Examples relate to a system to apply stimuli to a human body. The system comprises a three dimensional display, a stimulation element, a specific piece of clothing, a portable background and a controller. The controller comprises a processor, data storage and an instruction set. The instruction set is to cooperate with the processor, data storage, three dimensional display and stimulation element to display a recorded three dimensional representation of an actor in movement and to transmit to the stimulation element stimuli synchronized with the movement. The actor is wearing a piece of clothing having the same aspect as the specific piece of clothing, the actor being located in front of a background having the same aspect as the portable background, the recording being from the actor point of view.

A hula hoop, comprising a hoop body which includes a plurality of unit sections connected end to end, two adjacent unit sections are detachably connected to each other through a connecting member, and each unit section has an accommodating groove for inserting the connecting member. The front section and the rear section of the connecting member are inserted into the accommodating grooves of two adjacent unit sections, and the unit section has a locking mechanism for keeping the connecting member in the accommodating groove. The hoop body comprises a plurality of unit sections connected end to end. Two adjacent unit sections are connected to each other through a connecting member, which can realize the rapid disassembhly and assembly of the unit sections. By increasing or reducing the number of unit sections, the inner diameter of the hoop body can be changed to adapt to exercisers with different body shapes, and the hoop body can be opened at any position, which is more convenient to operate than the prior art.

A method of lowering the blood lactate concentration of subject in the need thereof includes the step of applying to the subject a pulsating magnetic field to the thyroid area of the subject.

A weighted exercise belt apparatus for improved fitness and health training includes a belt body extending from a left end to a right end. The left end and the right end have a first and second mating member, respectively. The first and second mating members are selectively engageable to secure the belt body around a user's waist with a medial portion covering the user's lower back. A plurality of primary weight bars is coupled to the belt body. A plurality of magnets is coupled to the medial portion of the belt body. Each of a plurality of pouches has a plurality of first engagement members. The first engagement members are selectively engageable with a plurality of second engagement members of the belt body.

The invention is an ergonomic support seat cushion, the top surface of which is uniquely shaped and which can be used for seated exercise, stretching and self-massage.

The cushion includes contours derived using the mathematical equations based in the Golden Ratio () and certain proportions based in the Rule of Thirds. The size of the support cushion can be varied proportionally to the size of the person. The width shape of the device comes in different versions, each maintaining Golden Curves and Rule of Thirds proportions. The wider versions of the cushion have holes for the two Sitz bones in the pelvis. The support seat cushions for males versus females have differences to account for dimorphism of the pelvis. The unique dimensional curvatures of the invention can be incorporated within devices that have seats.

The present disclosure relates to a hula hoop. The hula hoop includes a track assembly with a plurality of track units interconnected end-to-end and a slider provided with rollers. The track unit includes an outer track having a receiving channel located at a first end and a protruding portion located at a second end opposite to the first end, a pressing component configured to secure two adjacent track units, and an inner track for jointly defining a circular path with the outer track. The rollers of the slider are configured to slide along the circular path. The hula hoop of the present disclosure is easy to assemble and disassemble.
