CrossFit® Vastus: Opinions
Fantastic experience: Great and friendly atmosphere. Hard training that pushes you to improve. Best gym I’ve been to!
Thank you so much Tom. We're really glad you're loving it — it's awesome to have you as part of the team. Keep up the great work, and we’ll keep pushing together!
Fantastic experience: I dropped in for Saturday, partner workout that was a great challenge and beautifully scalable for everyone. It was immediately evident that the community has found a safe and inviting place in CrossFit Vastus. In addition to the warm and immediate welcome I received from Ruth and David, it was obvious that the regular members really enjoyed being at Vastus. It took no time at all for that comfort to be extended to me. I think that just as valuable as Vastus’s immaculate new space, ample equipment, and challenging programming is their community spirit. CrossFit Vastus has a strong and friendly community. It was a great place to visit and I recommend it to anyone in the area.
Ryan, it was great that you were able to spare some time in your travel plans to come and drop in. We always love welcoming new faces!
We are so pleased to hear you enjoyed your time with us. Thank you for your kind words and recommendation. We will look forward to training with you again, when you're back in the area!
Fantastic experience: What a great place and people to be around! Been going for more or less a year and just love it! 1. So nice to see so many different age groups and levels in every class and never feeling out of place regardless of your skill level 2. Great training so many different skills, sometimes you have fun cause you’re doing the thing you’re good at, other times you feel good cause you’re mastering something you never thought you could 3. Dave and Ruth are GREAT, they are so cautious about you only doing what is good for you and not hurting yourself while pushing you when they know you can do it, but also understanding when you are needing an easy day (as a chiropractor I appreciate the skill coaches must have to make sure one takes care of their body). Not to mention how kind they are and how they make you feel so at ease all the time! 4. Everyone in that gym is great
Sarah, Thank you so much for your lovely words. We are so pleased that you enjoy your time at Vastus. We love having you as part of the team!
Fantastic experience: Crossfit Vastus embodies everything a Crossfit gym should be. From the moment you walk through the door you aren't a new person, you are a member of a family and community of people striving to help and support each other. It is all inclusive and has something for everyone. David and Ruth are amazing coaches whose dedication and commitment to their clients is second to none. I honestly cannot say enough good things about it.
Mel, thank you for your lovely words. We love having you train with us and are so glad that you are getting so much out of it!
Fantastic experience: The best crossfit gym! David and Ruth make you feel welcome and help you with all movements so you can progress further.
Thank you Anastasya, we are really glad you are enjoying it. It is a pleasure to have you come along!
Fantastic experience: Having been actively involved in rugby and fitness for decades I was at a loss when I retired from rugby. Then I found CrossFit Vastus. The range/ type of exercises have helped massively with both fitness as well as getting rid of aches and strains over the years due to the functionaI elements and great coaching! Most significant has been the community that you become part of. No egos and everyone is suppportive of all abilities, driving each other on. Having recently visited a main stream health club (no names but the linked to Tennis), it just lacked the atmosphere and camaraderie that you get with CrossFit. No going back!! Absolutely love it!!!
These are kind words, thank you. We love having you train with us and are super glad you do!
Fantastic experience: I’ve been going here for 18 months and it has definitely helped my strength and flexibility. David and Ruth always adjust the sessions and make every session challenging but achievable. I just love it and the community spirit and the way everyone welcomes you. I’m in my late 50’s and was nervous about joining but it’s honestly the best money I’ve ever spent.
We're so glad you are loving it. We love having you train with us!
Fantastic experience: CrossFit Vastus is a not just a gym but a real community of like minded people who are not only supportive but can have a laugh whilst getting sweaty. I love going and David and Ruth are amazing.
Thank you Naz. We love having a giggle with you, we are so glad you enjoy coming along!
Fantastic experience: David and Ruth have created more than just a gym and place to do CrossFit. An inclusive, engaging and fun place, which challenges you to improve and better yourself with no egos and accessible for all.
Thank you David. We love having you train with us!
Fantastic experience: I joined Vastus back in August 2022 and haven't looked back. David and Ruth are so helpful and made me feel at ease from day one. Cannot recommend Vastus highly enough!
Thank you John. We love that you feel comfortable and at ease training with us!
