What It Is
Because you have to control and redirect the weight as it shifts, simple movements become full-body training.
A dumbbell only moves when you move it. This keeps moving on its own.
Strengthen your core and stay balanced while the resistance keeps changing.
Train your core and upper body while building the conditioning to do more with that strength.
Maintain better movement and control deeper into a workout, game, or active day.

An Original Training Practice
FOB was created by Jah Matt, @jahfobin on IG, who studied Kinesiology for a decade while coaching in gyms, physical therapy clinics, and his own private training. He built and tested the FOBand himself, so the equipment and the method were developed simultaneously. New movements and progressions are still being developed.
For now FOB can only be performed through supervised sessions. Jah has made it a point to gamify the session structure, so as you learn to control the FOBand you’re also having an enjoyable experience.
