A multi-directional expandable modular agility exercise ladder has spaced rows of two part paired rungs having overlapping ends joined to each by a pivot post forming a variable angle chevron prow. Outer ends of the paired rungs are interlocked to two parallel spaced bands to complete the ladder. A hook and loop pad interlock is used. Alternately, spaced key holes extend through the bands with the outer ends of the rungs having downwardly extending retainer poles secured in a respective key hole. Alternately, releasable spring clamps hand movable along the band length secure rung ends to the bands.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

[Problem to be Solved] The present invention provides a recommended running pace calculation system and the like capable of calculating a recommended running pace that is recommended to a runner to be evaluated in a distance running.

[Solution] A recommended running pace calculation system 100 according to the present invention includes a correlation storage device 21 in which a first correlation is stored, the first correlation including correlations between running distances run by unspecified runners and their fastest running paces, a running pace acquisition device 11 configured to acquire running paces for predetermined sections in a distance running run by a runner to be evaluated, the distance running having a predetermined length, a correction device 22 configured to extract a fastest running pace of the running paces of the runner to be evaluated for the predetermined sections, and to correct the running paces of the runner to be evaluated for the predetermined sections based on the extracted fastest running pace and the first correlation, and a recommended running pace calculation device 23 configured to calculate a recommended running pace in a distance running recommended to the runner to be evaluated based on the corrected running paces of the runner to be evaluated for the predetermined sections.

A constant resistance exercise machine for sprint training or adaptation into exercise equipment having cyclical movements, preferably over a distance. The constant resistance exercise machine includes an exercise cable storage and feed reel, a constant tension spring motor, a resistance generating assembly, a flywheel, and an exercise cable. The constant tension spring motor is in operational communication with the exercise cable reel. The flywheel obtains a rotational resistance from the resistance generating assembly. The flywheel is in unidirectional rotational communication with the exercise cable reel via a one-way clutch bearing. The exercise cable is coiled about the exercise cable reel. The exercise cable is of a length that enables complete extraction of the cable from the exercise cable storage and feed reel and wherein the constant tension spring motor is arranged to retract a partially or completely extracted cable back onto the exercise cable reel.

The present invention relates to an agility ladder that possess raised rungs, allowing users to not only exercise their stamina and agility, but also increase the strength of their calf muscles and related lower leg muscular structure.
