Patent ID: 7291098

Claim:
A method of adjusting weight resistance to exercise, comprising the steps of: positioning a first weight and a second weight in side-by-side alignment with one another to define a cylindrical cavity having at least four sectors, including an upwardly open first sector defined by within a platform of the first weight, an upwardly closed second sector defined within the platform of the first weight, an upwardly open third sector defined within a platform of the second weight, and an upwardly closed fourth sector defined within the planform of the second weight; positioning a liftable member relative to the first weight and the second weight in such a manner that a rotatable weight selector on the liftable member occupies the cavity; rotating the weight selector to occupy the first sector and the second sector and thereby secure only the first weight to the liftable member; rotating the weight selector to occupy the second sector and the third sector and thereby secure both the first weight and the second weight to the liftable member; rotating the weight selector to occupy the third sector and the fourth sector and thereby secure only the second weigh to the liftable member; and rotating the weight selector to occupy the fourth sector and the first sector and thereby release both the first weight and the second weight from the liftable member.
