    I have had the pleasure of been trained by grungefitness. I was extremely obese and hated the gym or anything the required me breaking a sweat. He made me understand the importance of been physically fit and literally held my hand through the process. I have not looked back ever since. Easily the best decision I have ever made, putting my health first. In summary, he is the best trainer in the GTA, Period. 😊

    Coach Grunge is the best, NO CAP. Getting the right trainer used to be so draining but thankfully i got mine now lol. He knows his stuff and i am proof of that. I started my fitness journey with him when i was 205.2lbs (L, XL) and with his help, direction and motivation i was able to reach and beat my goal weight which was 150lbs (S). Now that my goals have changed, i am so excited to work with him to get those gains in!

    I have had the pleasure of training with Coach Grunge and It was an amazing experience. Throughout the session he made sure our posture and execution of each rep was proper. He is very knowledgable and knows how to motivate and empower anyone who needs guidance. He is not scared of pushing you out of your comfort zone and keep you accountable. I definitely recommend him if you are serious about making a change.

    Collins Grunge is a very capable fitness instructor who understands each individuals specific fitness goals and customizes fitness programs to meet their objectives. I have found him to be focussed on the job and gives constructive advice to improve ones fitness levels.

    Collins is one of my favorite trainers in the world! He is very safety-oriented and a specialist at correcting back pain issues through exercise. Having that specialty takes a lot of knowledge, experience, and practice. That’s why I always recommend Collins; especially when clients need corrective exercise for their posture or to resolve back pain
