Exercise training device

Abstract

An exercise training device includes a first support portion defining a first side that supports a user and having a first coefficient of friction. The first support portion includes a second side located opposite the first side. The exercise training device includes a second support portion defining a third side that is attached to the second side of the first support portion, and a fourth side, located opposite the third side, that is in contact with the surface upon which the exercise training device is supported. The fourth side has a second coefficient of friction that is less than the first coefficient of friction. In response to a force applied by the user to the first side along a direction that is parallel to the first plane, the fourth side is moves with respect to the surface.
