As an aside: The video of the bounceback has some of the most painful pseudo science I've seen in a while. Their references to motion and lymphatic system are purely wrong. Lymphatic circulation is a matter of rather more than changing vertical pressure, and is helped more simply by walking and swinging the arms naturally with core muscle support than by bouncing as demonstrated.
Which isn't to say that as an initial way to build muscle, the chair isn't good - but to be done effectively, that would require a more active torso and arm involvement. Which can be done simply by changing posture throughout the exercise set, working arms as well as legs, and so on.
