no longer own a CrossFit Box but I love being part of the CF Theta crew, it’s all about the fun and fitness. The classes are great and for all abilities it really is a for everyone.

Fantastic experience: Excellent place. Coaching & atmosphere is fantastic & anyone is accepted whatever level of fitness or age. I tried other gyms before I found CF Theta & this is more than just a gym. Book your free trial as I did ✅
