“Since working with Isaac my lifts have improved greatly and I have added around 60-70lbs to my total in just four months! This dude is so passionate about lifting AND coaching which has made him a HUGE inspiration and support system for me. Isaac handled me at my first powerlifting meet where I was able to go 9/9 thanks to his knowledge, experience, and confidence in me as an athlete. He is extremely professional and does everything with the best intentions of his lifters. I couldn't be more happy with how my training has been under his guidance and I look forward to progressing and working with him for a long time to come!”

“My experience in training with Isaac has completely shifted my lens in respect to lifting. I had just come off the back of training with another coach and my experience with them made me believe I wasn’t cut out for lifting. However, one I started with Isaac he was so patient with me and made me feel like I was valued and had a future in the sport of powerlifting. His passion and energy are unmatched and are ultimately contagious. To put it neatly, I won’t be leaving team Whistler for a very long time.”

“Isaac is a great coach, he’s not one of those guys that gives you a program and wishes you the best. He helps you to his best ability, whether it’s form or nutrition!! Personally going with Isaac as my coach has been one of the best decisions I’ve made in powerlifting so far! He enjoys seeing you progress and when you hit a PR, he hypes you up like it was a world record! On top of his coaching abilities, he’s a heck of a guy! You can tell he enjoys coaching just by the sheer energy you gives off of everything he does!!”

“Isaac Whistler is by far one of the closest friends I’ve had in a long long time. I’ve only been working with him for a span of 4 months and it’s crazy how close I’ve come to him and the rest of the FLEXX squad. I come from a body building back ground and decided to get into strength training in December of 2020. I then reached out to Joey and applied on the FLEXX website and the rest is history. I started off with a 405 squat, 315 bench and a 405 deadlift. I am now 3 weeks out from my first meet and my numbers have sky rocketed. As of May 2021 I know have a 405 bench, 580+ squat and 560+ deadlift at 93kg. Being a part of the FLEXX squad is truly an experience. It’s more than a team but it’s a family. Isaac’s ability to communicate with his athletes is truly inspiring. With any questions or concerns I have for him he gets back to me instantly and his dedication is absolutely insane. He truly cares about all his athletes and will always be there no matter what. His knowledge within the powerlifting realm is also insane. He’s helped me get through any setbacks and plateaus. Not only that but he truly connects with all his athletes regardless what your situation is. Isaac thank you for everything and Im looking forward to the future brotha. Let’s continue to make a lot of gains. Love you brotha.”

“Isaac is the most humble and genuine guy I’ve ever had the pleasure of meeting. Aside from working long hours and training for his own goals; Isaac has never let me down when it comes to responsiveness and always having a positive attitude. Adding over 100lbs to my total in a matter of 8-10 week, Isaac is serious about getting you the results you need.”
