Abstract: A timber expander and coupling system both expands at least one dimension of existing timbers and spans two existing, timbers. The timber system includes first and second parallel spaced continuous members. Each continuous member includes a first portion extending in a first direction parallel to a timber, and a second portion, extending from the first portion, in a second opposite direction. The first and second continuous members are held in spaced, parallel relationship by either a cross-member, or an expander timber disposed in an expander timber receiver region formed by the second portions of the first and second continuous members. The first portions of the first and second continuous members form a timber coupling region, for coupling to timbers and for expanding the dimension of an existing timber, or for coupling to and spanning the distance between at least two timbers.

Abstract: A coordinated movement exercise apparatus which provides coordinated and resistive exercise to a user includes a base section to which are coupled first and second pivotable members connected diagonally by a connecting member. The first and second pivotable members and the connecting member combine to form a "Z" shaped exerciser section which insured coordinated exercise movement by the user. At least one resistive member is coupled between the connecting member and one of the first and second pivotable members to provide resistance to motion when in use by the user. A seat is also included on the exercise apparatus as well as hand and foot gripping or engaging members.
