Frequently Asked Questions
Can we run HYROX sessions in our current facility - isn’t it the same as functional training?
Can we run HYROX sessions in our current facility - isn’t it the same as functional training?
HYROX needs clear movement lanes, specialised stations and enough space to keep athletes moving without congestion. Most designs will create safety risks, but, we design the space specifically with HYROX in mind. So, classes run smoothly and feel professional.
Do you need specialist flooring for HYROX?
Do you need specialist flooring for HYROX?
Regular turf wears out fast under sleds and heavy conditioning work. It becomes slower and inconsistent over time, posing safety risks. We install turf designed with this in mind so you get reliable resistance, longer lifespan and a better overall experience for your members.
How do we compensate for busy classes?
How do we compensate for busy classes?
We design with flow in mind. This means that we ensure there is the correct spacing, duplicate stations (where needed) and smooth transitions between movements. It keeps classes organised, reduces waiting time and improves your sessions.
Will a HYROX area make the gym look cluttered?
Will a HYROX area make the gym look cluttered?
No chance. With years of experience in facility design, we can combine performance with clean, branded finishes and integrated storage. Your facility will look premium, designed and aligned with your identity while meeting HYROX standards.
