Multi-purpose exercise device with synchronized sliding

Abstract

The present invention is a multi-purpose exercise device with synchronized sliding. It comprises a base and a pair of tracks disposed on it. Two slides including rollers are engaged on the same tracks. The rollers of the slides are engaged in the grooves of the tracks. Furthermore, the two slides are connected by resilient members, and each of the slides are coupled to three poles arranged in the shape of a triangle and at least two of said poles are pivotally mounted on pulley. Each of the elastic bands are engaged over the pulleys of the poles of each slide, allowing the two slides to be moved simultaneously from one end of the tracks to the other and providing more flexible exercise functions.

What is claimed is:
