What is the name of the fitness equipment with a fan under two ropes?

This kind of fitness equipment is called back flip stretcher.

The exerciser sits on the seat cushion, treads on the left and right pedals respectively, holds the handlebar with both hands and pulls it back hard, and then pulls the flywheel to do work through the handlebar and (two) elastic ropes in turn.

When no force is applied, the flywheel rotates reversely under the return elasticity of the disc spring, and then the lever is tightened by the elastic rope. Repeatedly, you can keep fit. In order to increase inertia, a fan connected to the flywheel is added to the fan tensioner of the rear air outlet.
