Productive Fitness Products Inc. was founded in 1996 and incorporated in 1998. Mike Jespersen started Productive Fitness Products Inc. with the publication of The Great Dumbbell Handbook. The idea of publishing a book specific to dumbbells came when Mike was working at a local fitness equipment store in Vancouver, B.C. Many of the customers purchasing dumbbells also wanted a reference guide to performing the exercises. The book was an instant success and has now sold over 300,000 copies. This success has been expanded upon with The Great Body Ball Handbook now having sold over 300,000 copies, and The Great Handbook series having sales of over 1.2 million.
