a. respectively injecting non-Newtonian liquid into the two handles simultaneously under the condition that no external force is applied to the spiral spring until the spiral spring and the handles are fully filled with the non-Newtonian liquid;
b. and bending the spiral spring until the two ends of the spiral spring are contacted, taking away the redundant non-Newtonian liquid extruded by the bending deformation of the spiral spring, and closing the end cover.
10. Use of a portable, bi-directional force applying arm exerciser according to any one of claims 1-8, wherein the ready-made arm exerciser is used, comprising the steps of:
A. force is applied to the outer wall of one side of the upper reflux cavity of the handle, the bent and deformed spiral spring is opened outwards, the outer wall of the elastic material of the handle is deformed under stress and is attached to the reflux plate, and the non-Newtonian liquid passes through the buffer groove on the reflux plate and enters the spiral spring, so that the spiral spring is stressed and unfolded at a constant speed;
B. and applying force to the outer wall of the handle at one side of the arm strength storage cavity which is restored to a natural state, folding and bending the two ends of the spiral spring inwards, enabling the outer wall of the elastic material of the handle to deform under the stress to be attached to the storage plate, enabling the non-Newtonian liquid to be extruded into the handle storage cavity through the deformation of the spiral spring, keeping the bending shape of the spiral spring unchanged after the force application is stopped, and repeating the exercise steps until the force is applied to the outer wall of one side of the handle backflow cavity again.
