A handgrip and leg brace assembly is located over a horizontal bench portion of a stretch bench that receives and supports a user's upper torso. The handgrip is adjustable in the horizontal and vertical planes as stretching exercises are on-going and without the user leaving the bench proper. Additional bench adjustments provide an individualized height setting, and these combined adjustments allow the bench to be personalized for each given individual in order to increase the effectiveness of certain on-the-bench stretching activities.
