Abstract

A system and method for providing an exercise program at a desired pace throughout each repetition and which applies resistance against a user'"'"'s efforts based upon user performance history and user demographics. A central controller stores user demographics and performance information, and provides this information as well as program criteria and evaluations to any of a plurality of exercise stations. The exercise stations each include a magnetic brake for producing the desired resistance levels. A central processor unit (CPU) controls the exercise program at each station. The initial brake resistance is established based upon user demographic information and initial user performance of an exercise. The brake resistance is represented by lights in an LED stack simulating weights which move up and down along a run in conformity with position of a movement arm which the user moves. A pacer light moving adjacent the LED weight stack guides the user at a desired pace throughout each repetition. User performance including rate and limb extension is monitored and resistance is changed during the exercise period as performance corresponds to selected criteria. The user'"'"'s performance is evaluated based on performance history and demographically-based criteria to provide coaching comments to the user and to propose changes to the exercise program. Selected educational and instructional material relevant to the particular user may also be provided. In addition, by monitoring user parameters such as weight and percent body fat, and in view of user demographic and performance information, diet control information may also be provided.

88. A method of defining and controlling an exercise program performed by a user in conjunction with a movement arm which is adapted to be contacted by a portion of a user'"'"'s body and to be moved in response to extension of a portion of the user'"'"'s body, the method comprising the steps of:

defining an extension range comprising an acceptable range of movement arm positions during a selected portion of a cycle of a given exercise;

determining whether movement arm position is within the extension range during the selected portion of the exercise cycle; and

advising the user when the movement arm position is not within the extension range during said selected portion of the exercise cycle.

89. A method of defining and controlling an exercise program as defined in claim 88 further comprising the steps of communicating user reinforcement information when the movement arm position is within the extension range during said selected portion of the exercise cycle.

90. A method of defining extension values for a user of an exercise program in an exercise station having a movement arm adapted to be contacted by a portion of the user'"'"'s body and to be moved in response to extension of a portion of the user'"'"'s body, the method comprising steps of:

positioning the movement arm at a desired starting location;

instructing the user to move the movement arm as far away from the user'"'"'s body as possible;

monitoring movement of the movement arm;

storing values representative of movement arm position at selected portion of the exercise cycle; and

selecting the stored value corresponding to the movement arm position most distant from the user'"'"'s body.

91. A method of defining extension values as defined in claim 90 further comprising the step of:

multiplying the selected value by a selected percentage factor to define a full extension value for the given user.

92. A method of defining and controlling an exercise program performed by a user on at least one exercise station having means to communicate program results of the user following a completed exercise session, the method comprising the steps of:

measuring the user'"'"'s weight;

storing the communicated program results for each exercise station, and said user weight;

obtaining and storing the user'"'"'s physical information and work activity;

analyzing the user'"'"'s exercise program to determine energy expended by the user during an exercise session;

determining the amount of energy expended by the user during future exercise sessions;

determining energy expended by the user during activities other than exercise sessions;

analyzing the user'"'"'s energy consumption and weight information to determine if the user is within acceptable range of a desired weight control plan; and

informing the user of deviations from said desired weight control plan.

93. A method of defining and controlling an exercise program as defined in claim 92 further comprising the step of suggesting diet plans to align the user'"'"'s energy consumption and weight information with the desired weight control program.

94. A method of defining and controlling an exercise program as defined in claim 93 wherein the step of suggesting diet plans comprises the step of suggesting individual meal plans.

95. An exercise apparatus, comprising:

a movement arm adapted to be contacted by a portion of a user'"'"'s body and to be moved therewith;

a resistance means coupled to the movement arm so as to apply resistance to the movement arm by the user; and

means for determining user limb full extension limits and representing the limit of full extension of the user'"'"'s limbs as a function of position of the movement arm.

96. The exercise apparatus of claim 95, wherein the resistance means is set at a minimal resistance level when user limb extension limits are determined.
