About Us

Martin Guillet, Director

Our Director, Martin Guillet is certified as a personal trainer with AFAA and ACSM. He is the Associate Director of Recreation in charge of Fitness and Personal Training for 18 years with LIU Post (formerly CW Post). He also works as one of the strength and speed coaches for many of their athletic teams and athletes. Over the last 18 years he has coached athletes from Women’s Lacrosse, Field Hockey, Softball, Swimming, Basketball, Baseball, Soccer, Football and Men’s Lacrosse. Martin has trained over 65 NCAA All Americans (24 for multiple seasons), 4 National Champion teams and 19 Players of the Year at their position.

For many years as a Strength and Conditioning Coach, Martin did as many other Strength Coaches do and gave team programs out seasonally. Every player had the same lift. He noticed that not everyone was showing the same improvements. While all got stronger, not all of them saw a difference as players. He decided to start individualizing everything for the athletes. The athletes started to improve dramatically. It has become the basis for our training style.

He was fully invested in learning as much as he could about the athlete’s individual needs and in making sure they got the proper training.  I first met Martin when I was the head coach of a womens’ swim team and in need of a trainer. Martin took the time to sit with me and go over the various types of training we would need in the gym relative to each athlete’s stroke and distance they swam. He was fully invested in learning as much as he could about the athlete’s individual needs and in making sure they got the proper training. The team very quickly believed in him and in the program he designed for them. I believe Martin was a key factor in the overall success of our team that year.

She looked forward to every session and knew he was helping her become stronger, better swimmer. My daughter is a competitive swimmer and was in need of a trainer while in high school to help strengthen some weaknesses and instabilities. I brought her to Martin and he was awesome. She looked forward to every session and knew he was helping her to become a stronger, better swimmer. He figured out exactly what she needed as an athlete and was strong, but kind and helped to build her self confidence. She is now on scholarship for swimming at the collegiate level and she still tells me that Martin was the best trainer she ever worked with. There is no one else we would recommend as a trainer to any swimmers out there!

With Martin there was no wasted time or energy. All lateral and burst movement training was actually broken down for my position on the field as an attackmen. Because of Martin’s knowledge of lacrosse, the shooting drills incorporated into footwork and speed burst training were the best I’ve ever done. I can directly attribute a lot of his training to my success as a player. Long Island Speed and Strength Training helped prepare me to become a High School and College All American, and be selected as a member of the Gold medal winning US U-19 National lacrosse team last summer.

MARTIN HAS WORKED WITH MY COLLEGE SOCCER PLAYERS FOR SEVEN YEARS NOW. HIS ATTENTION TO DETAIL IS SECOND TO NONE. He was able to give each player an individualized workout that challenged them and pushed them to access their full potential. Martin did a great job of addressing the player’s needs and make changes as they progressed. He was able to focus on strength, speed and footwork through their sessions together. If someone was falling behind on a particular aspect, he met with them, on his own time, to help get them where they needed to be. Martin helped our players get to the next level.

IF YOU TELL MARTIN YOUR GOAL ON OR OFF THE FIELD - HE WILL MAKE SURE YOU GET THERE... JUST BE PREPARED TO WORK YOUR BUTT OFF. When I first joined the DII Women's Lacrosse team at LIU Post I was overwhelmed by the speed and athleticism of the girls I was suddenly playing against. I didn't want to be "on their level" - I wanted to surpass it. Martin took that and ran with it. He tailored speed and strength training to my position and goals on the field. I could tell how much thought he put into fine tuning my strengths and exposing weaknesses that needed to be worked on... My senior year I told him I wanted to be unbeatable in a 1 v 1 so we drilled the components of this for months. By the time lacrosse season came my body was both quick and strong enough to lock out the number one attacker from scoring a single goal on me. I was named 1st All -American and Defensive Player of the Year in DII. If you tell Martin your goal on or off the field - he will make sure you get there... just be prepared to work your butt off.

Speed Work

There are many things that can cause a lack of speed and/ or agility, but it is addressing each individual’s weakness that will produce the greatest results. After we diagnosis the issue, we then teach you the drills and progressions in which it can be translated through their play. Here are some examples of movements we will incorporate to help you reach your full potential:

MARTIN INSTILLED IN ME THE TRUE MEANING OF WHAT HAVING WORK ETHIC ENTAILS. Going into my freshmen year of college, I had some experience lifting and knew of its importance in relation to optimal performance on the lacrosse field. However, working with Martin and learning from him brought my knowledge to an entirely new level. During my sophomore year, I was named All-American for the first time and was voted as the National Defender of the Year. I can honestly say that those accolades would not have been possible without Martin... Not only did he teach me the basic fundamentals of working out, and the importance of footwork and agility, but he also instilled in me the true meaning of what having "work ethic" entails.

