While researching personal sports training, I found a need for a solution to the skipping rope length adjust.
The existing ropes in the market come in several limited lengths, or with external and cumbersome tuning solutions.
The adjustable skipping rope has an internal threading mechanism, allowing the length of the rope to be adjusted by rotating the rope handle. Right - extends, left - shortens. Each handle can be shortened and extended 50 cm from the rope, so the user can adjust between 2 and 3 meters of rope as needed.
