About Us


MaxOut Strength Systems, LLC owns and manufactures the BarwisMethodsTM Tower which is a unique eccentric strength training device that attaches to any commercially manufactured piece of strength training equipment. Our technology provides lift assistance to the user which then allows them to overload the body during the eccentric phase while receiving a prescribed amount of lift assistance on every single repetition.

The Tower technology was created at the University of Florida in the early 1990's and remained under their control until 2007. It was used primarily as a research tool designed to determine the effects of eccentric strength training as it pertained to injury rehabilitation. In 2007, the technology was released by the University of Florida to a group of investors who decided to turn the technology into a fitness business – MaxOut Fitness, one that provided strength training in only one hour per week. While the results were astounding, the business faltered. In 2010, Jason Griggs and Matt Cubbler purchased the company and moved everything to their hometown of Royersford, Pennsylvania.

Jason and Matt reestablished the MaxOut Strength Studio brand while continuing to find ways to improve the technology as well as the methodology that was used in conjunction with The BarwisMethodsTM Tower .


Over the next 5 years, they began making major improvements to the design, function and logic found within BarwisMethodsTM Tower. They continue to find new and better ways to deliver to their customers the best technology that science has to offer.

In 2011, they were fortunate enough to meet Mike Barwis, founder of Barwis MethodsTM, who was and is a world renowned strength and conditioning expert. At the time, Mike was the Director of Strength and Conditioning at the University of Michigan. Seeing an opportunity to advance the functionality of the BarwisMethodsTM Tower, Mike authored the programming for it. He also began using the , BarwisMethodsTM Tower into his strength training program at the University of Michigan and at Barwis Methods in Plymouth, MI. In the last 5 years his athletes achieved record strength gains.
