Abstract: A stance guide and method of use are disclosed to help a user achieve and hold a number of stances hence providing corresponding health benefits to the user. The stance guide includes an adjustable foot engaging and an adjustable body engaging device, connected to each other with a frame, for guiding and engaging the user's feet and body while accommodating a range of user population. The foot engaging or the body engaging device can include a sensing and signaling device plus a timer to help the user achieve correct stances for a desired time duration. A display device can be included for displaying the stance images as a visual aid. A guard device can be included for reducing the risk of an accidental fall during practice. Specific designs of the stance guide are presented with health benefits of reducing excess urination, enhancing sleep quality and reducing body weight.

Abstract: A compact stance guide is disclosed to help the user achieve and hold a number of stances so that the holding of each stance provides a corresponding health benefit. The compact stance guide includes a foot engaging device, a body engaging device and a framing structure connected to the foot engaging device and the body engaging device. At least part of the foot engaging device, the body engaging device or the framing structure are objects in pre-existence and made for another purpose hence the thus formed stance guide becomes lower in cost and perceptually more compact in size. In a specific embodiment, the compact stance guide includes a separate feet board, two elbow-engaging members and an extensible balancing bar. The extensible balancing bar has two ends for engaging two opposing vertical surfaces of a preexisting object for support.
