Abstract

The invention provides a multi-angle Achilles tendon stretching pedaled trainer, including two arc-shaped rockers with one on the left and the other on the right. Besides, two pedals that can be stepped on by a user are provided on top of each rocker, with one on the front and the other on the rear. Also, an axle pole is provided between the two rockers for connection, allowing the two feet on the pedals to make forward and backward swaying motions in order to twist waist and hips, strengthen leg muscles and develop body balance.
