At Athletic Republic we give you more than just speed.  The foundation of our success comes from our approach to athlete development. We provide the answers to becoming faster, quicker and more powerful by assessing every athlete’s strengths and weaknesses in the following areas: Movement Skills (speed, agility, stability and symmetry), Power and Strength, Conditioning Efficiency, and Tennis Specific Skills.  From this assessment, our performance trainers create a personalized performance sports training program that balances the time of year, sport(s), position(s) played, physical development, skill level, performance level and goals.


We work closely with your tennis pro to understand your needs on the court.  While your pro works on your technique, game strategy and court senses, we provide you the athleticism to better apply what your pro is teaching.  In essence, we provide you the hardware so you can better download the software taught by your pro.  Our program will help you reach shots you may not have run down before; change direction more quickly; serve with more power; be more agile during net volleys and be in better anaerobic condition for long matches and tournament play.

Part of our teaching could involve the services of a sports registered dietitian to help you understand fueling for recovery and performance.  We are versed at exercising/hydrating in the heat, tournament participation and eating to gain strength and power.


Training a tennis athlete takes the same care that we utilize with our other overhead athletes (think baseball pitcher) coupled with the anaerobic and agility required of a soccer player.  In an ideal world, we would address these needs with a combination of small group speed and agility work combined with private training to address the specific needs of the tennis athlete.

Our coaching is in two forms- small group speed, agility and functional strength classes which are ideal for the athlete needing conditioning and quickness and is free of orthopedic issues. For those tennis athletes needing corrective and specific exercise programming, we would suggest private personal training so we can implement exercises derived from the assessment.

Our training staff has advanced education in exercise science, nationally recognized certifications and has competed at elite levels of various sports.

Tennis- Athletic Republic St. Louis


We can provide the assessment and private training at either Athletic Republic- St. Louis or at our training location in Creve Coeur Racquet Club.  Small group training takes place at our Athletic Republic- St. Louis.


Any tennis athlete who desires to improve their game.  An adult tennis player is well-suited for private training so we can really address specifics to keep them on the court.  A youth player will benefit the most from a blend of small group and private training.  We are more than happy to teach programming and let an individual run with it.  We happily work in conjunction with your tennis pro to best understand your conditioning needs on the court.

Sport-Specific Training

Many aspects of the Athletic Republic Acceleration Training programs are universal to all sports, designed to develop overall athleticism and resilience, but we also recognize that each sport and discipline has specific demands. We address those needs not only with our individualized “One Size Fits One” approach to training, but with extensive sport-specific protocols developed over nearly three decades of training athletes.


We take football training far beyond the standard weight room. Our football training for prepubescent athletes focuses on developing coordination, agility and speed since muscle mass develops later in a young athlete’s life. As athletes mature and the level of competition increases, training focuses more on the development of power/strength and running efficiency. Professional players spend the largest portion of time on power/strength development, but still spend time working on movement skills and running efficiency.

Baseball / Softball

Baseball and fastpitch softball are games of inches that require split-second reactions, instinctual skills and lightning fast agility. By focusing on speed, power, and agility we can give every baseball player the tools to be more successful on the field, regardless of their position. Our training improves rotational strength and stability to develop hitting with explosive power. Pitching velocity is increased by strengthening the acceleration and deceleration muscles used for every throw, while at the same time we focus on arm health for longevity. Our dynamic stability training develops the body control that is essential for making a defensive play.


Every basketball game is made up of hundreds of short bursts of speed; our basketball training works on improving sprinting efficiency and speed using our high-speed running treadmill. Explosive power translates into the ability to drive to the basket, chase down a loose ball, or leap for a rebound or jump ball; we focus extensively on hip strength to generate the power that informs all aspects of a player’s game. Finally, our basketball training emphasizes dynamic stability so players can maintain body control in all directions and stability under all situations, even at full speed.

ice Hockey

Skating is the foundation of playing hockey. It takes proper skating mechanics, explosive speed, quickness and balance to consistently outmaneuver your opponents and become a top player. This is why hundreds of past and present professional hockey players have trained at Athletic Republic. Using a combination of cutting-edge technology like our Hockey Treadmill, or utilizing hockey powercords to facilitate optimal nerve and muscular stimulus, our hockey athletes come away with significant improvements in skating efficiency, coupled with improved puck-handling and shooting movements.

field Hockey

The game of field hockey requires players to have sport specific skills, as well as athletic attributes. Working on becoming an athlete can be a very significant aspect of the game. Field hockey requires speed, quickness, explosive power, as well as strong aerobic endurance. A solid aerobic endurance base will help a field hockey player with the repetitive series of high intensity movements and exercise required to play at a high level.


As the preferred training partner to the US National Lacrosse teams, we understand what it takes to become the best athlete and lacrosse player: the right mix of lacrosse specific skills, enhanced speed, agility, quickness and power. It is essential that a lacrosse-specific training program balances the rigours of lacrosse’s heavy endurance load, while establishing an elite speed-program rooted in acceleration training. Our program focuses on advanced level conditioning, strength training, as well as speed and agility work that translates to both sides of the field in lacrosse.


We’ve developed a unique program to specifically train soccer players to improve their acceleration, agility and power so they can become not just better athletes, but better soccer athletes. Through our evidence-based training protocols and patented equipment, we can improve an athlete’s mechanics so they have a faster first step, can change direction quicker, and have the stamina to play as well in the opening minutes as the closing minutes. In addition, they develop the dynamic stability that is crucial to becoming more resistant to lower-extremity injuries.

The quick change of direction required in a top level tennis athlete is almost unparalleled in other sports. Athletic Republic speed and agility work performed on our patented Super Treadmill and Plyofloor elevates muscle coordination, footspeed, and movement precision to facilitate that next-level change of direction. On average, a 20% gain in peak force and power provides another level to a tennis athlete’s game. And the unique Plyo Press Machine allows tennis athletes to take explosive power training to a higher level.


Our training protocols for volleyball players to improve their acceleration, power and on-court agility for success on the court. We can improve an athlete’s mechanics so they rise higher with more hang time giving them more explosive power behind every hit. We also provide exact neurological learning and coordination that improves functional volleyball strength and the ability to set, pass, serve, spike and block, as well as improve take-off and landing mechanics.
