Patent ID: 7445585

Claim:
An inertial exerciser, comprising: a central axle, said central axle extending in a longitudinal direction defining an axis of rotation; a handle; a first pendulum rotatably mounted on said central axle, said first pendulum including a pendulum rod having a first end and a second end, said second end of said first pendulum rod including a first eyelet and a first eyelet hole therethrough configured to receive said central axle, said first eyelet defining a first plane, transverse to said axis of rotation; a first weight provided on said first end of said first pendulum rod, said first weight including a center of mass defining a second plane transverse to said axis of rotation and spaced from said first plane; a second pendulum rotatably mounted on said central axle, said second pendulum including a pendulum rod having a first end and a second end, said second end of said second pendulum rod including a second eyelet and a second eyelet hole therethrough configured to receive said central axle, said second eyelet defining a third plane, transverse to said axis of rotation; and a second weight provided on said first end of said second pendulum rod, said second weight including a center of mass defining a fourth plane transverse to said axis of rotation and spaced from said third plane; wherein the center of mass of said first weight and the center of mass of said second weight are aligned to oscillate in one plane; wherein said first weight is mounted on said first pendulum rod, and said second weight is mounted on said second pendulum rod; and said inertial exerciser further comprising: a plurality of attachment holes provided along said first end of said first pendulum rod; a mounting device to mount said first weight on said first pendulum rod via any one of said plurality of attachment holes along said first pendulum rod; a plurality of attachment holes provided along said first end of said second pendulum rod; and a mounting device to mount said second weight on said second pendulum rod via any one of said plurality of attachment holes along said second pendulum rod.
