Rotation resistant exercise device

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 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 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 and the second housing when a user generates rotation between the first housing and the second housing.

A spherically shaped exercise device comprised of an interconnected first hemisphere and a second hemisphere, arranged to enable concomitant muscular engagement of core, chest, back, shoulders, hips and lower body muscles, and arms and hands, by palm-facing-palm engagement of respective ends of the device, the device comprising:

• a first and a second hemispherical-shaped palm-to-palm-facing-enabled grippable housing arrangement resistively-rotationally joined about an elongated bolt having a first end secured to the first hemispherical housing and a second end secured within the second hemispherical housing, the elongated bolt within the second hemispherical housing having a tabbed washer therearound engaging a rotational resistance indicator bracket, the rotational resistance indicator bracket having a protrusion distally thereon protruding through the second hemispherical housing to indicate relative rotative positioning between the housings, and hence set-identifiable rotational resistance of the exercise device;
• a rotationally resistive compressive 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, wherein the rotationally resistive compressive mechanism arranged about the elongated bolt comprises a compressible spring arranged longitudinally there around, wherein the compressible spring is biasable against a second annular hub, the second annular hub being non-rotatively secured within the second hemispherical housing;
• a first annular hub secured within the first hemispherical housing, with the elongated bolt secured within the first annular hub, and, an annularly-shaped friction inducing compressible brake member rotationally unconstrained, pre-compressed, in an annulus between the second annular hub and the first annular hub;
• wherein the rotationally resistive compressive mechanism is arranged between the first and second hemispherical housings to enable adjustable changing of rotational resistance between the first and the second hemispherical housings;
• and
• wherein the rotationally resistive compressive mechanism arranged about the elongated bolt compresses against both the second annular hub secured to the second hemispherical housing and to the first stationary hub secured to the first hemispherical housing, with the compressible brake member arranged in the annulus between the first hub and the second hub to effect rotational resistance therebetween when biased between the first and second hubs.

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;
• and wherein the method includes rotating one housing with respect to the other housing so as to compress or decompress the elongated spring disposed about the elongated bolt between a first hub and a second hub so as to initiate a change in rotative resistance by compressing or decompressing a resistant braking material annularly arranged between the first hub and the second hub, to effect effort requirements for further rotation of the respective housings therewith.
