AI Technical Summary

Benefits of technology

The present invention is an adjustable dumbbell assembly designed to allow users to easily and quickly adjust the weight. The assembly also includes a structure that can be quickly actuated or controlled by the user. Additionally, the assembly has no extension carriers or tracks, which allows for a shorter total length.

Problems solved by technology

However, the extension carriers or tracks are required to be permanently formed or provided on the end portions of the central handle bar such that the extension carriers or tracks and the central handle bar may form and may include a greatly increased length for the typical adjustable dumbbells and such that the length of the typical adjustable dumbbells may not be suitably reduced or decreased.
