A hand-held exercise weight system has integral self protective features within each weight system. Each weight system has an activation button located near the user's thumb. One (1) weight system is equipped with a loud audible alarm to signal for help in times of duress. The other weight system is equipped with an ultrasonic dog repellent system, which deters any possible attacking canines. Each weight system is provided with a user replaceable battery, and is self-contained and waterproof. Each weight system has a weighted body that is detachable from the system.

A locomotion system for use with a virtual environment technology includes a platform configured to support a user, a harness support assembly coupled to the platform and extending upwardly from the platform, and a safety harness configured to be worn by the user. The harness support assembly includes a support halo positioned above the platform and extending about a vertical central axis. The safety harness includes an interface structure moveably coupled to the support halo.

A virtual environment can use an absolute orientation framework. An absolute orientation framework in a virtual environment can be activated using an omnidirectional locomotion platform. An absolute orientation framework enables a user's avatar to move independently from the current viewpoint or camera position. The user's avatar can move in an absolute manner relative to a virtual environment map.

A treadmill belt guard includes a weighted cylindrical body, a first arm, a second arm, a first adaptor, a second adaptor, a first interlocking fastener, and a second interlocking fastener. The first arm is externally connected onto a lateral surface of the weighted cylindrical body. The second arm is externally connected onto the lateral surface of the weighted cylindrical body. The first arm and the second arm are positioned parallel to each other. The first adaptor is terminally mounted to the first arm through the first interlocking fastener. The first arm is positioned in between the first adaptor and the weighted cylindrical body. The second adaptor is terminally mounted to the second arm through the second interlocking fastener. The second arm is positioned in between the second adaptor and the weighted cylindrical body.

A system and method for range of motion analysis while exercising, including methods for constructing user movement profiles based on repeated and typical user movements during exercises as are typical for an adult of a user's age, weight, etc., and capable of warning a user of unhealthy, unsafe, or anomalous movement patterns during exercise, using a balance trainer, range of motion analyzer, and a plurality of sensors in conjunction with an exercise device, in an effort to reduce health risks to users during exercise with an enhanced or mixed reality exercise device.

A training method, training system and non-transitory computer-readable medium are provided in this disclosure. The training method includes the following operations: receiving a training script; wherein the training script includes at least one training stage corresponding to a timeline, and a training time and a training goal corresponding to the least one training stage; generating a voice information according to the training script, and outputting the voice information by an audio outputting unit; receiving a physiological signal sensed by a physiological signal sensor in the at least one training stage, and analyzing the physiological signal utilized an analyzing module to obtain an analysis result; and determining whether the analysis result meets the training goal corresponding to the at least one training stage; if not, outputting a voice reminding by the audio outputting unit.
