The Youth Development Program was created by Coach Kyle –  Strength Coach, Lacrosse Performance Specialist, and founder of Relentless Lacrosse. 

Originally working with elite hockey players, Kyle earned a reputation for the training that actually translated to the game and quickly became sought after by local lacrosse pro and NCAA players. 

Combining intensive academic education and thousands of hours working hands on lacrosse players in the gym – Kyle has also worked on-field with elite skills coaches to break down the movement mechanics that can be refined and optimized through Relentless programs.

Kyle has become a go-to authority on performance optimization for lacrosse players and continues to evolve Relentless programs to ensure players have access to the best possible resources to elevate their game.

Dylan had all the skills on ice to play AAA but just kept getting passed up for not being “strong enough” to play at the higher level. Using the Relentless Hockey program he put on 14lbs of muscle!! He’s playing more confident and not shying away from getting physical out there – training with Relentless Hockey has completely changed his game!He’s pumped for tryouts and can’t thank you guys enough!!

I found Relentless Hockey on Instagram & as a physiotherapist LOVED so many of your post and the approach to hockey training. When I saw the youth program I had to get it for my guy.. and the result have been awesome! He's added muscle, his stride looks great, and he's playing strong and confident (even getting called up an age!) We love Relentless Hockey!!

This is exactly what Trev needed! He was in the gym with his team once a week - but knew he had to get stronger & wanted to get into the gym. Having him use such a high-quality program was huge!

His core strength is off the charts and other parents keep asking what he's doing off ice.. because it shows!

Seems expensive, what should I invest in this vs just doing my own workouts?

Many players can train on their own, but the truth is that random training creates random results. Success demands structure. 

Relentless Lacrosse was built to take the guesswork out of Lacrosse player’s training and give them the exact structure that’s been refined by thousands of players to be proven to translate to the field. 

Working with a Strength Coach that understands the specific needs of Lacrosse players can cost upwards of $120 dollars per session or joining a 12 week group training program can easily cost over $2000.

With Relentless Lacrosse, you have access to the exact workouts that pros are paying thousands of dollars for.

What ages and level of youth lacrosse player is this for?

We recommend this program for ages 13-15.

This program may be appropriate for younger players if they have experience training OR are doing with their workouts with a parent.

We'll often have parents buy this program for their player to do during family workouts at home or when they bring them to the gym.

What kind of exercises are included?

Admittedly, a lot of these exercises will be new for a lot of athletes.

This isn’t just a classic bodybuilding style workout where you’ll see 3 sets of squats and lunges. Relentless programs are loaded with integrative exercises that challenge you with unconventional movements. 

You’ll have a Youtube Playlist with demonstrations of each exercise in that days workout so that you’ll always know exactly what to do.
