Google review from Jandre Brits

This place has the best people to get you motivated and help you get fitter and stronger. When i went to gym on my own i did not see results after just 2 months here everyday i see more and more of a difference.

Google review from Tasneem Dawood

I really struggled with exercise after having a c-section, I was ready to give up but Stephen took the time to help me with recovery, I am so grateful for this. Joining Core one was the best decision, I feel stronger and healthier. The trainers are just awesome and so friendly, they're always willing to provide extra support to help me reach my goals. Definitely a great place to be!
