The transmission assembly is provided in the device main body, the rope winding shaft is rotatably connected to the transmission assembly, at least one continuous rope winding spiral groove is provided along the peripheral edge of the outer wall of the rope winding shaft, the rope winding spiral groove has an inner end close to the transmission assembly and an outer end remote from the transmission assembly, and the oscillating piece is provided in the device main body in such a manner that the oscillating shaft around which the oscillating piece oscillates is collinear with the rotation axis of the rope winding shaft.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.

A load sensor includes a bolt configured to support a pulley of a weight machine, and a strain gauge laminated onto an exterior surface of a shoulder section of the bolt.

A weight resistance exercise apparatus for the external and internal muscles of the shoulder having a multiple plane unit with a rotating axis armature for exercise in intervening planes, a primary armature, a secondary armature connected at a proximate end to the primary armature and a plurality of mode selection disks disposed on the secondary armature.

A weight training device for a smart training system is described. The device may include a handle. The device also includes a resistance member coupled to the handle and configured to resist a motion of the handle. The device also includes a sensor coupled between the handle and the resistance member and configured to collect sensor data. The sensor data may include a degree of force applied to the handle. The device also includes a communication interface configured to transmit the sensor data to a remote computing device.

Smart weight training systems and methods are described. An example method includes receiving sensor data from a sensor disposed in a weight lifting device, and determining, by a processing device, one or more exercise characteristics based on the sensor data. The one or more exercise characteristics can include a power exerted by a user of the weight lifting device. The exercise characteristics can be displayed on a user interface display or recorded to a storage device.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.

Exosuit systems and methods according to various embodiments are described herein. The exosuit system can be a suit that is worn by a wearer on the outside of his or her body. It may be worn under the wearer's normal clothing, over their clothing, between layers of clothing, or may be the wearer's primary clothing itself. The exosuit may be assistive, as it physically assists the wearer in performing particular activities, or can provide other functionality such as communication to the wearer through physical expressions to the body, engagement of the environment, or capturing of information from the wearer.

An exercise cycle includes a crankshaft, cranks mounted to the crankshaft, a drive mechanism including a ferromagnetic flywheel that rotates in response to rotation of the crankshaft, and a non-contact force adjustment mechanism with which a force required to rotate the flywheel can be adjusted, the force adjustment mechanism including a pivotable member to which magnets are mounted, wherein the magnets can be moved closer to the flywheel when the pivotable member is pivoted toward the flywheel to increase the force required to rotate the flywheel and can be moved farther away from the flywheel when the pivotable member is pivoted away from the flywheel to decrease the force required to rotate the flywheel.

A weight arm assembly for use with a weight lifting rack is provided, the weight arm assembly including a mounting bracket configured to be attached to a vertical surface in a fixed position, an arm mount configured to be coupled to the mounting bracket so as to be pivotable about a first axis, a stop member coupled to the arm mount and configured to move between an engaged position to prevent pivoting of the arm mount through interaction with the mounting bracket, and a disengaged position to allow pivoting of the arm mount, and a weight arm configured to be coupled to the arm mount, proximate a first end of the weight arm, so as to be pivotable about a second axis substantially orthogonal to the first axis.
