NOVELTY - The machine (100) has a hydraulic motor for generating hydraulic communication signals to move a left rod and a right rod together at a constant rate to raise/lower a bar (102) at the constant rate. The hydraulic motor is connected to a left cylinder and a right cylinder. The hydraulic motor, left and right cylinders, and the left and right rods are arranged to prevent the bar from moving in response to a person while pressing/pulling the bar so that strength training is achieved by pitting muscles of the person against the bar that is immovable by the muscles of the person.    USE - Strength training machine for assisting a person e.g. youth, adult, and elder person, to build strength, anaerobic endurance and size of skeletal muscles, through bar press, bar pull, squats, lunges, and calf raises.    ADVANTAGE - The machine allows the person to develop the anterior deltoids, serratus anterior, coracobrachialis, the triceps, pectoralis major muscle and supporting muscles by pushing up or pulling against the moving bar that is positioned directly above a chest of the person and through squats, lunges and calf raises. The machine allows the person to utilize the full force through full range of arm motion without any resistance from gravity or variable resistance from elastics/hydraulics. The machine enables providing weight training and resistance training that increases muscle strength by pitting the muscles against weight or force. The machine allows the person to engage in an effective strength-training workout in a safer and more convenient manner while saving time. The machine enables providing an effective cardiovascular workout by setting the rate of speed at which the bar can be raised and lowered that allows the person to move the bar more quickly when extracting force against the bar, thus increasing the person's heart rate, circulatory rate, and respiratory rates for burning the calories. The machine has more attractive appearance, and allows the person to lose weight and tone the muscles in the body. The machine eliminates the risks such as losing of balance and falling encountered by a weightlifter when holding the heavy bar bell, thus eliminating the risk of dropping the heavy weight while exercising, and hence preventing injuries and fatalities. The machine allows the individual to engage in a more consistent workout without changing weight plates while saving time during exercise.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for utilizing a machine to assist a person in strength training.
