Abstract: A swim training device includes: (a) a platform having a top side and a bottom side, and extending longitudinally from a leading edge to a trailing edge and extending laterally from a left side to a right side; and (b) a hands pocket located on the top side of the platform and including a hands entry opening facing toward the trailing edge of the platform, wherein: (i) the hands pocket is constructed to receive a user's hands through the hands entry opening so that the user's hands are located in the hands pocket in a generally extended configuration; (ii) the hands pocket is constructed to hold the user's hands in place in the generally extended configuration against the top side of the platform; and (iii) the hands pocket is constructed to resist longitudinal and lateral movement of the user's hands relative to the platform when the user's hands are located within the hands pocket.
