The popularity of the kBox among coaches who strive to develop baseball players’ strength is growing and it is already used by several Major League Baseball.

With flywheel training on the kBox, coaches get a tool for both general and sport-specific drills to target starting power, sprint speed, core strength and shoulder health.


In baseball the kBox is mainly used for lower limb strengthening and shoulder health, which can often be combined. The ‘single arm lunge row‘ is an excellent drill for engaging the muscles responsible for throwing, in addition to the many traditional lower body exercises such as squats, lunges, lateral squats and split squats. Useful upper body exercises, besides the aforementioned rows, include pulls and shoulder press exercises among other general movements.


With access to the kBox, after only a short familiarization period users can achieve a robust stimulus regardless of training age. Being able to work around injuries to arms, elbows and shoulders by using the harness during your leg training is also a major benefit.

More specifically the Exxentric Harness reduces a lot of the torque and stress on the lower back and unloads the extremities in the upper body. Easy and safe to perform and monitor with the kMeter in a team setting. The kBox’s portability has made it a favourite for many coaches in Pro sports since they can easily carry it with them throughout the duration of the competitive season.


Baseball teams already applying the kBox include the following MLB teams: Atlanta Braves, Arizona Diamondbacks, Baltimore Orioles, Houston Astros, Los Angeles Dodgers, New York Mets, San Francisco Giants and St. Louis Cardinals
