A weight-supporting user-encircling frame into which the user positions him/her self preparatory to lifting the frame with weights of a selected extent mounted thereon. The frame has vertically positionable hand grips that in their positions of movement effect the extent of the knee bend in the assumed lifting position of the user, thus obviating, for example, a deep knee bend which for medical reasons the user should not assume while weight-lifting.
