Training Fastpitch athletes is much different than training baseball players.  Most strength and conditioning programs do not consider the differences between a female athlete vs. a male, much less a slap hitter or softball pitcher vs those of their baseball counterparts.  The game is different, as are the needs of the athletes who play them.  Because of the smaller field dimensions and shorter bases- reaction time, first step quickness and power output all have a heightened need.


with less attention being paid to number of pitches thrown during a weekend tournament (vs. a baseball pitcher)– leg strength and muscular endurance are critical to helping a pitcher keep their shoulders healthy.  Arm care and recovery are part of the training puzzle for the pitcher.  A combination of private training and small group speed work are suggested.  We typically conduct a functional movement screen specific to the overhead athlete as part of our program recommendations.

Hitting and Fielding

to aid our hitters and fielders excel we incorporate Senaptec Sensory Training (helping the brain react more quickly to what the eye’s see), speed, agility and functional strength.  Most of this can be completed in a small group setting, but private training might be warranted if the athlete has had orthopedic issues such as ACL, shoulder, lower back, or hamstring strains.         

Nutrition Coaching

many of our female athletes struggle with eating for performance and how to properly fuel to gain lean body mass.  Our team of sports registered dietitians are attuned at motivating, educating and providing accountability to help the female athletes make the necessary adjustments to fuel and hydrate their bodies for tournaments, recovery and to make the appropriate body composition changes (weight loss, muscle gain, etc).  Team lectures available. 

Why chose AR?

We would do our best to work directly with your coaches, skills instructors, and medical team to understand exactly what you need to improve on.  Our speed program is unparalleled in our industry.  Blending strength, sensory, agility and speed into a comprehensive program is exactly what our fastpitch players need to improve their game- no matter what level they are.

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.

tennis training- Athletic Republic St. Louis


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.
