The Pandemic


In a time of uncertainty, owning a gym we weren’t sure if we would make it through the mandatory shutdown. We looked at expanding our reach in the Fitness industry as a backup plan. So we researched different products that could possibly add value to us and others in the gym space. And decided who doesn’t love chalk!

We did thorough research on gym chalk and fell in love with the idea of being in every boutique gym, climbing gym, and in the hands of other fitness enthusiasts.
