Developed in Sweden by a group of decathletes, Flowin® is functional strength training without the use of weights. It essentially allows you to determine the level of your workout based on how much pressure or friction you place on a small set of pads – supported by your knees, elbows, feet or hands– that you slide horizontally, vertically, diagonally on top of a larger plate (a large vertical pad) – thus the name Flowin® Friction Training™.