WHEN WE SEE MARTIN COMING OUT TO OUR PRACTICE WE ALL KNOW WE ARE GOING TO GET OUR BUTTS KICKED. Most people can probably say they have developed a love hate relationship with him. We all love seeing Martin, but when we see him coming out to our practice we all know we are going to get our "butts kicked". At the end of the day though we all know he does it for one thing and one thing only and that is for us to be the best of the best!

He creates programs unique to each athlete, allowing for optimal efficiency and complete performance from everyone he works with...

I credit a great portion of my playing success to the time I spent working with Martin. He was dedicated in helping me achieve my goals and for that, I will be forever grateful!

Socially Distanced Team Trainings

Through these difficult times, we have to find safe and responsible ways to challenge our athletes. Our team speed is broken up into multiple groups, focusing on plyometrics, first step quickness, footwork, agility, and in sport speed. Within each group there will be 4 or 5 movements to help reinforce our lessons. Individual athletes will be appropriately spaced through each drill and will rotate as a group until they have all completed each of the exercises. The exercises are different each time we meet, and stress the most important and often used aspects of play for the sport you are working towards.

STRENGTH TRAINING, TEAM BUILDING, AND COMMUNICATION FUNDAMENTALS THAT ULTIMATELY MADE US A CHAMPIONSHIP TEAM. Martin put me through workouts specifically geared towards my position as a midfielder and draw control specialist. At many points the workout was so hard I wanted to cry and leave, however, by going through these mentally and physically challenging workouts I thank Martin because I was named a member of the All-American team in 2006. Martin designed boot camps for our team and came up with lacrosse specific speed and agility drills... Accompanying these drills were strength training, team building, and communication fundamentals that ultimately made us a championship team.

I HIGHLY RECOMMEND MARTIN TO ANY ATHLETE WHO IS TRYING TO TAKE THEIR GAME TO THE NEXT LEVEL. Martin has been fantastic for both of my kids. His initial written diagnosis of each player's strengths and development areas after their first session was spot on. As a lacrosse coach and former player, I was extremely impressed with that. Every training session has been geared to making them more explosive athletes, as well as incorporating it into game-like lacrosse situations. His demeanor and teaching methods with our kids has been outstanding. Martin has also actually attended a few of my kids tournament games this summer, giving them real-time feedback on the sideline... I have never heard of another trainer doing that. I would highly recommend him to any athlete who is trying to take their game to the next level.

MARTIN NOT ONLY MADE ME PHYSICALLY STRONGER AND FASTER BUT, HE MADE ME MENTALLY TOUGH AS WELL. When I showed up to C.W. Post as a freshman I had never lifted a weight in my life. All I knew how to do was run and I thought that made me a good lacrosse player. It was when I met Martin that I learned that there was so much more to the game than I had ever realized and I learned that I wasn't as good of a runner as I thought I was. Martin not only made me physically stronger and faster but, he made me mentally tough as well. The best part about it, the workouts were always something new, he kept us on our toes and he is constantly researching ways for you as an individual and for the team to get better. ..Martin sugar coats nothing! He tells you like it is and then pushes you to get past your weaknesses. Martin will push you to a point where you didn't think you could physically more and he proves to you that you can. He does everything it takes for you and your team to reach its fullest potential. I truly owe all of my athletic successes to Martin and I have taken and will continue to take all of the lessons he has taught me through all aspects of my life. Martin is the by far the best motivator I have ever encountered and anyone would be truly lucky to be able to train with a trainer like Martin.

MARTIN HAS EXTREME WORK ETHIC. Working with Martin over the years has helped me reach my full potential, not only as an individual player but as a team player as well. I always dreamed about winning a national championship and becoming an all-American, with the help of Martin’s specific sport training, intense lifts, and team oriented exercises both of my dreams came true, twice. Martin has extreme work ethic. There were plenty of times during the workouts that I wanted to give up, but Martin always knew how to push me and keep me going to reach the level that he believed I could perform and strive at. Without Martin I don’t think I would have been able to reach those milestones in my lacrosse career.
