Product Description:
Jin BD wrist trainer ball is a new generation of stress relief tool and black technology on the palm.It adopts an artificial power device, purely mechanical design, no power supply, no electromagnetic radiation, and relies on the rotation of the wrist to drive the high-speed rotation of thewrist trainer ball, thereby generating strong centrifugal force, achieving the goal of strengthening your wrist. The first time a user wants to start it is extremely challenging, requiring you to patiently explore and pay attention to skills. Once you master the correct startup method, it will become easy to control, arbitrary, and full of fun.
Item Startup Method:
1. Wear a dedicated wrist strap to prevent the wrist
trainer ball from falling
2. The wrist trainer ball is facing upwards, with the
left and right thumbs pressing on the inner ball and
alternately pushing forward in the direction of the
inner ball arrow, until there is greater resistance to
the forward movement (until the inner ball is difficult
to continue rolling forward, about 10 times).
3. Release the inner ball with your thumb and hold it
with one hand, while quickly rotating your wrist (using
your wrist as a support point to perform rapid and
repeated circular movements). When the inner ball
rotates faster and the dazzling light comes on, the
wrist trainer ball has already started. If the start fails,
please repeat the above steps.
