A pushup exerciser includes a supporting board formed of a pair of joined board sections each defining an upper surface having a plurality of post receptacles formed therein. The post receptacles are arranged in pairs with each pair suitably spaced for receiving attachment posts of a handle unit. Each post receptacle pair includes a color indicia. The color indicia are selectively colored to provide association between handle unit positions in accordance with a selected theme such as muscle group emphasis. A pair of handle units suitable for gripping during pushup exercise are locatable and attachable to the board surface at positions and angular orientations defined by the post receptacle pairs.
