Abstract

Abstract A home/travel exerciser comprises an elastomeric cord having a grip adjustably attached to each end thereof. An anchor strap is adjustably mounted on the cord, between the grips, for insertion between a door jamb and a door to hold the exerciser in a fixed position when the door is closed. Foot straps may be attached to the grips and a belt can be releasably attached to the grips to adapt the exerciser for various exercises.
