Modular teaching aid for physical fitness training

Abstract

A modular teaching aid for physical fitness training includes: a base plate whose top side is provided with a functional area; and two assembly portions each provided at one or the other of the front and rear ends of the base plate. The functional area has a functional portion protruding from the top side of the base plate. By varying the functional area of the base plate, the teaching aid can be used to switch different terrain rapidly, without having to replace the entire teaching aid. The teaching aid allows easy assembly and switching of components, and the assembly portions at the two ends of the base plate enable extension by connecting with additional components so as to increase the variability of the teaching aid and the range of content that can be taught with it.
