Our Story

Our owner, Brock Heshka, played high-level hockey in his upbringing. Himself and fellow hockey players struggled to find a place that fit their needs for sports training. Brock suffered a few injuries from poor personal training such as sciatica, back injuries and hip problems leading to hip surgery many years later. What Brock did not know is there are many different personal training certifications. He enrolled in college, studying Fitness and Health Promotion. This is where his focus shifted and he found a passion for working with the general population. Brock wanted to offer a training experience that could be held to a high standard. He wanted to combat all of the misinformation in the fitness field such as diet plans, fat loss pills, fads etc. The fear of being injured is the thought of many. Brock has been there and understands why you feel that way. It can be tough and confusing to decide who to trust. That is why Brock went the extra step to further his education to offer you more value for what you need and want.  

Training here with Brock has been amazing and I’ve seen so much progress since beginning here. Before beginning my training here I had a knee injury where I was unable to do a lot of lower body exercises and experienced pain and fatigue from standing for extended periods of time. But with the help of both Brock and the other trainers at Grit,  I’ve made a lot of progress and am now able to do any of the exercises we’ve tried and the pain has disappeared. Overall it’s been an awesome experience and I would definitely recommend!

No Machines

We focus our train around a variety of free weights like kettlebells, dumbbells, wall balls, slam balls, bands and more!  We believe there are many benefits of training with free weights over machine training.  Such benefits include; improving balance, natural range of motion, proprioception and muscular imbalances to name a few!

Sarah McGill

McGill Method Back Specialist, NASM-CPT

I am very grateful and excited to be part of the team at Grit Strength and Conditioning! I am a certified personal trainer, trained in the McGill Method specializing in helping back-pained people restore pain-free resilience and athleticism. I grew up watching desperate people live a pain-free life after working with my father and spine specialist, Stuart McGill. With my Bachelor of Commerce degree, I became the President of his company, Backfitpro, for the last three years, but my real passion was the clinical side of helping people. I knew I had to pursue this. I continue to passionately study and apply the McGill Method with my clients, empowering them to know what is causing their back pain and working to eliminate it from their life for good! Being a world-traveling digital nomad for a couple of years, it feels so good to establish a home in beautiful Muskoka and work with amazing people here.

Brock Heshka

Owner, CSEP Strength and Conditioning Coach, Pn1

Brock grew up playing a wide variety of sports but most of his time was spent playing hockey. As he moved into higher levels of hockey, off-ice training became a larger contributor to his success. It was at this time that Brock noticed a gap in access to a high quality, local, strength and conditioning facility. Brock focused on gaining experience at Fanshawe college where he studied fitness & health promotion, obtaining the gold standard in personal training certifications, CSEP-CPT. Brock loves to help people reach new physical and mental limits, and improve movement all while being mindful of limitations in current movement patterns.
