Relentless founder & director of performance

A Personal Note:

Hey There, my name's Kyle & I'm the founder of Relentless.

I'm amped up that you're checking out Relentless Lacrosse & trying learn what we're all about.

Chances are, I was just like you.

Back when I was athlete and chasing my hockey dreams, I used to scour the internet looking for what I could be doing to take my training to next the level. I genuinely attribute my success as an athlete to Strength & Conditioning and t the relentless pursuit of getting better.

Now I do this for a living and help the next generation of athletes.

Starting off with hockey, I worked with thousands of the best players from around the world. Relentless Hockey quickly gained popularity, and I had the fortune to work with players not only from around the world (25+ countries) but also at the highest level of the game, from European Pros to the NHL/KHL.

Being in Canada, it wasn't long before I had lacrosse players reaching out to train too - and I had the fortune to work with hundreds of lacrosse players from youth lacrosse to the NLL/PLL.

Now, I get to distill these thousands of hours working hands on with lacrosse players into Relentless Lacrosse. We've create the exact resources and training programs that I know make a difference for lacrosse players.

Relentless was built for athletes like you. So if you ever have any questions, or want to connect, or we can help you with you lacrosse goals - please don't hesitate to reach out!

kyle kokotailo: hockey trainer


Kyle is a former elite athlete turned sought-after Performance Coach.

As a former hockey player, he played Junior A across Canada before returning home to captain the Burlington Cougars. After Junior, he was recruited to the University of Toronto, where he earned his Bachelor of Kinesiology.

After playing, Kyle shifted his focus to athlete development - working as Strength & Performance Coach for elite hockey players. Earning a reputation for getting results that actually translated to sport, Lacrosse Players started to reach out to join workouts.

Eventually working with dozens of NCAA and Pro players, he committed to learning the mechanics of lacrosse, not only studying film with players, but working with local Lacrosse Coaches and attending skill sessions to help breakdown the movement mechanics of everything from foot workout to power expression.

Kyle's work with Lacrosse Players and the commitment to on-field results started getting noticed his players teammates from across North America who started to ask for digital programs. This led to the creation of Relentless Lacrosse and the shift to delivering the digital programs and resources that get lacrosse players to the next level.
