Provided is a hand grip including a first and second operating arms capable of moving toward and away from each other, a first and second connection arms disposed between the first and second operating arms to be inclined, of which both ends rotatably connected to the first and second operating arms, a spring member installed to provide an elastic force in a direction interfering with approach of the first and second operating arms, a spring fixing part formed to extend upward from the first operating arm and to which one end of the spring member is fixed, a spring connection part formed to extend from an upper end of the first connection arm and to which the other end of the spring member is fixed, and a strength adjusting part formed in the spring connection part and configured to allow the other end of the spring member to move.

A multi-functional sliding grip exercise device, specifically but not limited to: sliding grip medial pull-ups, sliding grip lateral pull-ups, lower back extension/sit-up assistance exercise. Exercise device will have rotatable rubber pegs attached to horizontal bars to aid in utility. Horizontal bars supporting hand grips will have apertures on its frame; apertures will take on the form of a T with arms going vertically down to engage device locking system. Horizontal bar with apertures will have tracks on top surface and bottom surface to support guidance of Hand grips. Horizontal bar with apertures will have a resistance element housed within, preferably but not limited to springs; also housed within bar will be spring caps with an protuberance attached that will make contact with Handgrips appendage to engage springs. Handgrips may have indentations to support lower back bar for lower back extension/sit-up assistance exercise. Device may have adjustable resistance.

An exercise system for use with tools having weighted masses includes a housing having an upper end and a lower end, and a strike post having an upper end that is located above the upper end of said housing and a lower end that is located between the upper and lower ends of the housing. The strike post is configured to move along a vertical axis that extends between the upper and lower ends of the housing. A shock absorbing pad overlies the upper end of the strike post. A spring assembly is disposed between the lower end of the strike post and the lower end of the housing. During a physical exercise session, the shock absorbing pad is hit with a toll having a weighted mass to apply an impact force, which is transferred through the strike post to the spring assembly for compressing the spring assembly.

The present invention relates to a hand gripper including a first arm, a second arm, a pair of spring members, a first spring member coupling shaft, and a second spring member coupling shaft, wherein a plurality of first elastic force adjusting grooves and a plurality of second elastic force adjusting grooves, to which the first spring member coupling shaft and the second spring member coupling shaft are selectively coupled, respectively, to adjust strength of elastic force provided by the spring members, are formed in a first body of the first arm and a second body of the second arm, respectively.

An elastic sound generating device, comprising an elastic sounding body integrally formed of an elastic material, the elastic sounding body having therein one or more sound amplified holes which can be pressed to adhere and then released to generate vibration and sound, and the sound amplified hole is opened through an outer surface of the elastic sounding body. The elastic sounding body is pressed and deformed until inner walls of the sound amplified hole adhere to each other, and then the elastic sounding body is released to restore the original shape and separate the inners wall of the sound amplified hole, and when the inner walls of the sound amplified hole are separated from each other, a sound is generated. The generated sound as a detectable signal is a solution for the range of motion of the training joint, the strength of the output and the shortest duration.
