An exerciser including a movable body carriage mounted on an exerciser frame for movement along tracks provided by the frame. A resilient foot engaging assembly extends from the exerciser frame. The resilient foot engaging assembly is adapted to be engaged by the user's feet to absorb the energy of movement in a first direction and to provide the user with a bouncing movement, which the user may translate into a movement of the movable body carriage in the opposite direction. The resilient foot engaging assembly may be provided as an attachment and retrofitted to existing exercisers. The resilient foot engaging assembly includes a unit mounting frame assembly and an independent usable exercising unit, such as an inflated dome or trampoline unit, removably secured thereon. The exerciser may include a resilient resistance system coupled to the movable body carriage and a set of pull lines with user grips trained over pulleys carried by the exerciser frame. Also disclosed are methods for enabling users to exercise in either one of two different modes.

A hurdle system and method. The hurdle system has a telescoping interior arm and a non-telescoping exterior arm. The telescoping interior arm has spaced-apart cylindrical apertures that allow the height of the telescoping interior arm to be locked. A hurdle cross bar support fixedly attaches to a distal end of the telescoping interior arm. A hurdle cross bar is supported by the hurdle cross bar support in a parallel relationship. A bottom cross bar is placeable on the ground as support base for the hurdle. A proximal end of the non-telescoping exterior arm and the bottom cross bar are fixedly attached. A pair of bottom cross bar extensions extend from opposite ends of the bottom cross bar to provide additional stability. A position adjustable counterweight at the bottom cross bar maintains the hurdle in an upright position.

The invention pertains to a method of detecting and calculating height of a jump performed by an individual, comprising the following steps:

A detection of a reception subsequent to the jump, this step comprising a sub-step of detecting a pressure spike of amplitude greater than a first threshold amplitude, within pressure measurements provided by a pressure sensor embedded aboard a watch worn on the wrist of the individual,

A calculation of a height of the jump by differencing a starting altitude corresponding to a last stable pressure measured before the pressure spike and a finishing altitude corresponding to a first stable pressure measured after the pressure spike via the pressure sensor, a stable pressure being defined as a pressure whose variations do not exceed 0.1 hectopascals for at least 2 seconds.

Example embodiments relate to a system, method, apparatus, and computer readable media configured to generate a multiple renditions of a user interface that is updated based upon athletic movements of two or more users remotely located from each other. The UI may be configured to simultaneously display energy expenditure values in real-time. In further embodiments, a joint energy expenditure values determined from multiple remote users may be simultaneously displayed.
