our story
CrossFit PTBO was born July 2015 – our doors officially opened end of August 2015. They had a vision of what they wanted in a CrossFit gym and there was nothing like it in town. They took the leap and decided to open up CrossFit PTBO.
Their first location was 638 The Kingsway and it was just over 4000 sqft of space. They made it their own space but they always knew this wasn’t going to be their home. Dave began working full-time at the gym as of January 2016 and by a stroke of luck, around May 2016, they found their second location, 680 The Queensway (over 6000 sqft). All the stars lined up and they moved into their new location July 2016. Fast forward to May 2020, CrossFit PTBO moved to 701 The Queensway and it has instantly become our home.
They have been evolving since then by building up their personal training portfolio, growing the Weightlifting Club, expanding in group CrossFit classes, and specialty programs. They are constantly trying to reinvest into the business.
Ruth and Dave are committed to their staff and members, and are driven to providing the best services to help people achieve their health and fitness goals.
