A rotation exercising ball structure includes two shells, two pivot seats, a weight unit, and two handle protecting members. The two shells are combined to construct a hollow ball. Each of the two shells has a space. Each of the two pivot seats is formed on the space and has a through hole. The weight unit includes a mandrel, a rotation member, two bearings, and a weight. The mandrel has two ends each secured in the through hole of one of the two pivot seats. The rotation member has a first end provided with a mounting hole for mounting the two bearings. The weight connects a second end of the rotation member. The rotation member and the weight are rotated on the mandrel. The two handle protecting members are mounted on the two shells.

The present invention relates generally to the field of exercise devices. More specifically, the present invention relates to a total home physical therapy device that can be used to perform physical therapy exercises. The device is primarily comprised of at least one handle, a body, at least one spring, and at least one ball. The handle can be held in the hand of the user such that the ball can be inflated and can be used for inner thigh strengthening exercises that can be performed in a seated or laying position.

The multi-modal portable exercise equipment of the present invention includes a zippered skin and matable first and second generally hemispheric exercise half bodies that in mated condition provide a generally spherical exercise ball. The exercise ball, or another ball such as an ordinary basketball, is inserted in the skin and attached to external exercise equipment such as the cable of an exercise machine or resistance band and can be used by a subject for strength and other allied training exercises. In another exercise modality thereof the first and second generally hemispheric exercise half bodies in unmated condition each provide a freestanding generally hemispheric exercise half body and can be used by a subject for balance and other allied training exercises. The first and second generally hemispheric exercise half bodies in unmated condition are each constituted of a plurality of spherical caps in nested relation that may be unpacked and used by a subject for balance and other allied training exercises of low, medium and high use difficulty.

A training apparatus for training a user's grip and strength. A rod element is disposed through a female tube that is disposed at a first end of the rod. The rod extends through a male tube that is inserted into at least a portion of the female tube. A grommet is disposed on the rod, inside the female tube, and abutting the male tube. A fastening means couple to the first end of the rod, mitigating movement of the grommet toward the first end. A tensioner is rotatably attached to a second end of the rod, wherein when the tensioner is rotated clockwise it presses the male tube forward against the grommet, which is compressed between the male tube and fastening means, expanding inside the female tube. The grommet pressing against the inside of the female tube provides a desired resistance for a user rotating an attached training member.
