GABBI MARTINEZ – MARQUETTE UNIVERSITY

I’ve had too many coaches and trainers to count over the course of my athletic career but I’ll always give the credit of my high school performances to David Granson. He values discipline, intensity, and accountability, and it shows in his training. I left every session feeling accomplished and smiling because of the tone he sets and the energy he brings to the gym. Working with someone who is passionate about what they do makes all the difference in training as an athlete. It was clear that he was invested in making me better as an over all athlete and it showed in my play. I went into my division one volleyball program ahead of the curve in the weight-room with a strong foundation and familiarity with the work ethic needed to be successful. – Gabbi Martinez

TAYLOR FLAHERTY – COLGATE UNIVERSITY

“Coach Granson was my weight room coach in high school. His work ethic and drive to push athletes to their full potential makes him such a great coach. He is passionate about working with both men and women from various sports, to further their abilities. When I trained with him, it was clear that he was invested in every kid and worked hard to make us all the best we could be. My personal training experience with Coach Granson was wonderful. I always felt like he pushed me to the best of my ability and his workouts were always a challenge. Even through the tough workouts, Coach Granson made an effort to get to know me and the other athletes on a personal level. He brings a perfect amount of toughness and competitiveness to the weight room, always bettering the athletes that walk into his gym. I am the volleyball player I am today because I trained with Coach Granson!”
-Taylor Flaherty

MAX MANGUM – HARVARD

JAKE COKER – COLORADO SCHOOL OF THE MINES

“Coach Granson helped me prepare for college football by putting me through a balanced strength, speed and conditioning program. Coach was very effective in teaching the proper technique for various field tests including the pro-shuttle and forty. I saw nearly a 3 tenths of a second improvement in my forty as well as a vast difference in my on-field stamina. In the weight room, I experienced increases in power clean, squat, and bench and he had trained my mind to push my body further than I thought it could. He knew when to encourage, when to discipline, and was extremely effective at preparing me for the college level. Thank you Coach!” – Jake

BAILEY HOLLE – TEXAS STATE UNIVERSITY

“Working out with Coach G not only made me stronger, faster and more explosive, but he also made me love working hard and getting better. Everyday he would make grinding in the weight room fun and enjoyable, but still pushed us to be our best. He made the jump from high school workouts to college workouts 10x easier, and had us completely prepared for our strength and conditioning workouts at Texas State. I can’t thank him enough!” – Bailey

REED KLUBNIK – YALE UNIVERSITY

“Working with Coach Granson helped transform me in to the athlete I am today, his combination of strength, speed, and conditioning training shaped me physically to be where I am today. He taught me and my fellow players what it means to truly work and give everything we have to be successful. Without him I wouldn’t have been the athlete in high school and I wouldn’t be where I am today.” -Reed

CHASE COKLEY – OHIO UNIVERSITY

I’ve been training with Coach Granson since my sophomore year in high school. I have great respect for him because he not only helps me athletically but he always makes sure I’m getting what I need mentally and he looks out for me. I don’t trust many people but I can count on Coach Granson. I will have a chance at the next level because of G10.

ANDREW BOYKIN – TEXAS A&M UNIVERSITY

“I worked with Coach Granson for three of the most critical years of my athletic career, from when I was a sophomore until I graduated. I can honestly say that I would not be playing at the next level today without his training. His programs always were challenging both physically and mentally, which helped me compete and be successful at the highest level of high school football across the nation.” – Andrew

KYLEN GRANSON – SMU

G10 is my life. G10 defines me. I was a lanky uncoordinated kid when I started high school ball. My 9th grade position coach didn’t know my name. My sophomore year I had a “recruiting specialist” tell my mom that if I were to ever play college football, Division 3 was it. My junior year I barely played at all. Then I broke my leg before my senior season. Coach Granson told me it wasn’t over. He had a plan. Today, I’m the starting tight end at a Division 1 school and top 5 in the nation in four of the major statistical categories at my position, including #1 in TD receptions. G10 is the truth.

WILLIE ROBERTSON - NORTH CAROLINA

After my senior football season in high school, I needed a place to elevate my game to the next level. By committing myself to G10 every day, I was able to separate myself from the rest of the pack.

LINDSEY HARRIS - HOUSTON DASH

I’m so happy I found Coach Granson and G10! It was the perfect off-season training that I needed to get me stronger and quicker for my next season! It was a fun environment but also a challenging one that was the ideal balance to make me a greater athlete.

MICHAEL GRANSON - GRAMBLING

As a multi-sport athlete for most of my career, Coach Granson always made sure that I understood how training is vital for not only my performance but also my health. Now being a collegiate athlete in only one sport with the knowledge gained from training at G10, I have become stronger and more explosive than I’ve ever been. My body is healthy and I feel great. G10 will always be a part of my athletic life.

LOGAN HULON - HOUSTON

Working out at G10 has made me stronger not just physically but also mentally. I have gained more endurance and power which has helped me in my pitching performance. Coach Granson is a very reliable and positive coach who pushes you to be your best because he wants you to succeed in all aspects.

DOAK WILSON - TEXAS

Training at G10 changed me as an athlete in far more ways than I thought was possible. I was pushed daily to test my limits in both the weight room and on the field, and the results that came from that were well worth the work put in.

DALTON FISH - SOUTHEASTERN LOUISIANA

G10 has helped me take my collegiate game to the next level. Coach Granson really takes the time to focus on what you need individually and push you to be your best.
