Palm Beach County native, Karlvyn Louis-Charles, better known as Coach K, is helping the next generation of athletes become stronger, faster, and more agile. He graduated from Cardinal Newman in 2008 and continued his studies at University of Central Florida (UCF), where he earned a degree in exercise science. 

After finishing his education at UCF, Coach K returned to West Palm Beach to start his journey in the sports world. His 12 years of experience, includes:

• Zoo Health and Fitness (Trainer, Class Coordinator)
• Nexx Level (Trainer)
• Synergy Fitness (Trainer)
• Forest Hill High School (Head Coach – Strength and Conditioning, Assistant Coach – Girls Basketball)
• Cardinal Newman (Assistant Coach – Strength and Conditioning)
• Palm Beach Central High School (PBC)  (Head Strength and Conditioning Coach, Head Coach – Girls Weightlifting, Assistant Coach – Boys Weightlifting)

In the past 5 years, Coach K has built his own brand, Kinetic Synergy Performance. His passion for helping student-athletes started in high school when he fell in love with “the idea of fine-tuning the human body like a car.” Now, he works with over 130 people every week, including nearly 90 athletes from Palm Beach Central alone.

This is Coach K’s 4th year as PBC’s Head Coach for Girls’ Weightlifting, and it’s been the best year yet. Every member of the team qualified for Districts and the team  totaled 12 medals.  The  six lifters advanced to Regionals. Overall, the team placed 5th (Olympic), 6th (Traditional), and brought home 5 medals, all of which broke previous school records. Ariana Rauch and Kimberly Berg both made it to states, where Kimberly won 2 state medals. Coach K also had an athlete from Royal Palm Beach High School, Skye Zwirner, make it to states.

In 2021, Coach K created an athletic group which works with him three days a week. Over the last two months, he’s noticed something special about this group. Each athlete has 8-9 personalized workouts designed for them specifically geared to their sport. These athletes come from different schools, play different sports, and range in age. But when they come together, the energy in the room is unmatched. Everyone cheers each other on, pushing one another to get one more rep or hit a personal record.

Coach K’s number one goal is helping athletes improve in any way, whether it’s speed, technique, flexibility, or pure strength. Some of these athletes include:

• Andrew “Drew” Ulysse (PBC Football):
  While working with Coach K, Drew has not only gotten stronger (PR bench 290), but he’s also dramatically increased his hip mobility. Drew says Coach K has helped him become a “better overall athlete” and “keeps me honest.”
• Caden Greeley (PBC Football + Weightlifting):
  Caden has been working with Coach K for two years through football, but Coach K introduced him to weightlifting, and Caden fell in love with the sport. Caden says, “I kept getting better with his coaching, and I just love weightlifting.”

To improve speed, Coach K tracks Palm Beach Central football players every three weeks using the flying 10 test. The most recent test, on March 19th, showed several athletes made major improvements, with some even reaching over 20 mph. Here are some of those improvements:

• Cyre Blake:
  • 2/4: 18.77 mph
  • 2/25: 19.12 mph
  • 3/19: 19.86 mph
  • Total Improvement: +1.09 mph
• Ariel Lariviere:
  • 2/4: 18.94 mph
  • 2/25: 18.94 mph
  • 3/19: 20.25 mph
  • Total Improvement: +1.31 mph
• Jurvensky Dagrin:
  • 2/4: 18.77 mph
  • 2/25: 19.86 mph
  • 3/19: 20.05 mph
  • Total Improvement: +1.28 mph

When asked about the future, Coach K simply said, “expand.” He wants to either expand his current space or open a second location so he can work with even more athletes. Coach K is helping the community, one athlete at a time, and shaping the next generation of All Stars.
