Exerciser

An exerciser comprising

• a stretchable tension member, the length of said stretchable tension member being variable as desired in order to vary the force resistance of said exerciser,
• a length adjustor mechanism to which said flexible tension member is connected at one end, said length adjustor mechanism including
• a housing having a cavity therein, said cavity being open through an access port to atmosphere, and said housing having opposed side walls,
• a pin slideable along an axis between a release position and a lock position within said cavity, said pin extending at each end through a slot in one of said side walls, a loop of said stretchable tension member being received in said cavity around said pin through said access port, the length of one end of said stretchable tension member being adjustable at said release position by pulling said flexible tension member around said pin and the length of that one end of said stretchable tension member being fixed at said lock position,
• a roller rotatably carried on said pin, said roller being in direct contact with said stretchable tension member during use, and
• one finger plate fixed to said pin at each end thereof, both finger plates being exposed for use in moving said pin from said lock position to said release position, said finger plates, pin and housing being sized so that the fingers on one of a user's hands can grip said pin therebetween to hold same in the release position while the other of the user's hands is pulling said flexible tension member around said pin, and
• a handle connected to said length adjustor mechanism by which said stretchable tension member can be stretched as desired by a user.
