K1 Fitness: Opinions
Fantastic experience: Does this gym have boxing stuff?
Yes we have a boxing ring, heavy bags and aqua bags.
Fantastic experience: I love training, particularly boxing, I am 68 years old and have been into fitness all my life. However, I was going stale, losing my enthusiasm and needed a big change up. Thank goodness for David and his excellent team of Pt's It is different to the norm and offers a great varied option of training. I am loving my training again.
Hi Jan, amazing to hear, we are so pleased you are enjoying your training again.
Fantastic experience: Great place to train with with like minded people,
Thanks James, always a pleasure to train you, see you again soon.
Fantastic experience: First of all K1 is like no other gym, the team at K1 are exceptional; from start to finish everyone who works here is fully on board to help everyone (and me) reach their goal. Meeting weekly with my personal trainer means I can tweak my routine to get optimised (visible) results. The one to one and group sessions are great for motivation and keep me on track, the sessions at the gym change often so you can never get bored. I have never felt so encouraged to stay fit. Huge thanks to everyone who works at K1, great to be a part of something from the start!
Hi Nina, thank you so much for your kind words! we love training you, see you again soon at K1.
Fantastic experience: I’ve been a member of a gym for over 20 years now and K1 far exceeds anything I’ve ever experienced. It’s more than just a place to go and exercise and you really feel like David and the rest of the team wants to help you achieve your goals - In the past few months I’ve made more progress than at any other time.... With its mix of small group training and classes you get to know both the team and the other members....it helps you feel part of the community and makes every session fun!! It’s incredibly well equipped yet doesn’t have the usual range of weights machines you find in commercial gyms....the end result is you actually work harder and have far more variety to your routine. I can’t recommend this place enough - go give it a go, I bet you will be converted just like me!
Thanks Andrew, that means a lot, an absolute pleasure to train you.
Fantastic experience: I cannot recommend K1 highly enough! The trainers are friendly, professional and really take into account any injuries or goals you may have. The sessions are personalised and the friendly atmosphere makes every visit enjoyable!
Thanks Rebecca, glad you enjoy your training at K1!
Fantastic experience: Where do I start - this gym is what I think about when I think of the perfect personal gym. Uncluttered, not intimidating and small groups makes for more personal interaction with the trainers. Specific injuries are catered for and exercises are tailored around these and you don't feel that your personal needs are ignored. The classes are intense for every level athlete, the workout combinations are diverse and fun (even when you're struggling to finish that last set!). My most favourite part of the week is my Rumble class with John!
Thanks Jasmine, glad you are enjoying it all, Rumble is one of my favourites too :)
Fantastic experience: This is more than a gym. The coaches are there to help and encourage you through any of your goals. The atmosphere is non intimidating and instead one that inspires you. Great equipment and a state of the art facility. I have finally found somewhere I really enjoy going to!
Thanks for the kind words Benji, you are a pleasure to train!
Fantastic experience: A brilliant studio with a fantastic personal training team who are truly dedicated to helping you achieve your goals. I can’t rate the whole team highly enough.
Thank you Hayley :)
Fantastic experience: Simply the best atmosphere and training I’ve done. Battling back from a severe illness I hadn’t done any exercise for almost 10 years and was starting to feel uncomfortable with my weight and appearance let alone not being able to ride my bike for any length of time (I’m in the Bicycle Trade). David and his Team of trainers have made me feel super comfortable at K1 and helped me enormously. I’ve become stronger, a lot leaner and feel much better physically but more importantly I’m mentally stronger. So if you want to change your life for the better and train in a place with no ego’s then give K1 a try, you won’t stall in your training like a conventional gym and you will get out of it what you put in and more. Couldn’t be more grateful to them.
Thanks Mark, great to hear and we love training you, see you soon.
Fantastic experience: Love it! Great classes and small group sessions - this setup works so much better for me compared to other gyms. The super friendly atmosphere has ensured I stick with the training
Thanks for the 5 star review :)
Fantastic experience: I've been to other gyms before but K1 is by far the best of the bunch. These guys are really friendly and they genuinely care about your progress. Personal training sessions with the team are never dull and each week brings new challenges. Having someone on hand to make sure you're using correct form and push out those extra reps makes all the difference from going it alone in a normal gym. The workout area has all you need to train yourself hard. Free weights and body movement is proving to be far more beneficial than a gym full of fancy machinery. Their knowledge of exercise, functional movement and modification to avoid injuries is excellent, as it the recovery, nutrition guidance and custom online meal plan for outside the gym. The regular weigh-ins to monitor fat and muscle composition really help to keep you motivated and prove you're getting fitter, healthier and stronger. When you set your goal and have the right mindset, these guys will get you there!
Thanks for the review, making amazing progress and great to train! See you soon at K1!
Fantastic experience: I finally found somewhere to exercise where I know my injuries are cared for exceptionally well. In a PT class, there’s never more than 4 of us so, I feel like I have my own personal trainer. K1 is like nothing else. Thanks guys
Thanks for the kind words, you are a pleasure to train, see you soon :)
Fantastic experience: So impressed with these guys, very different to anything I've done before. If you are serious about making a change & fitness, maybe need some motivation in a fun environment then K1 is for you - go take the free trial :-)
Thanks Gavin, look forward to seeing you soon at K1 :)
Fantastic experience: I've been working with David Kingsbury remotely for around a year and took the opportunity to check out his new gym. Like David's personal training and plans, the level of detail and quality in the place is clear to see from first walking in. The staff are all welcoming and the showers and changing rooms are spotless. The equipment is all brand new with a boxing ring and bags a focal feature down one side of the gym. It's not a normal gym with the focus on group PT or 1:1 PT, but the classes and sessions look really good. I'd highly recommend trying this out if you struggle to remain focused with commercial gyms or can't get onto classes.
Thanks Jim, was great to see you.
Fantastic experience: Ultimate training premises, very knowledgeable friendly personal trainers, excellent facilities. Great range of exercise classes. A must Join place if your looking to transform your fitness and well being
