Abstract: The spherical dynamic resistance device enables simultaneous strength, core and cardiovascular training. A cavity exists whereby resistance bands are stored. By removing a band and connecting it to the exterior of the device at an attachment point and thereafter attaching the other end of the resistance band to a fixed point a user can engaged device to conduct a full body workout. The cavity can also retain a mass element adding weight thereby customizing the weight of the spherical dynamic resistance device. A serpentine channel associated with the outer portion of the device enables a user to grip the device while engaging hand, arm and core muscles. By gripping the device and through various motions that pull opposite of the resistance band while supporting the spherical dynamic resistance device of various weights, a user is able to attain a full body workout.
