Fantastic experience: I requested an ad-hoc session for my mum out of the usual hours. Emma straight away offered to take the session and was absolutely fantastic. She catered the session perfectly for both my parents and was extra generous with her time and sharing her expertise. Thank you Emma!

Fantastic experience: I dropped in today for the CrossFit Open, as I was passing through, and Jack couldn’t have been more welcoming. His team, athletes, box and facilities are awesome. Other CrossFit boxes in St.Albans and Harpenden don’t do drop ins but there was no issues at Six Hills. Totally recommend this place! Thanks Jack

Fantastic experience: Fantastic coaching, equipment, and community

Irene Ulman 2 years ago

Fantastic experience: Great coaches, brilliant atmosphere and I have not seen anywhere else like it. Love being here and have learnt a lot and will keep learning and improving. One of the best things you can ever try! Beauty of crossfit is that it can be scaled so it is for beginners as much as it is for someone who has done crossfit for years.

Corinna C 3 years ago

Fantastic experience: After doing CrossFit for a while in london I was nervous about relocating and finding a new box, especially as I was pregnant. However Jack and the Six Hills squad welcomed me with open arms and made me feel so welcome! Jacks knowledge and coaching for me as a pregnant woman was incredible and I didn’t once feel like I wasn’t able to train or was a burden. Since having my baby, I was able to ease back into exercise and able to bring my baby to the box, which has been a life saver otherwise I would rarely get to train. The Six Hills community is so friendly and motivating and I’m so glad I found them!

Fantastic experience: I’ve been a member of this CrossFit box for almost 4 years now and I absolutely love it! Such a friendly, all inclusive place to work out! The coaches are so knowledgable and I can’t imagine getting my fitness fix anywhere else. I’d highly recommend this place to anyone looking to improve their fitness/mobility whilst making some new friends along the way!

Fantastic experience: Great box with a fun, supportive and inclusive atmosphere. Coaches are also easy to get on with and very helpful for beginners such as myself. I’d also like to point out that I’m the Six Hills CrossFit 1 mile run record holder so I know my stuff ;)

Fantastic experience: Incredible gym squad, Incredible coaches and Incredible owners. Everyone welcome, the quality coaching and programming is super high making for an amazing fitness experience for all levels. I’ve been going to gyms on and off for years, but always struggled to really be consistent or motivate myself. That was until I found this gym and CrossFit. Now I’ve created a really consistent routine, that I actively look forward to working out everyday. It’s changed a lot in terms of my confidence and has re sparked my competitive nature which has made it all the more enjoyable. Fully recommend if your thinking about trying out CrossFit!

Wayne Gammon 6 years ago

Positive experience: Not as big as I thought it was going to be, a pricy but then that might be because I am a northerner.

Fredrik 6 years ago

Fantastic experience: Dropped in on a visit while on work in Stevenage. Emailed about joining a class and got a swift reply. Location is easy to find and I felt very welcomed! Fun class and great WOD. The box is quite small but feels very roomy! Equipment is in good condition and the price was very fair! Love to come back!

phil newman 7 years ago

Fantastic experience: Great place to be pushed out of your comfort zone. I do a lot of one off sessions here. (Would sign up fully if I didn't work so late!) A lot of people are unsure as to give CrossFit a try, but as a personal trainer myself I can safely say that Holly, Jack and the other coaches here teach great technique/form. Super hard workouts that leave you feeling great after!
