Patent ID: 7041041

Claim:
A handheld exercise device comprising, a) a first set of two resilient members each member having a midpoint and two ends, where the resiliency of each member in the first set is matched; b) a second set of two resilient members each having a midpoint and two ends, where the resiliency of each member in the second set is matched and of greater resiliency than the members of the first set; c) a releasable connector located on each end of each member in the first and second sets; d) a block enclosing the members so that the members can flex about the block when force is exerted on both ends of each member in at least one set of members; e) two straps that are releasably connected to at least the four ends of at least two members from the first or second set, where the two straps are of fixed and equal length and where the releasable connection to the members prevents the straps from being adjusted lengthwise; and where the exercise device is designed and constructed to be handheld and portable such that an individual can hold and operate the device without requiring any other support means for the device.
