The Training Zone - TTZ CrossFit®: Opinions
Fantastic experience: My first experience of crossfit was at TTZ. From day 1 Matt, Alex and the rest of the coaches made me feel at ease yet challenged me with the workouts. I would definitely recommend this gym to anyone. Amazing, friendly coaches and a great TTZ community.
Thank you Mumtaz for taking the time to leave this review! It’s been great having you as part of our community!
Fantastic experience: I joined TTZ as a complete beginner and I CANNOT express how much they helped me. The coaching was exceptional and the ability to feel like you get 1:1 coaching in a group setting is mind blowing and not easily achieved. I want to commend the guys for that. I felt welcome from the first trial session and somehow ended up at their members day competing. Alex looked after me the whole time and Matt was very patient with me during the two 1:1 sessions you get during the first month (which is such a bonus!!). I want to give Adam a special mention as he put up with me for most of the 6am sessions and his cues have helped me fix issues I've had for YEARS. (ankle mobility/ hips ect). His attention to detail, experience and excellence is undeniable. Also Ronan... To say this guy is an asset to the team is an understatement. His genuine kindness and smile every morning does not go unnoticed and he has a VERY bright future ahead of him. The members made me feel so at home too. Im quite the introvert so thank you to Jo and the rest of the 6am crew. What you guys have built as a facility should really be commended. I hope you realise the community you have built is something very special and it was an absolute privilege to even be part of it for a short space of time. I enlisted the team to help me ahead of moving to Bali and I have come here so much more confident. Thankyou. I will be back any opportunity when i'm in the UK. Love always Didi x

Fantastic experience: For the first time in my life, I am going to the gym regularly and enjoying every session and that is thanks to the TTZ team and members! Not only is the place welcoming and well equipped but the coaches are there to make your experience the best possible; they make sure your technique and skills are constantly improving and that you get the most out of every workout, whatever the difficulty is. I highly recommend the Training Zone, whatever your level of fitness or your goals are, you will find something for you there !
Thank you Flore! Pleasure having you and Adissu as part of team TTZ!
Fantastic experience: This is the best gym. Super friendly, very hard working & helpful coaches, great team spirit, supportive & always striving to help people achieve their next goal. Love we can have a coffee with friends too!
Thanks Rosanne! Pleasure having you as part of TTZ!
Fantastic experience: One of the best decisions my wife and I made in 2023 was joining TTZ. The coaches provide excellent guidance, creating challenging yet rewarding workouts. Whilst other gyms could be quite intimidating, at TTZ from the first sweaty fist bump, you're part of the community. TTZ is the place where lifting heavy stuff is a warm-up for lifting even heavier stuff and dropping weights feels like a mic drop. If you're into sweating, laughing, and occasionally questioning life choices TTZ is the place to be.
Thank you for the feedback Addisu. We love having you and Flore be a part of everything TTZ is!
Fantastic experience: This is a brilliant gym. Great instructors who keep you working with a safe technique whilst challenging yourself. People are amazing..strangest gym I've ever been to....people talk to each other! Love it!
Thank you Wendy! Great to have you as part of TTZ, let’s keep smashing those goals!

Thank you Nick for taking the time to share some kind words, we love having you as part of the team!
Fantastic experience: A great gym to work out in, friendly and knowledgeable coaches who push you to improve, and excellent coffee!
Fantastic experience: TTZ is a fantastic gym, well equipped and with some great coaches who create a very positive environment. There are group-based classes and also individual PT sessions - I have tried both, with Alex and Matt on different occasions. I have had different PT over the years so can honestly say that Alex and Matt are by far the best. They are passionate, friendly, encouraging and they listen to my aims and needs. As a result, my physical and mental well-being has improved. I have no hesitation recommending them.
Fantastic experience: The facilities, coaching and community at this gym are second to none. They also have really good coffee which helps... I've now been there for over a year, and as my first CrossFit gym I really recommend this to anyone who is just starting out and wants to try it or is established in working out/CF. I felt included and supported from the outset. Hands down the most enjoyable gym I have ever attended.
Thank you Zoe, it’s a pleasure having you as part of our community!

Fantastic experience: I’ve done CrossFit for a few years now. TTZ really encapsulates what CrossFit is all about; community, supporting each other’s goals and enjoying the process. Coaching and programming is 10/10
Fantastic experience: Crossfit may look tough but all the exercises can be scaled. Persistence and grit will always yield results A big Thank You to Matt, Alex, Adam, Hanna and Matt
Fantastic experience: I've know Alex a good few years now and not only is he a great coach but a fabulous athlete too with a wealth of experience in the world of fitness. I went down for my first session with Coach Matt last week and absolutely loved it. The facility is next level and the variety of classes offered opens the door to people of all ages and abilities. I signed up on the day and am looking forward to many more fun but gruelling times at the Training Zone :-)
Fantastic experience: A clean, modern and well equipped gym. The coaches are really friendly and never make you feel out of place. They are Really welcoming to beginners like myself and make time to teach and guide you through all the workouts. I would thoroughly recommend. Great coffee too!

The coaches are friendly and knowledgeable, and there’s a great range of classes to choose from. All in all, the gym is a really positive place to be, and I always look forward to my next class!
Fantastic experience: I think I was one of the first people to sign up at this new gym. Had my first session this week and it was great. The coaches are really knowledgeable and also really helpful. As a newbie to Crossfit they helped understand all the different moves and made sure I was doing them correctly. Definitely recommend
Fantastic experience: I joined as someone who had never done Crossfit before and I am so pleased I did. Matt and Alex have done a fantastic job setting up a great facility with a really welcoming atmosphere. Would highly recommend to anyone, whatever your fitness goal is.
Fantastic experience: I joined about 4 months ago as I always wanted to try CrossFit. I wasn’t disappointed. Alex and Matt are very welcoming and although it’s a fairly new gym it feels like they have been doing it for years. Great coffee too. Which is always a winner
Fantastic experience: This gym is amazing! Both coaches are friendly and professional. The gym has a nice atmosphere and sense of community. Great place to hang out for a coffee after a morning workout too!
Fantastic experience: I was in two mind whether to join a crossfit based gym but I'm so glad I look the leap! Both Alex & Matt are so supportive of your individual journey and building your own personal fitness level up pushing you but also making sure your super comfortable and not over doing it. No regrets and looking forward to growing with them
Fantastic experience: Having signed up before the gym opened it has far exceeded my expectations. With well structured classes for all levels and highly knowledgable instructors, Alex and Matt have created a lovely space to progress and achieve all fitness aspirations.
Fantastic experience: I have attended drop-ins as a guest and leave this review in that capacity. Fabulous box with a real community feel and excellent coaching. I’ve done quite a few drop ins at different boxes, enough to confidently say this place is quite special.
Thank you for you kind words Mark! It’s a pleasure having you in a class.
