The Grit Advantage

With each of our clients, we take an individual approach rather than a one size fits all.  For each client, it does not matter if they have never stepped foot in a gym to a seasoned athlete, workouts and programs will be tailored for their current fitness level and goals to maximize results. With personal training being an unregulated profession 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.

Our History

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 offer experience that could be held to a high standard. There is also a lot of miss information in the fitness field such as diet plans, fat loss pills, fads etc. Also, 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 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.


What People Are Saying About Grit
  • I sought out a personal trainer after a back injury left me unable to get back into shape on my own without causing re-injury. I Googled, “Personal Trainer”, and luckily, I came across Grit Strength & Conditioning and Brock Heshka. I chose Brock because of his knowledge of, not only, health & fitness, but specifically his knowledge of how to strengthen and rehabilitate injuries.

    I have not been disappointed with my choice for one second!! Brock and his team are excellent at what they do! I have been working out with Brock for almost a year and the growth I’ve had, the strength I’ve built and the confidence that comes with it, could not have been done without his help! I am still not without setbacks but with Brock’s patience, he simply adjusts the exercises we do and we keep on moving forward. His individualized plans are effective, challenging and NEVER boring! Thanks, Brock, for giving me my life back!!

  • Brock’s expertise has been integral to my health and healing journey. A year and a half ago, I was in a car accident which left me in pain and fearful to do the things I did before the accident. I found Brock’s website, emailed him and that was 6 months ago. I was never one to prioritize exercise, I am in my late 40’s and was not thrilled to join a gym but I knew I had to do something.

    I am SO GLAD I did! Brock has been a real blessing and he and his staff are non-judgmental, fun to be around and above all – professional and truly skilled trainers. The people he attracts as customers also reflect the warm and inviting atmosphere that Brock has nurtured in his gym.

    I can sleep now, I am not afraid to do domestic chores, I feel confident and strong. I lost inches and gained muscle. I am very grateful to Brock and I recommend that anyone out there who is at the point where they think that this is as good as it gets… check again! Brock will design a plan for you that is truly unique and tailored to your needs. He has done more for me then any physiotherapist has and I owe him my sincerest THANKS! Emailing Brock was the best thing I could have done to help myself and my family. Thank you, Brock! You truly are a life-saver!

  • I have been training with Brock and his incredible team for just a little over a year now. My mom had originally been training there beforehand and introduced me. Since then, I’ve never looked back.
    I think it’s safe to say Brock and his team are hands down the most experienced and committed trainers around in Muskoka. They have so much passion and knowledge for all things regarding fitness and health and they’ve truly transformed my life! Brock designs a program specific to each client’s goals and makes what once may have seemed impossible to possible. No matter where your fitness level stands, Brock and his team are dedicated to helping you attain your goals! They’ve shown me just what my body’s capabilities are, and I’ve never felt stronger and healthier. I’m doing things now that I’d never even DREAM of doing before! If you’re looking for a trainer who not only motivates you but also can provide you with proper techniques to maximize your performance, Brock and his team are where it’s at! 100% recommend!!
