“Hi everyone, my name is Warren Leslie and I am the Head Coach of our Athletics Program as well as a Trainer here at World Gym Plus 15! I struggled for years to find direction in the gym and could never quite get the results I was hoping for. Once I invested in my own fitness by hiring a Coach, my workouts started to become exciting and the results became very rewarding! I want to have the same positive impact on my client's lives, while providing customized programs that will get you results both mentally and physically. I love showing people that living a healthy lifestyle doesn’t have to be a chore but something you look forward too everyday! I’ve worked with a wide range of people over my career, from athletes to beginners. No two clients have been the same and neither should be their fitness programs.

About Our Team



Trained By Warren

I’ve been a member at World Gym Plus 15 for almost a year now. The entire team at World Gym are friendly and accommodating. I’ve been training with Warren since I started at World Gym (with a break for Covid). The excellent results I’ve achieved are due to Warren’s training techniques. He challenges me, all while paying close attention to, and working with my limitations. Warren’s professionalism, positive attitude and extensive knowledge keeps me motivated and helps me push my limits, and achieve my fitness goals.


Trained By Ross

Working out with Ross has given me the confidence in the gym to go after my goals and push myself further than I thought possible. I have learned proper lifting technique, new exercises, and an overall approach to working out. Ross keeps me motivated and on track. I have enjoyed playing sports again (pain free!) as I gain flexibility and strength.


Trained By Ross

Ross is one of the best Personal Trainers in Calgary with exceptional programming customized to achieve your goals. With Ross’s programming I am lean, strong and exchanging bad habits for good. Ross has transformed my squat! Proper technique and form is the name of his game. Ross is very knowledgeable and does a killer job to break down each movement, ensuring safe and effective movements.


Trained By Jairo

The day I met Jairo, I was going to quit the gym. I was unmotivated, too shy to workout and in a lot of pain. For the past forty years I had forgotten about myself. I had neglected my health and kept putting on weight, each year I felt worse than the last. Jairo promised me on that day, that if I could give him 36 sessions, only 36 hours, then I would see a big change. So I decided to stop forgetting about myself and put my effort into my goals and dreams. Now less than a year later I am almost 30lbs lighter, I can lift 200lbs and I look and feel like a completely different person. Jairo has truly changed my life. I am happy! So so so happy! I go to the gym 5-6 times a week, I am encouraging others to start living a healthier lifestyle and all of this would not have happened had it not been for Jairo. He has supported me through everything and continues to encourage me to set and achieve new goals. Thank you, thank you, thank you, Jairo!
