Productive Fitness Products Inc. was founded in 1996. 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 led to many more handbooks.