Fantastic experience: This is truly a great place. Ruth and David are amazing. If you are looking for crossfit training, this is the place for you
We love having you train with us. Glad you are loving it!
Fantastic experience: Brilliant gym, great coaches and excellent community. Strongly recommend
Aw thank you Matt!
Fantastic experience: Lovely new box friendly and good quality equipment 10/10
Thanks so much. Was great to have you come and join us today for Open Gym. Hopefully see you again soon.
Fantastic experience: I had the pleasure of visiting CrossFit vastus several times while visiting family locally. David and Ruth were really welcoming and so were all the members I met! The box is really well kitted out and the coaching was excellent! Workouts were tailored to all levels/fitness experience. I have been lucky enough to visit various CrossFit locations while at home in the USA (or while traveling) and this was right up there with the best! Would definitely recommend if you’re looking for a friendly, encouraging and fun place to workout.
Bev, thank you so much for your lovely words and review. We are so pleased to hear you enjoyed your sessions training at Vastus. It was great to have you with us. We look forward to having you drop in again when you're back in Buckingham!
Fantastic experience: I'd never tried Cross fit before and was quite intimidated by it, but David, Ruth and the whole Vastus community made me feel so welcome and I felt at home there in no time. Everyday is different meaning you're never bored. Vastus is such a warm and welcoming environment suitable for all fitness levels. A great place for your mind, body and soul! Highly recommend.
We totally understand that it can be intimidating starting CrossFit, but we're so glad that once you walked through our door you felt at home! Thank you for being part of our team!
Fantastic experience: CrossFit Vastus is a fantastic gym and has created a community of lovely welcoming people. I’ve always enjoyed exercise but I’ve finally found a gym that pushes me every session and is enjoyable! As someone with joint issues there’s always an option to scale the workouts and the coaches David and Ruth are so considerate, it’s very inclusive. Highly recommend Vastus!
We are so glad you enjoy coming along. We loving having you train with us!
Fantastic experience: Been a member for about a year and a half. I was a bit apprehensive about joining a CrossFit gym in my late 30s (been going to commercial gyms for all of my adult life) but it’s the best thing I’ve done. David keeps the sessions interesting and both him and Ruth push everyone to do their best but in a safe way. To say joining Vastus has been a life changer is an understatement. I’ve made some great friends and consider myself a proper ‘CrossFit Wan@er’ now. Looking forward to seeing how Vastus develops over the next few years.
Wow, thank you for your brilliant review! We love having you as part of the team!
Fantastic experience: Vastus is an incredible place which has built an excellent community since opening. Vastus brings so much more to Buckingham than just a gym. Since joining I have become part of a strong friendly community. Our coaches David and Ruth put everything into the sessions to ensure we continue to grow and develop in our fitness and goals. Vastus is suitable for all abilities and once you join you won’t look back. I look forward to seeing what is next for CrossFit vastus!
Hannah, that is super kind of you. We love having you train with us!
Fantastic experience: CrossFit Vastus is exceptional. They've destroyed any preconceptions I had about CrossFit and the stereotypical CrossFit goer. This gym is amazing and the coaches there are really knowledgeable and are able to tailor the workouts the anyone's personal ability levels. The workouts are varied and well put together and will improve your skill and coordination as well as your cardio and strength. I couldn't recommend them enough.
Thank you so much for your recommendation! We love having you train with us and we're glad to hear we have changed your view of what a 'CrossFitter' is!
Fantastic experience: Vastus is much more than CrossFit. It is a community with very welcoming coaches and members. The training programs are great and I really feel I am getting better every week. Whatever is your goal, I highly recommend it. As I was relocating, I also got really good tips on pretty much everything I needed to thrive in Buckingham
Thank you Érico. It's been great having you train with us. And we were/are more than happy to help with all your relocation questions!
Fantastic experience: Crossfit Vastus is truly incredible. The coaches David and Ruth provide excellent direct coaching in small group settings, so that we are always being pushed to achieve and learn more, and always in a hugely enjoyable way. Don't worry if you have never tried Crossfit or don't know what it is - if you like any form of exercise you will love it and be welcomed into the group to try it out.
Thank you Jo. We're so glad you feel that way. It's great having you as part of the team!
