A multi-axial unidirectional power transmission system includes a transmission unit and a resistance unit. The transmission unit includes a first main shaft and a transmission wheel provided on the first main shaft. The resistance unit includes a second main shaft and a damping wheel mounted on the second main shaft. The two transmission wheels and the damping wheel can be placed flat on the body since they are mounted on different main shafts, thereby making the whole plane of the multi-axis unidirectional power transmission system consistent, thus achieving the effects of space saving, convenient storage and convenient transportation.

A multipurpose exercise device having a base that rests on a support surface and a user platform upon which the user stands. The lower end of a perpendicular support post is mounted to the base to axially pivot thereon and the upper end of the post is pivotally mounted to the lower surface of the user platform. The user platform pivots with the support post in a horizontal plane parallel to the support surface and pivots on the support post in a vertical plane perpendicular to the horizontal support surface. Resistance elements are provided having one end mounted to the support post and the other end mounted to the base to control the velocity and angle of pivot of the user platform in the horizontal plane. Preferably, a plurality of resistance elements are provided having one end mounted to the base and the other end mounted to the user platform to control the velocity and angle of pivot of the user platform in the vertical plane. In use, the user stands on the user platform and performs exercise motions to propel the user platform to pivot in the horizontal plane and the vertical plane.

Snow ski training methods with an apparatus are provided, including a snow ski training apparatus having two elongated freely rotatable overlapping ski arms pivotally mounted to a single vertical pivot point shaft fixed at the point of overlap on a sliding pivotal point assembly. Each ski arm has a foot pad with laces configured to receive a foot of a user at the tail end of each ski arm. Disclosed methods include placing a left foot and right foot of a user atop respective foot pads, assuming a hip flexed position, extending the hip and knees of the user until the user achieves an elevated position, laterally maneuvering the user's body through the user's sagittal plane while in the elevated position and around the single pivot point assembly, tangentially moving the user's feet along a congruent and overlapping arc, and returning to another hip flexed position.

Disclosed apparatus include an active stroller entertainment system including an activity base system, attachable with a stroller chassis, to facilitate a physical activity for a child when the child is inside the stroller, and a protective support system configured to operatively couple with the activity base system to support the child during the physical activity. Embodiments include the activity base system and the protective support system detachably attached with a stroller chassis, at least in part to form an activity area, inside the stroller, sufficient to facilitate the physical activity when the child is inside the stroller, while operatively providing support to the child and protection from physical injury within the activity area during the physical activity. The activity area is configured by comprising equipment particularly related to the physical activity, with which the child can actively interact, to improve the child's physical activity skills.

A multipurpose exercise device for replicating exercise motions that has a base on a support surface and a user platform. One end of a support post is axially mounted to the base and the other end is pivotally mounted to the user platform. The platform pivots with the post in a horizontal plane parallel to the support surface and pivots in a vertical plane perpendicular to the support surface. Resistance elements, dampening elements and a linkage system are selectively mounted to the support post and the base to control the velocity and angle of pivot of the platform in the horizontal and vertical plane. Ski and snowboard modules may be mounted to the user platform. The user stands on the platform or modules and performs exercise motions to propel the platform in the horizontal plane and the vertical plane to replicate the exercise motions, e.g., skiing and snowboarding.
