A hurdle assist includes a flexible tubular lower section comprising a first length and a first slit along the first length, a flexible tubular upper section comprising a second length and a second slit along the second length, and a flexible rod which is slidably removably coupled with the flexible upper section. Attaching the hurdle assist to a hurdle mimics a flexible hurdle for the runner to practice without fear of injury.

A resettable breakaway apparatus may include: a housing having an aperture. A plunger may extend through the aperture, and the plunger may be movably coupled to the housing. The plunger may have a plunger head, and the plunger head may be movable between a first position, in which the plunger head is relatively farther from the housing, and a second position, in which the plunger head is relatively closer to the housing. A tensioner may tension or compress the plunger head in the first position. The apparatus may further include a receiver having a receiver head. The housing may be coupled to a first object and the receiver may be coupled to a second object, and the apparatus may be configured to removably couple the objects together by engaging the plunger head with the receiver head so that the plunger head may be positioned between the first and second position.

Device for training people to a preferred posture during normal gait comprising of: at least a base for stabilizing at least one rail or post coupled to said base at least one gait regulating component, which will be arranged perpendicularly with respect to said rod or post and parallel to the floor surface, with said gait regulating component provided for defining an obstacle during the normal gait of a user to impose on the latter a predetermined movement of the foot, knee, and hip, facilitating the maintenance of the user's bust erected in a position of equilibrium, with the consequent lengthening of the pushing leg, the gradual transition of the weight of the user's body by the supporting foot posterior to that of the advancing leg, and the oscillation of the arm forward opposite to the lower limb that moves, with a final effect of a steady pace.

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.

A training device includes a first leg, a second leg, and a top board connectable to the first leg and the second leg. The top board has a first position transverse to a path of travel between the first leg and the second leg providing a releaseable obstruction along the path of travel. The top board further includes a breakaway joint operable to release at least a portion of the top board to a second position on an impact to the top board thereby providing an open passageway through the top board along the path of travel.

A sport training structure includes a plurality of brackets and a plurality of first pivot members connected with the brackets. Each of the first pivot members has two connecting portions. Two of the first pivot members are mounted between two of the brackets to construct a polygonal frame, with each of the two connecting portions of each of the first pivot members being pivotally connected with one of the two pivot ends of each of the brackets. In such a manner, the two of the brackets are pivoted about the two of the first pivot members, so that the polygonal frame is foldable.

A hurdle structure includes a transverse bar, two upright poles, two support rods, and a plurality of hinge mechanisms. Each of the hinge mechanisms is mounted between the transverse bar and each of the two upright poles, and between each of the two upright poles and each of the two support rods. Each of the hinge mechanisms includes a first pivot member, and a second pivot member pivotally connected with the first pivot member. Each of the hinge mechanisms further includes an adjusting unit mounted between the first pivot member and the second pivot member. The adjusting unit includes a locking member and a positioning member. The locking member is provided with a plurality of grooves. The positioning member is provided with a projection positioned in one of the grooves of the locking member.

The present invention provides for a hurdle having an upright position and a collapsed position, the hurdle comprises a crossbar and a pair of legs pivotally connected to the crossbar. Each leg has a proximal end and a distal end where the proximal end is pivotally connected to the crossbar end and the distal end is for placement on an exercising surface. The distal ends of the legs can be rotated away from the bottom surface of the crossbar in an expanded upright position. In an upright position the hurdle provides height relative to the exercise surface which can be adjusted by a pivot angle between the crossbar and legs. When the hurdle is in a collapsed position the legs are substantially parallel to the crossbar. In another embodiment the crossbar of the hurdle can be used as a rung in an exercise agility ladder.

A huddle assembly is provided having a base, two upright members, and a cross bar extending between the two upright members. The cross bar includes a first bar member and a second bar member. An attachment member temporarily secures the two bar members together to form a continuous bar. The two bar members are pivotably supported on a respective upright member. The temporary attachment of the two bar members permits their separation upon contact by a runner. The pivotable attachment to the uprights permits the rotation of the bar members, during separation, about a vertical axis of the upright members.
