CoreOne Gym Mulbarton Johannesburg South

We've been helping people grow from strength to strength since 2011.


Why gym with us?

Personal training in small groups :)

More affordable

The personal trainer costs are shared by the group, so you still get guidance and support you would get in a one-on-one without burning a hole in your pocket.

Small groups

Gymming in a group is way more fun and motivating. Plus, you still get indivudal attention, feedback, and help with your form from our personal trainers at CoreOne.
