BYS CrossFit®: Reviews

5/5 (17 Reviews)
Tammy Hill 1 year ago

Fantastic experience: I’ve been at BYS for about 3 months now decided to give it a try while I already had membership at another gym. I instantly loved it and switched, don’t get me wrong it’s hard work but that’s what I’m there for & I’ve never been to a gym that’s so welcoming and friendly it really does have a community vibe! If you’re looking to be challenged every time you enter the gym & be constantly learning & progressing no matter if you’re a beginner like me or experienced give it a try you won’t regret it!

Fantastic experience: Thanks Tom! I’ve really enjoyed getting back into CrossFit; I’ve become fitter and the many little injuries I had have all improved. You gave me loads of tips which have improved my form and efficiency which will stay with me. Thanks a lot!

Fantastic experience: Having been dubious about CrossFit for some years I finally plucked up the courage to join BYS. I’m annoyed that I waited so long!! The instructors and members are inspirational, knowledgable and helpful. Real team community. I still haven’t got a clue what I’m doing but I love it.

Fantastic experience: If you are looking for a welcoming, encouraging environment to train BYS is for you. Regardless of your levels of fitness you will be supported, encouraged and backed to constantly challenge yourself and improve - whether a terrified beginner or a season Crossfit pro). Tom, Chloe, Nikki and the rest of the coaching team have a fantastic knowledge of all things Crossfit and will always welcome you with a smile (even at 6am). If you haven't tried it you should...might change your life.

Fantastic experience: Only a month and a half in and I couldn't be happier. The community, support, and coaching from everyone there is great and it's just such a fun and relaxed place to be no matter your skill level. 110% recommend ️‍♀️

Sebastian Titheridge 2 years ago

Fantastic experience: Amazing box! And even better coaches lovely atmosphere and everyone so friendly and the session was great!!

Florian S 2 years ago

Fantastic experience: 2 Months in and I absolutely love it. The head coach (Tom) just came up with a new 6 category system improving your flexibility, strength and general fitness, which pushes you towards great progress. Don't be afraid though! Everything is scalable and doable as beginner. Beyond that there are team workouts and many cool events to get to know each other, hang out and have a lot of fun. Make sure to say hi, join for a free tryout session and see for yourself!

Ian Simpson 2 years ago

Fantastic experience: What an awesome gym! After rupturing my achilles, I was nervous about returning to exercise. The coaches and therapy team are so knowledgeable and scale movements that suit the individual. The community that BYS has created is friendly and supportive and the members really like to see each other better themselves. Couldn't recommend highly enough!

Darren 2 years ago

Fantastic experience: First free 'taster session' for my teenage daughter (14yrs old)! Bloody excellent. Staff are very knowledgeable, polite & friendly. I highly recommend this gym for any parent who wants to encourage their child to keep fit & stay healthy.

Tyler Strange 2 years ago

Fantastic experience: Friendly, non intimidating environment. Great coaching on hand to help you learn from a complete beginner or catering to more experienced individuals. An excellent crossfit gym.

Hayley Moseley 2 years ago

Fantastic experience: This place is addictive! Have been a member for less than a month. I never dread a workout and always feel like I have achieved something when I leave. Do sign up. You Will not regret it
