Find YOUR Zen.


Hi! I’m Hollie Krantz, the founder of Zen Gym.

I found mindfulness meditation in 2013.

Having barely survived the housing market crash and economic downturn, I then learned of my husband’s infidelity. Suffering from chronic stress, severe depression and panic attacks, I turned to mindfulness through the practices of meditation and yoga.

Quite literally, this saved my life.

Some of the most amazing souls have joined our team as instructors, each having found meditation through deep, personal journeys. What was once my “Phoenix Rising” story has become something much larger than I could have imagined.

Zen Gym

So, whether you are exploring meditation for the mental or physical health benefits, for the increased focus, creativity and awareness, or simply to develop more compassion for yourself and others, our philosophy at Zen Gym is to offer a wide range of mindfulness practices, in a comfortable, accepting space, so you can discover what resonates with YOU.

We would love you to join us. Drop in and find YOUR Zen!
