What People Have To Say

Absolutely amazing training!

I’ve been training on my own for a couple years and came to Brock to get the extra push, and push is what he has done! Taught me new moves and corrected my form and explained the reasoning behind everything. He has brought the spark back into my training!

Amanda Edwards

I began training with Brock after recovering from a serious concussion. I didn’t know who to turn to after gaining several pounds and not feeling confident in my body. Brock welcomed me with open arms and presented me with a plan I thought was achievable and realistic. He encouraged me, pushed me and taught me so many tips and tricks I will continue to use. Brock is extremely knowledgeable both in the gym and when it comes to healthy eating and recovery. Brock is personable, professional and runs a great business that will continue to grow and expand in Muskoka.

Jared Stevens

I started training with Brock three months ago and have never felt better! His knowledge goes beyond what should be expected of a personal trainer. When I first started, we had a few hurdles to overcome with my form – he quickly corrected where I was going wrong resulting in pain-free exercising! I have seen amazing physical results since starting with Brock, but more importantly, I have seen a boost in my confidence. I look forward to every session and challenge he brings my way!”

Amanda Sherif

I have thoroughly enjoyed training at Grit Strength & Conditioning. Brock is a fantastic trainer and coach. He is super knowledgeable and very professional. He knows how to help you achieve your goals in the most effective way possible, with very personalized workout plans. The workout plans really help to focus in on what you are looking to achieve, whether it is weightless, toning or just to keep active and stay fit. I would highly recommend Brock, and his gym to anyone looking for a fresh start, to stay fit and active or just to just get a good sweat on. In my opinion, this gym is great for anyone, no matter what your experience level is!! I look forward to continuing to train with Brock in his gym.”

Jean-Michel Barrette

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!

Listen up! If you are looking for a personal trainer who is knowledgeable, dedicated and professional, Brock Heshka is your guy. I have been working with Brock for 7 months now and I can honestly say that he has changed the way I think about my health. There is so much misinformation out there – especially geared towards us 50ish year-old females! Brock is patient. He does his research and is able to chunk our workouts into manageable sessions. I cannot believe how strong I am becoming! He often sends articles and information based on the things that come up during our sessions. Ladies – don’t let his age fool you – Brock is the most knowledgeable trainer that I have worked with. He is also connected to other like-minded health care professionals. If you are looking for a holistic approach for a healthier you, then look no more. Give Brock a call!

Since I began starting to train with Brock, I have already noticed myself getting stronger and feeling better and it has only been a month! It’s also a great location because it is only ever you and the trainer. There are no distractions by other people in the gym and you can really focus on yourself. Loving it and would recommend to everyone!

Emily Scott

Being teammates with Brock this past year it was a no-brainer I would give his program a try, especially after seeing his dedication to fitness and the knowledge he has to go with that. Brock wrote me a program to get me ready for my USHL try out, where his program made me stronger and faster leading me to a great camp. Would recommend to anyone looking to improve their athletic ability or anyone just looking to become more fit and healthy.

Hugh Anderson

Brock Heshka is an amazing trainer. He is more knowledgeable and qualified than any other personal fitness coach I have ever met. His drive allows him to put 110% of his focus into creating a program that meets my individual goals and needs. His concentration on injury prevention is inspiring, as he does not push me beyond my physical limits. The mental and physical strength that he promotes, gives me confidence that I will reach my goals with his guidance. I would highly recommend him to anyone who is interested in one-on-one training that will help boost all health aspects of their life. I look forward to many future sessions.
