Rotation resistant exercise device

A method of using a portable, personal exercise device, comprising the steps of:

• arranging a transverse handle on each end of a pair of resistively engaged housings;
• connecting each housing via a compressively resistant spring arranged longitudinally about an elongated bolt, which bolt connects the housings together;
• gripping each transverse handle at the respective ends of the exercise device;
• rotating one handle and housing in one direction and simultaneously rotating the other handle and housing in the opposite direction.

An exercise device arranged to enable concomitant muscular engagement of core, chest, back, shoulders, hips and lower body muscles, and arms and hands, the device comprising:

• a first and a second hemispherical housing arrangement resistively rotationally joined about an elongated bolt having a first end secured within the first hemispherical housing and a second end secured to the second hemispherical housing;
• a rotationally resistive mechanism arranged about the elongated bolt having a second end rotatively arranged within an inner portion of the second hemispherical housing and a first end of the elongated bolt secured to an inner portion of the first hemispherical housing;
• a compression adjustment mechanism arranged between the first and second hemispherical housings to enable adjustable changing of rotational resistance between the first and the second hemispherical housings;
• and
• a first and a second user-gripping-means on both the first and the second hemispherical housings to enable the device user to use a different gripping manner on each respective hemispherical housing of the device.

A spherically shaped, opposed palm-grippable exercise sphere, the exercise sphere comprising:

• a first hemispherically spherically shaped housing and a second hemispherically shaped housing rotatably connected together by an elongated bolt, the elongated bolt having a first end secured within a first inner hub secured within the first housing, the elongated bolt having a second end secured within an elongated nut elongated which elongated nut is secured within an anti-rotational sleeve within the second housing;
• a second inner hub secured to the second housing, with a compressive spring arranged around the elongated bolt, the compressive spring disposedly spaced between the second inner hub and the elongated nut so as to enable the bias of the second inner hub towards or away from the first inner hub;
• and
• a disk-shaped annular brake member arranged in an annulus between the first inner hub and the second inner hub so as to create an adjustable controlled rotational resistance between the first housing in the second housing when a user generates rotation between the first housing and the second housing.
