From the Founders of The FIRM!

Sisters Anna and Cynthia Benson — creators and founders of The FIRM, and developers of The FIRM method — are pleased to present WHFN Workouts — featuring 4-WayFusion™.

WHFN FitPrime and KickButt! workouts use equipment you probably already have: a set of dumbbells and a step device. An optional "balance stick" can be created with a simple dowel, a broom or mop stick. To read more about each specific workout, click on "Learn More," below.
