"You can't store physical fitness, so you've got to work activity into every week of your life." - Jacki Sorensen

 


What Is Vertifirm?

Vertifirm ExampleStanding-up exercises.   Vertifirm stands for "vertical firmness."  It has revolutionized the fitness industry and made Jacki's the most complete cardiovascular fitness, muscle-toning, and strengthening classes available.  Vertifirm has been incorporated into choreographed combinations to replace spot exercises traditionally done on the floor.   These "standing-up floor exercises" provide the benefits of floorwork, but because you are on your feet, it is possible to work on more than one muscle group at a time.  Most floor exercises waste time by working muscle groups one at a time.  Jacki takes these exercises off the floor and adds upper-body resistance training using optional hand-held weights.  In addition, ankle weights may be used to extend the resistance training to lower body moves.  (Ankle weights are not used in StrongStep™ because the step provides enhanced lower-body resistance.)  If you've never used weights before, you'll be surprised at how enjoyable, challenging, and rewarding they can be.

Abdominal floorwork.  A lean, flat stomach requires strong abdominal muscles and the elimination of abdominal fat.  It is not possible to effectively strengthen the "abs" without lying down and working against gravity.  So, each class has a concise abdominal routine before we stand up and Vertifirm.  The aerobic segment of class attacks abdominal and other excess fat by working out in your "fat-burning" or working heart rate range.

More fun! Vertifirm extends resistance training limits and burns more calories than traditional floorwork.  Best of all, it's lots more fun than floorwork!
