EXERCISE MACHINE FOR PROVIDING WEIGHT LIFTING EXERCISES SIMILAR TO THOSE PROVIDED BY A FREE WEIGHT BARBELL

摘要

An exercise machine for performing barbell type free weight lifting exercises has a power cage or Smith press type frame, an elongated bar held on the frame in a substantially horizontal resting position, and an adjustable exercise mass assembly that allows a user to select an exercise weight from among a plurality of choices of different exercise weights provided by the exercise mass assembly. The exercise mass assembly is separate from the bar and any auxiliary weight plates carried on the bar. A cable and pulley system operatively connects the bar to a movable portion of the exercise mass assembly that provides the selected exercise weight. A powered actuator sets up the bar for performing a weight lifting exercise by lifting the movable portion of the exercise mass assembly up above a second portion of the exercise mass assembly that remains stationary during the particular weight lifting exercise.

主权项

1. A method of weight lifting, which comprises:
(a) providing an exercise bar that is long enough to be gripped and held by both hands of a user with the user's hands being spaced apart from each other along the bar; (b) providing an adjustable exercise mass assembly that permits a user to select an exercise weight from among a plurality of choices of different exercise weights provided by the exercise mass assembly; (c) operatively connecting the bar to the exercise mass assembly such that the user selected exercise weight is coupled to the bar for use by a user in performing at least one weight lifting exercise of the type in which the user presses or lifts upwardly on the bar to lift the exercise weight; (d) establishing for a particular user a range of motion for a particular weight lifting exercise of the type that can be performed using the bar, wherein the range of motion comprises a vertical distance corresponding to vertical travel of the bar between a top raised position and a bottom lowered position of the bar which positions are determined by the particular user for use in performing the particular weight lifting exercise; (e) setting up the bar for performing the particular weight lifting exercise by elevating a first portion of the exercise mass assembly that provides the selected exercise weight above a second portion of the exercise mass assembly that remains stationary during the particular weight lifting exercise by a vertical distance that is substantially equal to the vertical distance comprising the range of motion; and (f) performing multiple repetitions of the particular weight lifting exercise with each repetition comprising lowering and lifting of the bar by the user from the top raised position of the bar to the bottom lowered position of the bar and back to the top raised position of the bar.
