This is without a doubt the gym to join, I can feel and see a difference and I am motivated for the first time in 10+ years to workout. CoreOne has made all the difference in my life and I remain a big fan.

Impeccable gym, functional and involved trainers, a personalized approach to fitness, by all means not conventional, the workouts are tailor made to suit your needs, give it a try... so excited to be part of this journey...

I've discovered a new type of happiness – the kind that comes with dumbbells and burpee triumphs! My daily routine now involves more reps than regrets, and the only thing heavier than the weights is the load of fun within the 8am class.
