A spherical hand exerciser has a resilient, non-slip exterior with an off-center cavity and a weighted core housed within the cavity. A method of performing physical therapy with the exerciser includes grasping at least one exerciser; and manipulating it around the hand and fingers. The offset placement of the weighted core works stabilizer muscles of the fingers, hand, wrist, and forearm during manipulation, increasing the synergy and workable range of motion of both the flexor and the extensor muscles, allowing for faster learning and better effects.

An information processing apparatus (100) according to the present application includes two or more force sensors (110) that each detect a force of two or more different fingers of a user, and a processing unit (122) that executes information processing related to measurement of forces of the two or more different fingers based on detection results detected by each of the two or more force sensors (110).

A force measurement mechanism comprises two force input members (105, 106), a pair of cantilever springs (101, 102), and a force measuring means (107). One portion of each cantilever spring is held by a first constraint means (103) and one portion of each cantilever spring is held by a second constraint means (104) with each cantilever spring having an unconstrained length between the first and second constraint means that is free to bend. The constraint means (103, 104) hold the cantilever springs (101, 102) in a parallel and spaced apart arrangement. The force input members (105, 106) are attached via the constraint means so that relative movement of the force input members bends the cantilever springs (101, 02), and the force measuring means (107) is arranged to measure force applied between the force input members.

A method is disclosed for using an artificial intelligence engine to modify resistance of pedals of an exercise device. The method includes generating, by the artificial intelligence engine, a machine learning model trained to receive measurements as input, and outputting, based on the measurements, a control instruction that causes the exercise device to modify, independently from each other, the resistance of the pedals. While a user performs an exercise using the exercise device, the method includes receiving the measurements from sensors associated with the pedals. The method includes determining, based on the measurements, a quantifiable or qualitative modification to the resistance provided by a pedal of the pedals. The resistance provided by another pedal of the pedals is not modified. The method includes transmitting the control instruction to the exercise device to cause the resistance provided by the pedal to be modified.

A grip exerciser has a first handle, a second handle, a connecting member and a spring. The first handle and the second handle both have a pivoting portion and a holding portion, a pivot is disposed through the pivoting portions of the first handle and the second handle to assemble the first handle and the second handle together; the first handle further has an escaping space at an inner edge for accepting the connecting member, and the second handle further has a closed surface at an inner edge; the closed surface further has a plurality of positioning protrusions located along a continuous line and capable of engaging with one end of the spring;
