NOVELTY - A subject performs isometric contraction exercises using exercise equipment with strain gauge in the presence of fitness trainer that is not assigned to any other subjects to produce exercise result. A mandatory recovery period for subject is imposed in which subject does not perform isometric contraction exercises. Performing isometric contraction exercises and imposing mandatory recovery period are repeated using new set of one or more exercise constraints that are refined based on exercise results of previous isometric contraction exercise work out session.    USE - For facilitating isometric contraction exercise regimen for improving health and fitness of subject.    ADVANTAGE - Increases strength of individual while minimizing the number of exercise-related injuries that subject may suffer in the process. Provides convenient scheduling and personal training in private setting, utilizes isometric contractions on solid state fitness equipment, and analyzes the exerciser's medical information so that the proper amount of muscle tissue recovery and development time are determined for each exerciser at every appointment. Length of recovery time is adjusted to the physiological needs of individual by providing for mandatory recovery time between exercise appointments and custom-tailoring. Prevents injuries and optimizes the body's ability to develop skeletal muscle due to use of mandatory recovery period. Provides convenient and effective exercise program for participants by utilizing isometric contraction model. Enables person to perform exercises by taking the relevant muscle groups to failure while the muscle groups are in fully contracted state due to use of solid state fitness equipment.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are the following:    (1) a computer program product for use in conjunction with a computer system;    (2) a computer system for facilitating an isometric contraction exercise regimen for a subject; and    (3) an exercise apparatus for facilitating an isometric contraction exercise regimen for a subject.    DESCRIPTION OF DRAWING(S) - The figure shows the block diagram of a method of providing exercisers with improved health and fitness through increased muscle strength that is achieved without the risk of injury.
