Abstract: An exercise machine and an associated method of exercising that isolates and exercises the anterior deltoid muscles. The exercise machine provides articulating arm elements that support contact surfaces near the biceps of a person who is exercising. To perform the exercise, a person places his/her biceps against the contact surfaces of the articulating arm elements and attempts to elevate their arms forward about their shoulders. The contact surfaces press against the bicep regions of the person's arms and resist the movement. Since the resistance force is applied directly to the upper arm, the exercise does not involve any muscles in the hand, wrist or lower arm. Nearly all of the action needed to perform the exercise is dedicated to the anterior deltoid muscle group. Thus, the anterior deltoid muscle group is isolated for the exercise routine.

Abstract: A safety mechanism for weightlifting devices checks the uncontrolled descent of weights and/or other structures. Using aligned or other slots, a pawl or dog is biased against the surface containing such slots. In order to operate the weightlifting device, the pawl or dog must be actively disengaged from the slots. Exercise can then occur. However, should the weightlifter's grip relax and release the release lever, the associated biasing system forces the engagement end of the dog into one of the aligned slots halting the further downward travel of the associated weights in supporting structures. An associated weightlifting device is disclosed having a latching mechanism enabling securement of the device in a lowered position.

Abstract: An exercise machine utilizes the inherent capabilities of human muscles to exert greater forces during eccentric functions than during concentric functions. The exercise machine comprises a leverage arm pivotally connected to a frame. A force station is at a first distance from the pivotal connection. During a concentric muscle function, a person lifts first weights on the leverage arm. At the end of the concentric muscle function, a spotter applies a small force to the leverage arm at a second distance greater than the first distance from the pivotal connection. The small force produces a magnified load at the force station that the person resists during an eccentric muscle function. The leverage arm may be adjustable relative to the floor. The weight of the leverage arm may be counterbalanced. Various embodiments of the exercise machine utilize the same principles of physics for exercising different muscles.

Abstract: An isolation exercise machine comprises two force stations and a connection mechanism that causes the force stations to rotate in opposite directions in response to applying forces to the force stations. The forces overcome first loads due to weights placed on exercise arms to which the force stations are joined. The force stations are located relative to a support that enables a person on the support to exercise selected pairs of muscles. A leverage arm is attached to the connection mechanism for rotating with one or the other force station. At the end of a concentric muscle function, a spotter applies a small force to the leverage arm. The applied force is converted by the connection mechanism into second loads at the force stations that the person resists during an eccentric muscle function. A counterweight arm and counterweight may be used to cancel out the weight of the leverage arm.

Abstract: An exercise machine and an associated method of exercising that isolates and exercises the anterior deltoid muscles. The exercise machine provides articulating arm elements that support contact surfaces near the biceps of a person who is exercising. To perform the exercise, a person places his/her biceps against the contact surfaces of the articulating arm elements and attempts to elevate their arms forward about their shoulders.

Abstract: An exercise machine for performing squat exercises is provided for. The exercise machine comprises a support frame with a shaft horizontally mounted on the frame for rotation about its longitudinal axis. There is at least one weight arm connected to the shaft. The weight arm is adapted to carry a weight at a point distant from the connection between the weight arm and the rotating shaft. Thus, the weight arm provides resistance and load as the shaft rotates. The novel squat machines also comprise a work arm that is connected to the shaft such that actuation of the work arm causes the shaft to rotate. A yoke is connected to the work arm. The yoke is adapted to accommodate the shoulders of an exerciser such that the exerciser is able to provide upward force on the work arm in opposition to the resistance of the weight arm by performing a squat exercise. When the exerciser performs the squat, the work arm causes the shaft to rotate and the weight arm to travel along an arcuate path.
