The invention concerns a mat system comprising a plurality of individual mats, each with a top side, a bottom side, and at least one rectilinear side edge. The rectilinear side edges each have at least one undercut recess, corresponding to connecting means which enable, by engagement of each one of their halves in an undercut recess, a connecting of two mats along their rectilinear side edges. The individual mats and the connecting means each comprise at least one layer of foam material. In order to equal out even large tolerances in the orienting of the individual mats to each other, the connecting means each comprise two interconnected circular segment regions with a radius R, R′, wherein for the spacing A of the centre points of the circular segment regions the following relation applies: (I) 0.8*(R+R′)<A<1.3*(R+R′).

A sand training bag for sand and/or mineral training in an open and closed configuration. The sand pit training bags includes a sand pit training bag configuration comprising at least one fastener and at least one overlaying fabric around the perimeter to open flat on a surface. The sand training bag includes attachable wall structure, wherein the surface attachable wall structure is configured with a sand pit training bag in an open configuration visible relative to a sand or mineral pit held by one or more fasteners. The sand training bag includes a single sand pit training bag, wherein the single sand pit training bag is convertible to a single sand pit with at least one attachable perimeter wall around the perimeter of the open sand or mineral receiving surface configuration, wherein a top cover is configured to be viewed as a sand or mineral pit closed configuration.

A method for providing pressure feedback is described herein. The method includes receiving, via a processor, pressure sensor data from a plurality of pressure sensors over a period of time. The method also includes receiving, via the processor, movement data from a plurality of sensors over the period of time. The method also further includes sending, via the processor, pressure sensor data and movement data to a data service. The method also includes receiving, via the processor, a feedback from data service.

A plyometric box for includes a platform, a first pair of opposed sidewalls, and a second pair of opposed sidewalls. Each sidewall extends downwardly from the platform, and includes a first side, an opposed second side, a first pair of stacking ribs on an interior surface of the sidewall proximate the first side, and a second pair of stacking ribs on an interior surface of the sidewall proximate the second side. Each stacking rib extends downwardly from the platform along the sidewall and a bottom surface of each stacking rib is spaced upwardly from a bottom edge of the sidewall.

Examples of a mat are disclosed. The mat comprises a body with a first surface and a second surface, and a microbial component that comprises pre-determined microorganisms which are dispersed in the body of the mat between the first and second surfaces, on one of the first surface or the second surface, or on both of the first surface and the second surface. The microbial component manipulates a microbiome of an environment adjacent or in contact to the mat. The microbial component can comprise at least one of live bacteria, bacteria endospores, fungi, viruses, protozoa, algae, slime moulds, archaea, micro-plants, a synthetic biology system or microbial precursor that stimulate growth of the desired microorganisms.
