Abstract: A portable exercise device that is usable in the home by attachment to supporting structure. The device comprises a pair of bases that are configured for attachment to a support, a member having a peripheral edge being pivotally attached to one of the bases and a bar being pivotally attached to the other base. One end of the bar is attached to the base to which the member is attached by a resistance mechanism. To the other end of the bar is attached a strap that engages a portion of the peripheral edge of the member and extends therefrom for attachment to a grip. This structure reduces the resistance force produced by the resistance mechanism as the exerciser approaches full contraction of the muscle group being exercised to ensure a completely full contraction is made. The device also compensates for the use of a non-linear resistance mechanism. In addition the resistance provided by the device is easily adjustable, providing the appropriate resistance for the particular muscle group being exercised.
