Background

The flat plate support (plank) is a muscle training method similar to push-up, but does not need to be pushed up and down, is mainly in a push-up posture during training, keeps balance when a body is in a first line, can effectively train the transverse abdominal muscles, and is known as an effective method for training a core muscle group. The exercise method comprises the steps of lying on the stomach, enabling the elbows to be supported on the ground in a bending mode, enabling the shoulders and the elbow joints to be perpendicular to the ground, stepping on the ground with the feet, enabling the body to leave the ground, enabling the trunk to be straightened, enabling the head, the shoulders, the crotch and the ankles to be kept on the same plane, tightening the abdominal muscles, tightening the pelvic floor muscles, lengthening the spine and enabling the eyes to look at the ground. When the training person does the flat support motion, usually go on yoga mat or level ground, the person of taking exercise can only keep above-mentioned conventional flat support posture to train, keeps a training posture always, makes the person of taking exercise dull and boring easily, has appeared on this market for this and increased the dull and stereotyped support auxiliary instrument of taste function when taking exercise.

For example, an abdominal and core exercise device of application publication No. CN109310909A, comprising: a support adapted to receive a person's arm or hand and adapted to receive a display device; a destabilizer connected with the support portion, the destabilizer including a pivot ball mounted to a trunnion ring; a fixed base adapted to hold the destabilizer. Make the supporting part can universal rotation through pivot ball at the fixed baseplate internal rotation, because be through the sliding connection of face and face between pivot ball and the fixed baseplate, exerciser's hand or elbow support on the supporting part, the most weight of human body all concentrates on the dull and stereotyped backup pad, under the condition of heavily pressing, face and face slip between pivot ball and the fixed baseplate are comparatively dry and astringent, and the feeling on the support part rotation feedback exerciser's hand or elbow is not very good, slides more smoothly between for making pivot ball and the fixed baseplate, need add emollient (lubricating oil or lubricating grease) to between pivot ball and the fixed baseplate, but the pivot ball can take out the emollient when rotating, makes the emollient volatilize, has not played fine lubricated effect.

For example, application publication number is CN 107007969A's a dull and stereotyped special balance plate of support that provides gravity induction training, the on-line screen storage device comprises a base, the base top has the bearing board through a universal seat structural connection, the bearing board top is provided with the elbow supporting pad that is used for the bearing elbow, be provided with the recess that is used for installing gravity induction system on the elbow supporting pad, the universal seat structure is the rzeppa universal joint. Rotation control bearing board through the rzeppa universal joint rotates to arbitrary direction, but each structural component of rzeppa universal joint is non-standard component, need support the size or the structure of special balance plate according to the flat board and improve the rzeppa universal joint, and need customize specially, then assemble each part of customization together, during the assembly, need aim at each raceway with the steel ball and fill in once, and need cup joint each part layer upon layer together, it is loaded down with trivial details to assemble, the opening of rzeppa universal joint is up, in the use, dust or grit can fall into the rzeppa universal joint, in case get into the foreign matter in the rzeppa universal joint, just cause the fast wearing and tearing of rzeppa universal joint during the use easily, and vibration and abnormal sound can appear, influence the user and use.
