GRIT was originally created from a gap in the Muskoka fitness market our owner, Brock Heshka, had noticed. There was no place for higher caliber athletes to get the proper training they required which lead them to drive an hour or more for adequate coaching.

This is how GRIT was formed – to meet the needs of local athletes looking to improve their athleticism and gain a competitive advantage over their peers. Our clientele based shifted and the demand for our service from general population clients jumped exponentially throughout the first few years of operation. 

Further making our mark on the fitness community in Muskoka we launched our brand new 6800 sqft state-of-the-art facility in late 2021 offering a truly unique training, yoga, fitness and health experience for Muskoka to enjoy and thrive.

Lets Get Started

We are driven to be the spot for your fitness and yoga needs. We have a variety of memberships, class pass options, class styles, and different levels of training to make sure you are adequately serviced.

Our Mission

Our mission is to provide an unmatched training experience through our state-of-the-art facility, amenities, and services we provide. Our coaches focus is to take our clients from where they currently are to safely and effectively help them attain their goals.​

Our Philosophy

Everyone who walks into the gym is different.  We take an in-depth approach when creating tailored programs to accommodate everyone’s specific needs.  Our facility is designed with a premier mindset and to give our clients the tools to have their best training experience second to none.



With each of our clients, we take an individual approach rather than a one size fits all. Workouts will be tailored for their current fitness level, training & medical history and goals to maximize results.

Personal training is an unregulated profession meaning anyone can call themselves a personal trainer. That is why at GRIT our trainers bring qualified post-secondary schooling in the fitness & health field and extensive practical experience to our facility. So you can feel confident in your choice of joining GRIT.
