pour rocket fuel on your player's development

Youth lacrosse is more competitive than ever.

These days every young ambitious lacrosse player is putting in extra work on the field,  the real secret to accelerating lacrosse development away from the field. with strength & conditioning.

With the right strength & conditioning, players are building the foundational strength, power, and conditioning, sets them up for success long-term,  while giving them an dominant edge this season.

Elite lacrosse players are built off the field - and it starts now.

Now's the time to accelerate player development.

I gotta take it up a notch this year Dad…”

Last season Noah had been one of the last cut from one of the best youth teams in the state.

The truth was, he was a good lacrosse player – but his dad knew he wasn't ready to play elite lacrosse.

He had strong stick skills and a good vision for the game, but he was missing that strength and explosiveness that the dominant players his age all had.

But heading into this year's tryouts felt different. The last few month he had become obsessed with becoming a better lacrosse player. Daily wall ball, creating drills in the backyard to work on his dodges, ripping thousands of shots at a now tattered net, even going for runs and doing workouts at home

“Noah, you looked great out there buddy... Your game has come a long way, but we just don’t have a spot for you this year."

It was the conversation that all parents and athletes dread – he got cut. 

A couple days later, one of the assistant Coaches, who had played lacrosse with Noah's Dad, reached out...

"I hope Noah's not discouraged about getting cut. He's really improved his game this past year. He's obviously a hard worker and definitely has potential in lacrosse."

The Coach continued:

“...but we felt he was missing the speed to play at this level. Not only that, if he added some strength to his game, it would make him harder to play against and let him get gritty in those physical areas. He's got the skills and high potential to be an impact player, I think if he got into some quality strength & conditioning it would be like pouring rocket fuel on his development."

That's when he recommended checking out Coach Kyle & Relentless Lacrosse. We had worked with thousands of youth athletes at this point & earned a reputation for our work developing elite lacrosse players.

Noah's Dad knew the importance of strength & conditioning as players got into high school. But was hesitant working with a trainer, having seen Noah previously work with a local old school personal trainer who acted more like a Drill Sargent, putting kids through sloppy circuit training, than a Coach developing true athletic foundations.

Noah, like most motivated youth lacrosse players, didn’t need this.

He didn’t need a trainer to push him harder, he needed a game plan to make sure his work created results.

So that’s what we created for Noah – a 12-week game plan to develop the foundational strength and power he needed to thrive as an athlete, as well as the exact attributes that translate most to the field.

With the right guidance, Noah's work started to pay off. 

He started to look more like an elite player – more explosive, agile, and dynamic. He was strong on the ball and outmuscled other kids for ground balls. He never seemed to run out of gas. He went from occasional goal scorer to being the goal scorer. 

It started with coaches and other parents joking with the classic “what are you feeding that kid!” 

But the jokes quickly became serious conversations about what he was doing, what camp had he been going to, what coach he worked with – where did he find the edge?

The truth is, there was no secret sauce. No coach that was going to turn him into an elite lacrosse player. No workout that magically got him stronger.

It was Noah’s hard work applied to the right game plan.

That next season, Noah not only made that elite club but was an impact player all season, finishing third on the team in points. He also started on his JV team in his freshman season and even played varsity games.

At the time, we had created digital programs that were being used by pros and college players, but seeing Noah's results made us realize that youth players needed a blueprint to give them the exact structure they needed to develop into elite hockey players.

They had the ambition; they just needed the game plan – and that's when the Relentless Youth Development Program was born.

Since then we’ve had thousands ambitious youth players translate their hard work and hustle into true athletic development that gives them not only the advantage over players now, but long term.

We've been fortunate to watch many of these players unlock their potential to go from youth to varsity, earn scholarships, and continue to thrive in the game.

If you have a youth lacrosse player at home that's serious about becoming the best player they can be, then now is the time to start getting relentless with their training!

Seems expensive, why 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 ice. 

Working with a Strength Coach that understands the specific needs of lacrosse players can cost upwards of $150+ 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 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.

What kind of equipment do I need?

