Stability and strength training device
A transformable exercise device used both for stability and strength training is disclosed. Embodiments include a main portion comprising a sphere that may be used wholly in the manner of a medicine ball, kettlebell, rolling device, or separated into two hemisphere elements and used for various exercises including push-ups, standing balance, agility training, and weight training. The two hemisphere elements may be easily and securely locked together with a U-shaped locking mechanism that, when actuated, is congruent with the surface of the sphere to create a medicine ball configuration. The locking mechanism may be modified with various handle attachments, or removed and replaced with separate components added externally to the device providing various hand or foot placements, or alter the nature of the exercise equipment. The device may be used in conjunction with current technology to provide visual and auditory feedback on user's balance or repetitions while performing exercises.
1. A transformable exercise device comprising:
a pair of hemisphere elements wherein each element comprises a rounded outer surface, a flat grooved surface, and a large recessed centralized cavity; and
a horizontal cross member traversing the large recessed centralized cavity, below the flat grooved surface, comprising:
a hand grip;
a locking aperture for accepting at least one of a locking tab, a spring-loaded push button, a spring-loaded ball plunger, and a spring-loaded button of an exercise attachment;
an attachment aperture at each terminus of the horizontal cross member extending from the horizontal cross member to the rounded outer surface;
wherein each of the pair of attachment apertures is configured to receive an exercise attachment; and
a pair of U-shaped locking mechanisms, each of the pair of U-shaped locking mechanisms including two arm portions, each of the two arm portions configured to fit into the attachment aperture of the horizontal cross member of each of the pair of hemisphere elements when conjoined into a medicine ball configuration, locking the pair of hemisphere elements into a spherical shape.
2. The transformable exercise device of claim 1 , further comprising a kettlebell handle attachment inserted between a pair of grooves on the flat grooved surface of each of the pair of hemisphere elements conjoined in the medicine ball configuration and locked in place with the U-shaped locking mechanisms providing a kettlebell device.
3. The transformable exercise device of claim 1 , further comprising a pair of foot plate attachments, each of the pair of foot plate attachments inserted into the attachment aperture at each terminus of the horizontal cross member of the hemisphere elements, and locked into place with the spring-loaded push button traversing the locking aperture of the horizontal cross member, providing a lower extremity balance device.
4. The transformable exercise device of claim 1 , further comprising a pair of handle bar attachments, each of the pair of handle bar attachments inserted into the attachment aperture at each terminus of the horizontal cross member of the hemisphere elements and locked in place with the spring-loaded push button traversing the locking aperture of the horizontal cross member, providing a wide grip, single fulcrum push-up device.
5. The transformable exercise device of claim 1 , further comprising of a spinning handle bar attachment inserted into a pair of grooves on the flat grooved surfaces of each of the pair of hemisphere elements conjoined in the medicine ball configuration and locked in place with the U-shaped locking mechanisms providing a rolling device.
6. An exercise device comprising:
a first hemisphere element having a first recessed cavity with a first horizontal cross member traversing the first recessed cavity;
a second hemisphere element having a second recessed cavity with a second horizontal cross member traversing the second recessed cavity;
a locking mechanism to lock the first hemisphere element to the second hemisphere element in a locked ball configuration,
wherein the locking mechanism is a U-shaped locking mechanism, and
wherein the locking mechanism includes at least one component connection aperture centrally located within a base element of the locking mechanism; and
the first hemisphere element and the second hemisphere element locked in the locked ball configuration, a kettlebell handle attachment inserted into the at least one component connection aperture of the locking mechanism providing a kettlebell device.
7. The exercise device of claim 6 , wherein the first hemisphere element includes a first interlocking surface and the second hemisphere element includes a second interlocking surface, where the first interlocking surface engages the second interlocking surface in the locked ball configuration.
8. The exercise device of claim 7 , wherein the first interlocking surface and the second interlocking surface are grooved surfaces.
9. The exercise device of claim 6 , wherein the first hemisphere element includes a first opening and the second hemisphere element includes a second opening and where the first opening and the second opening are positioned to receive the locking mechanism in the locked ball configuration.
10. The exercise device of claim 6 , wherein the locking mechanism includes at least one actuator lever.
11. The exercise device of claim 6 , wherein the locking mechanism includes a first arm portion to extend into a first opening of the first hemisphere element and a second arm portion to extend into a second opening of the second hemisphere element.
12. The exercise device of claim 6 , wherein the locking mechanism is flush with an outer surface of the exercise device when in the locked ball configuration.
13. The exercise device of claim 6 , wherein each of the first recessed cavity and the second recessed cavity includes a plurality of smaller recessed lateral cavities, each smaller recessed lateral cavity configured to house an additional weighted member.
14. An exercise device comprising:
a first hemisphere element having a first recessed cavity with a first horizontal cross member traversing the first recessed cavity;
a second hemisphere element having a second recessed cavity with a second horizontal cross member traversing the second recessed cavity;
a locking mechanism to lock the first hemisphere element to the second hemisphere element in a locked ball configuration,
wherein the locking mechanism is a U-shaped locking mechanism, and
wherein the locking mechanism includes at least one component connection aperture centrally located within a base element of the locking mechanism; and
a spinning handle bar attachment inserted into the at least one component connection aperture of the locking mechanism while in the locked ball configuration.
