Dick Hartzell, inventor of the FlexBands® and founder of Jump Stretch, has always felt that part of strength training should be done dynamically. One day, during his coaching years, two of his players got injured while trying to train quickly with weights. Coach Hartzell thought there had to be a better way to do this, maybe with rubber. The name "Jump Stretch" popped into his mind.

A couple years later, Coach Hartzell left teaching and coaching to develop the Jump Stretch idea. Within three months, he had the product - a combination of bands and a platform base for doing squats and four other lifts. Two years later the US Patent Office granted his patent.

Initially, the product was called Jump Stretch. Now the bands are called FlexBands® and they are provided by Dick Hartzell's company, Jump Stretch, Inc.

After working from his home for several years, Coach Hartzell and his family now run Jump Stretch successfully from its home base in Youngstown, Ohio, which also features the world's first all-rubberband gym.

Flex Bands are used by:

The Los Angeles Angels of Anaheim, Boston Red Sox, Texas Rangers, Buffalo Bills, Dallas Cowboys, New England Patriots, New York Giants, Pittsburgh Steelers, Seattle Seahawks, University of Florida, Mount Union College, Ohio State University, West Virginia University, US Navy Seals (Since 2002) ..... and many more.
