Ternion Fitness & Athletics
Supplemental Performance Support for Competitive Athletes
We work with athletes already competing at a high level—supporting their development outside of team practices so they can train, compete, and progress year over year.
Not a general fitness facility. Not a shortcut. A long-term performance environment.
Who We Work With
Ternion supports rostered athletes competing at the provincial and national level across team and individual sports.
Our athletes are already committed to their sport and organization.
Our role is to enhance physical preparation without interfering with sport-specific training.
If your athlete is:
They may be a good fit.
Our Role
We don’t replace team training.
We build around it.
At Ternion, physical preparation is planned in coordination with:
Our priority is simple:
progress without compromising availability.
How We’re Different
Many athlete programs focus on intensity, volume, or short-term gains.
We focus on:
We believe the best performance support is often the least visible—but most reliable.













We started at Ternion about a month back and this has by far been the best decision we have ever made for our personal growth and fitness. Training with Sly has been a game changer for both me and my husband. We have challenged our body physically in every session with the dynamic training but more than that, it has also worked on developing a more resilient and positive mindset for both of us. Sly doesn’t just train you to become the best consistent version of your physical self, but also changes your outlook towards nutrition and self care. At Ternion, you enter an environment of positively charged and encouraging group of people. Nothing seems forced and you always feel motivated to give your 100 percent when you are there. If you are looking for a machine pumping gym setup, this is NOT the place for you. But if you want to push your body and mind to the limits of your maximum potential, then you have come to the right place. We highly recommend Ternion and their entire team, specially Sly, to anyone wanting to excel in their lives.
Through all my years of working with various trainers, as an athlete I can assure you Ternion is top tier. Their devotion to everyone makes the aura feel as if we’re family. They absolutely want to see you succeeding and will guide you to being the best version of yourself. Truthfully I am thankful for the bonds I’ve made and all the lessons I continue to learn in and outside of the gym! I’ve never been one to consider mindfulness but now that I have there’s no going back. I’m grateful for the new perspective on life and it has really changed the way I approach obstacles. A forever reminder is to “be the person you want to be”-Shamar Wright. I’ve made the change and will continue my journey with Ternion Fitness, I hope you will too!

Sly has helped my son develop both mentally and physically and he is now very motivated and hungry for success!! I highly recommend MR. Sly . Keep growing brother !!!! Good Luck !!
I have been working out at Ternion for just over half a year now, and not once have I ever dreaded coming. The staff are super friendly and encouraging, the workouts do not only stress your body but also your mind. I would and have already recommended Ternion to anybody who wishes to push themselves to becoming the best physical and mental person they can be.
I would definitely choose Ternion Fitness & Athletics again. Excellent facilities in Mississauga and the Trainer (Sly) was very professional and welcoming. I had a lot of questions and he took his time to explain the program to me. His famous words are “Trust the Process” and I definitely do, as I do see the improvements with my daughter. All athletes are welcome, as well the average person that just wants to get moving. Check it out, you won’t regret it!!!!
