InactiveUS20110281699A1Easy to receiveEasily indicate correct positionMuscle exercising devicesEngineeringMuscle stretching
A muscle stretching apparatus includes a flexible, essentially inextensible main support structure of elongate dimension. At least a pair of bilateral auxiliary support structures is carried on the main support structure, each provided as serially arranged segments along at least a portion of an overall length of the main support structure. Each of the segments is connected with the main support structure creating a loop defining a bounded opening between each segment of the auxiliary support structure and the main support structure, thereby forming a handle structure for engagement by a hand or other appendage. Optionally, at least one end of the muscle stretching apparatus terminates in a loop free of the centrally disposed main support structure, for facilitated reception of, for example, a foot therein. Tension applied between an anchored position of the apparatus and at least one grasped position is used to stretch a selected muscle or muscles.
