Fantastic experience: Thought I would try something new in 2021 and trialled the elements class. I had no knowledge of weight training prior to joining Overflow Crossfit. 1year later, absolutely one of the BEST decisions I have made on my health journey. Knowledgeable & approachable coaches, welcoming & friendly members & all round a great training atomsphere! I have learnt so much in the last year and will continue to grow in this space with the amazing support from everyone!! I feel so at home at OC especially with the friends that I now consider family! OC IS WHERE ITS AT PEOPLE - You're guaranteed to be leaving the gym at the end of the night with your cup OVERFLOWING with all the love & support! ALL HEART ON THAT FLOOR <3

Fantastic experience: I’m 14 years of age, and never pictured myself here at Overflow CrossFit, mainly because it is related to fitness. I was one of those students where PE was one of my loathed subjects . But here I am, a year and a few months later, in love with it that I never stop bragging about it to my family. The coaches and members are like a second family. They make you feel comfortable 24/7 from the day you start. The coaches constantly aid you whenever you seem lost or when technique is a bit off. Going over to the box is the highlight of my day, and will always be something I look forward to after school.

Fantastic experience: Whatever your skillset. Whatever your weight..this gym motivates, encourages and teaches you the right technique and there's no judgement. Overflow coaches and members are genuine and want to know who you are. Never an easy workout but what you gain outweighs the pain because you keep going back for more

Fantastic experience: Crossfit was something I said to myself I would never join, now look where i am LOL its now a place where I always look foward to go do the WOD & chit chat with everyone that sometimes you lose track of time going home LOL. The coaches are AMAZING + admin team. They definitely know how to assist you and it motivates you to come back the next day.

Fantastic experience: I was a bit skeptic at first on trying out Crossfit as it’s all new for me transitioning from weight training and hiit cardio, but the team here at Overflow have been so warm and welcoming almost like another family away from home. The crew have a beast list of trainers who assist you in every way to get you better at each movement or rep. Leaving all ego at the door and enjoying yourself as there’s always something new to learn every class while getting fitter and better. Keep up the great work Overflow team very proud to be apart of your awesome crossfit box community. Tala
