A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

Methods and systems are presented for accepting inputs into a treadmill or other exercise equipment to control functions of the treadmill or exercise equipment. An exercise control system can receive gestures and other inputs. The exercise control system can also obtain information about the user of the exercise control system and information about the environment in which the exercise equipment is operating. Based on the input and the other information, the exercise control system can modify or improve the performance or execution of user interface and functions of the exercise equipment. The changes make the user interfaces and/or functions user-friendly and intuitive.

A stair stepping apparatus comprising: a plurality of stairs forming a treadmill or endless belt on which a user steps, wherein each stair comprises: a first link comprised of a major step portion joined to a minor riser portion by a rigid elbow, and a second link comprised of major riser portion joined to a minor step portion by a rigid elbow.

An ice skating training system including an ice skating training system to allow a user to train and practice ice skating skills. The ice skating training assembly includes a treadmill assembly and a harness assembly. The treadmill assembly includes a frame, a pair of side-support-bars, a pedestal, a computer, an electric-motor, a plurality of bearings, and an artificial ice assembly. The artificial ice assembly includes a plurality of artificial-ice-panels and a plurality of lateral-pins to provide the user with a continuous loop of an ice-like surface. In preferred embodiments each of the plurality of artificial-ice-panels are constructed of an ultra-high-molecular-weight polymer to provide increased longevity and durability during use and the plurality of lateral-pins are constructed of a steel alloy for durability and longevity. Each of the pair of side-support-bars provide the user with a structural member to grasp during use.

A treadmill includes an exercise deck, and a tread belt on the exercise deck having multiple slats. At least one slat of the multiple slats has a first rod end and a second rod end protruding from the slat. A first track is defined in a first side of the exercise deck and a second track is defined in a second side of the exercise deck. The first track receives and guides the first rod end, and the second track receives and guides the second rod end.

A curved manual treadmill for the physical exercises of a user, comprising: a frame extending along a longitudinal direction; a first rotation shaft adapted to rotate around a respective first rotation axis transversal to the longitudinal direction of the frame; a second rotation shaft adapted to rotate around a respective second rotation axis transversal to the longitudinal direction of the frame; a physical exercise surface operatively connected to the first rotation shaft and to the second rotation shaft, so as to generate an endless closed physical exercise path, and a device for resisting the movement of the upper portion of the physical exercise surface operatively associated with at least either the first rotation shaft or the second rotation shaft.

A treadmill has an exercise deck, and a tread belt disposed on the exercise deck. The treadmill further has a tensioning mechanism attached to the exercise deck, and the tensioning mechanism has a selectively movable structure movable with respect to the exercise deck to push outward against an inward surface of the tread belt.
