Strength training station

Abstract

A strength training station having a shell, a resistance mechanism, and a tension band. The resistance mechanism is in the shell, one end of the tension band is connected to the resistance mechanism and the other end extends out of the shell. A metal support plate for stepping on is at the top of the shell, and the resistance mechanism is fixed at the bottom of the metal support plate. During exercise, a user steps on the metal support plate and pulls the tension band. The metal support plate is firm and less prone to deformation, and can reliably support user's weight. As a main stressed component, the resistance mechanism can bear large force. The resistance mechanism fixed on the metal support plate provides higher support strength to ensure reliable and stable operation of the resistance mechanism.
