Fantastic experience: If Im not eating, napping or walking the dog Im at 13. And theres no other place Id rather be. I joined 2 years ago and kick myself that I didn't join sooner. Its made me fitter and stronger than Ive ever been but above all of that, my brain has never been in such a strong place. All of it is down to the insane members/friends and the incredible coaches!! I would recommend 13 to anyone, regardless of ability or experience! Bite the bullet and I promise you wont look back!
Fantastic experience: I was always intimidated by the idea of CrossFit. This time I managed to remove my mental block and go for the foundation course and haven't looked back since. I used to get jitters before attending any class, but I always felt happier after the class. It's been almost 6 months and I couldn't ask for the better, more supporting, easy going, and most welcoming community. To anyone who's remotely thinking of CrossFit, just go for it. You will not be disappointed.
Fantastic experience: I absolutely love coming here!! The coaches are full of knowledge and the community support is unrivalled! Not to mention our program is awesome, covering all movements and catering for all levels of fitness ⚡️
Fantastic experience: I love this place! The variation of workouts mean that you never get bored, the small classes give you PT level support for every single session & the members you train alongside are the friendliest and most supportive group of people you could ever wish for, even at 7am!
Fantastic experience: I started CrossFit as I felt like a needed a new challenge and wanted to get more in to ‘weight’ exercises and CrossFit felt like something that was definitely out of my comfort zone that would really test me. From the first minute I popped my head in to CrossFit 13 I have been constantly amazed by the welcome and friendly nature of everyone. It felt quite daunting making that first step but I really had nothing to worry about, there’s such a great family atmosphere! Make that first step! From the outside CrossFit can appear an extreme form of exercise but it truly is for everyone, and the set up at CrossFit 13 is perfect to allow for that.
Fantastic experience: I joined CrossFit 13 on a recommendation from a member, I am so pleased I did. It’s not just a gym but a community. Everything about the place encourages you to go and train, from the coaches to the members.
Fantastic experience: The BEST community, everyone is so friendly and welcoming. If you want to get fit and make a bunch of like minded friends this is the perfect gym for you. Emily (the owner) puts her heart and soul into the gym, and is constantly improving the service she provides for her members- it’s clear she really cares about each and every person. All levels catered for by experienced coaches
Fantastic experience: The most amazing gym with the most amazing people. This place has completely changed my life! If you’ve ever been interested in trying CrossFit, this is the place for you. The coaches and owner are SO passionate, she puts her all into the gym and her members. Imagine training and hanging out with your best mates everyday…
Fantastic experience: CrossFit 13 is one of my favourite places to train. From day one I was made to feel welcome, not just by the team but the community of people that train there also. The facilities are great, and the coaching is second to none.. I’d recommend this gym to anyone.
Fantastic experience: CrossFit13 has changed our lives in so many positive ways! The coaches are knowledgeable, friendly and always fun to do classes with, or open gym! The classes are always interesting, challenging and accessible to all. We feel fitter, stronger, leaner and more confident than we ever have before and most importantly the community in and around CrossFit13 is so inclusive, friendly and supportive, what more could you ask for!
Fantastic experience: Crossfit13 is 10/10 for me. The coaches are super helpful and genuinely care about you. They always have great ideas to help you improve on your technique with all movements and general fitness. The gym it’s self is great and has good equipment. The wod’s are brutal and the time to focus on your lifts are beneficial. The members are super friendly and very welcoming! You won’t feel out of place. If you’re considering a new box or somewhere to try/start crossfit then CrossFit13 is the place for you.
Fantastic experience: I had the pleasure of joining CrossFit13 over three years ago and I must say, I was thoroughly impressed and have never looked back. From the moment I walked in, I was greeted by a warm and welcoming staff who were eager to help me get started. The trainers were knowledgeable, professional, and really took the time to explain each exercise and ensure proper form to prevent injury. The group classes were challenging, but also fun and motivating. . Overall, I highly recommend CrossFit13 to anyone looking to improve their fitness and well-being in a supportive and positive environment. Thank you, CrossFit13, for a great experience!
Fantastic experience: I am a regular gym goer, working out 5 times a week on my own in the free weights section. When COVID-19 hit I was unable to work out or even get near any weights for about a year. Crossfit had been suggested a few times to me by a work friend. Lucky Crossfit13 is situated close to where I live so I signed up thinking it would be short-term until things got back to normal. More than 2 years on and I am still there. Everything about Crossfit13 is amazing, the coaches, equipment the workouts. It's a great community environment with everyone motivating and helping each other out so that we can all achieve our best. There is even a great social side to Crossfit13 with drinks and meals out in our off time. I have met a lot of great people and made some good friends. High recommended. Give it and go and see for yourself.
Fantastic experience: CrossFit 13 Pros: • Great coaching and support no matter what your experience or ability is. • Coaches will support people with injury and guide you through scaling down to prevent further injury but still being able to participate. • The work outs/ programming is probably the best I’ve seen or experienced producing results for all members. • Community focused and produces some great social events for all. For new people living in the area it’s been our support and helped us find our feet and make friends in the area. • Top quality equipment that’s maintained to a high standard, I have probably visited most gyms in the area and none have been as clean or had equipment half as good. • There’s more rowers then Ski ergs (Worst machine ever made) Cons: • Think I’ve nearly died during workouts three times (at least) since I’ve been a member • There’s usually a coach to catch your pain and suffering mid work out on camera • They don’t have Guinness on tap • They don’t show the Rugby • Going to the toilet after Ben • Ski ergs • Burpees
Fantastic experience: After years of training in regular gyms I became pretty bored. But Crossfit is something that constantly evolves and constantly challenges you in so many different aspects of fitness, from cardio to strength to gymnastics. But the very best thing about CrossFit in general is the incredible community atmosphere that comes with it. CrossFit 13 has this perfected. An incredible environment that encourages & educates & supports all of its members across all levels. The social aspect of this place is infectious, I’ve made friends here with people I probably wouldn’t normally get to meet. Try it.
Fantastic experience: Amazing coaches, great community. Highly recommended.
Fantastic experience: I am new to CrossFit but honestly Brain and Julie made it easy for me. The whole team is really helpful and they willing to help. Brain is a great Owner and also a coach. I will totally recommend them.
Fantastic experience: Great friendly team and will help you reach your goals