This Relentless Youth program was designed to be performed with a super basic gym setup. We don't believe in big fancy gym setups or the flashy equipment.

While some players use a community rec centre or commercial gym, we've actually had an equal amount of players do this program at their home or garage gym. This program doesn't require machines or squat racks. All we need is:  dumbbells, cables/bands, kettlebells (can use DBs instead), a bench, a stability ball, and mini-bands.

We also have an exercise substitution guide for any equipment you might not have!

How do I access my programs?

Immediately after purchase you’ll have access to our members-only platform that contains all of your training programs and bonus resources. You’ll have lifetime access to this platform and will be able to come back any time to download your programs or get updated versions/new resources.

What if I’m not happy with the program or results?

We stand by our programs 100%. That’s why we offer a 100% satisfaction guarantee. Having seen thousands of players train with Relentless, we know lacrosse players who truly invest in this program and their training get results. But if you start this program and it’s not for you, just contact our team within 30 days and we’ll send you a full refund. 

What age of player is this for?

This program was designed for players under 15. While older players can and have used this program - we typically recommend they move to one of our more advanced programs if they have gym experience.

I coach high school lacrosse and just had my younger guy go through your relentless youth program. I want to make this training a prerequisite for all my future players. This is exactly how young lacrosse players should be training to create the foundations they need to thrive in this game. I’ve reached out to Kyle about building something for our high school program because I really thing these guys are best in class when it comes to lacrosse training.

Don’t delay! It’s 100% worth the cost!! Okay for the moms (like me) that don’t want to spend money on something that isn’t going to ACTUALLY help their kids (or that they’ll enjoy) let me break down it.. THE GOOD: they clearly spent hundreds of hours building the programs the workouts really address everything (including speed and mobility), the exercises aren’t just “weight lifting” or bodybuilding, every time I checked in on their workouts I saw them doing some cool exercise (that I eventually stole for myself). THE BAD: I wouldn’t say there’s anything toooo bad.. Only downside is that sometimes the workouts are a little bit long, like 60 min+ (my kiddos would probably prefer 45) butttt I never had to prompt them, they always enjoyed the workouts and did them to completion (even the stretching which i was shocked with!!). Maybe better suited to kids that have done some training before? (my kids havent done a ton, but had been in the gym with their hockey teams). OVERALL: definitely worth the purchase, I love that it’s taught them to actually workout properly and they’ve said it’s definitely made them stronger and more powerful on the field which they love. We’ll definitely be repeating this program (loveee the lifetime access) and look to more relentless programs in the future!

This program is worth 10x the investment just in the fact that it teaches kids proper strength & conditioning from day 1 and how to be an athlete. Both of our kids used this (12 & 14) and loved that they had something they could follow that was specifically for lacrosse & we as parents loved knowing that they were doing the right things to become better athletes. Worth every penny.

This is the program that ALL youth lacrosse players in America should be using!! I’m a personal trainer myself but never had any experience training youth athletes or lacrosse players so when I wanted to get my young guy into training I found Relentless Lacrosse and let me tell you.. These guys are the REAL DEAL when it comes to training. The workouts are structured super intelligently, so many exercises I hadn’t seen before (and have since stolen for my clients!!) and is perfectly built for developing athletes. My guy loved his relentless workouts and is noticeably stronger than other kids his age on the field. Coach is calling him the ground ball champ haha! Big thanks for sharing this program!

Our son was told last year that he had the right skills but wasn’t strong enough to play hard teams. He came to us wanting to get into strength training and when I started look around at options out there I found the Relentless program. He’s been using it diligently and put on 12lbs of muscle so far! It’s been awesome to see him get into strength training and the confidence it’s giving him on and off the field.

Hey Kyle, I just wanted to drop a quick note. I’m a physiotherapist so I’m SUPER picky with strength training, but reading through all your articles and seeing your approach to lacrosse training I knew that I had to get your program for my daughters. We’ve all loved going through it. It’s been perfect for them to have something structured to follow and I’ve really seen their progressions both with their training on the field. You have a fan with our family and we can’t wait to use another program next off-season!
