What People have to Say

"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!"


"Brock is extremely intelligent and is very experienced when it comes to sport specific training. He is a great asset for off season training or if you are interested in improving your overall fitness."


"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!"

The Grit Advantage

Wtih 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.

Athletic Performance Development


Are you looking to move on to the next level? Do you want to gain an edge over teammates and opponents so that scouts will notice you?

At G.S.C we specialize in athletic performance.  Founder, Brock Heshka was in the same situation as you before he followed his passion for fitness and helping others achieve success. Heshka played competitive sports at a high level for 10 years so he has the experience and knows what it takes to use fitness to take your game to the next level.

Athletes that join our program will be assessed and receive a specific program based on their fitness and athletic goals. This specific and custom program will be tailored to reflect what is needed to excel in your sport. Since not all athletes are the same it is important that you receive a program specifically for you. We offer a 5 phase program for a variety of athletes in the off-season.

Maintaining a high level of athleticism throughout the season is just important as building said athleticism in the off-season. Since speed, power out and strength has the potential to diminish readily through the season without adequate training, we offer in-season programming for our athletes that move away during the season.

Join our Athlete Program and make your next season your best one yet!

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.
