A stretching device that enables a user to employ the mechanical advantage of a multi-pulley system while performing various, prolonged muscle stretches; the stretching device including a first anchor assembly, a second anchor assembly, and a motion transfer line. The first motion transfer line has a first anchor body and a first motion transfer pulley; the first anchor body being attached to the user and the first motion transfer pulley being coupled to the first anchor body. Similarly, the second motion transfer line has a second anchor body and a second motion transfer pulley; the second anchor body being attached to a stationary object and the second motion transfer pulley being coupled to the second anchor body. The motion transfer line is terminally attached to the first anchor body and is trained around both the first motion transfer pulley and the second motion transfer pulley.

A treadmill including a frame, an exercise deck attached to the frame, and a first push-up handle attached to the frame and elevated over the exercise deck.

Handles for use in exercise apparatus and in lifting apparatus are provided.

A body weight exercise device includes a frame, a first handle attached to the frame, a second handle attached to the frame, and a processor and memory. The memory includes programmed instructions to cause the processor to determine a characteristic associated with a performance of an exercise with the body weight exercise device.

An exercise apparatus includes a first cord, a second cord, and an adjustment mechanism. The first cord is pullable from and retractable around a first pulley. The second cord is pullable from and retractable around a second pulley. The adjustment mechanism allows for adjusting a pull-out tension provided by the first cord independently of a retraction tension provided by the first cord. The pull-out tension provided by the first cord is a tension provided by the first cord when the first cord is pulled from the first pulley. The retraction tension provided by the first cord is a tension provided by the first cord when the first cord is retracted around the first pulley.

An isolation bar for a chin-up or pull-up bar extends parallel or at an acute angle (angled facing upwards) and is below a grasping region of the chin-up or pull-up device. The isolation bar can be hung from the chin-up or pull-up bar by way of cables/elongated straps or be fixed to a door frame, wall mounted, or free standing device with the grasping region. In use, the forearms of a user are pushed against the isolation bar while carrying out a chin-up or pull-up.

A joint rotational exercise and stretching tool for strengthening muscles and connective tissues, particularly for shoulder internal and external rotation, with further applicability to the wrist, elbow, and hip. The device includes a mount, torque-generating mechanism, and ergonomic lever arm configured to align with anatomical joint axes. It enables concentric, eccentric, isometric, and passive modes of use. Unlike traditional tools that provide linear resistance or partial-range torque, this invention delivers continuous rotational resistance across the full arc of motion. Configurable mounting and ergonomic adjustments allow use across various joints, limb lengths, and exercise positions. Suitable for rehabilitation, injury prevention, and performance training in clinical, home, or athletic environments.

An exercise device including a fixing rod, a fixing hook, a connecting member, a first gripping member, and a second gripping member. The fixing rod and the second gripping member are disposed at two ends of the connecting member respectively. The first gripping member is mounted on the connecting member, and the first gripping member is selectively switchable between an extended position and a offset position. When the user grips the first gripping member, the first gripping member is at the extended position for the user to grip. When the user grips the second gripping member, the first gripping member is in the offset position to avoid the first gripping member interfering with an exercise process of the user, providing the user with a better use experience and safety.
