an adjustable elevation board configured to be adjustable in length and comprising a bottom end and a top end, wherein the adjustable elevation board protrudes from the base at the bottom end, wherein at least the bottom end is oriented on the base in between the seat cushion and the padded interface;

a padding connectable to at least the top of the elevation board; and

a cabling connected to the padded interface running from the padded interface to near the rear end of the base and configured to be pulled by the user.

2. The adjustable stretching system as claimed in claim 1 , further comprising a foot sling stretchably connected to the base near the front end and configured so that when a foot of the user is in the foot sling and the user pulls the cabling, the foot sling resists pulling by the user.
