Stretch machine with adjustment features

Abstract

A stretch machine has a seat assembly that is coupled to a seat rail and is adjustable along the seat rail to accommodate people of different sizes. The seat assembly has a knee and a back cushion and can pivot with respect to the seat rail to perform stretching exercises. A person may sit on the back support and extend one or more limbs to the handlebar assembly and then rotate the seat assembly to stretch. A front support extends up to a handlebar assembly that has a front and a back handlebar. A standing stretch board is attached to the front support and can be adjusted along the front support to change the incline angle of the standing stretch board.
