We Get Training

Riley Beecroft set a goal to break the state record in the 100M dash, with his father and coach, Wes Beecroft, by his side. A weightlifting enthusiast with no experience in sprint coaching, Wes poured himself into learning and training alongside his son. 

Riley broke the middle school record in 8th grade, but suffered a hamstring injury during his high school season. Devastated, Wes dove even deeper into research on training techniques. But he had an ace in the hole — his career in mechanical engineering.

That combination of passion and technical knowledge led to the creation of the Wave Trainer, a product that enables others to pursue their own athletic goals.

That original prototype has undergone nearly five major redesigns and countless tests, all leading to the creation of a new breed of Isoinertial training equipment: Quest. Co-founders Wes and Jeff are proud to offer this game-changing technology, The evolution of the Quest flywheel family is nothing short of amazing, and it's ready to take your fitness to the next level.
