ABSTRACT:
A weight lifting machine is provided with a readily adjustable stop bar for use in arresting the lowering of weights in use. The adjustment mechanism includes manually adjustable latches mounted at each end of the stop bar for engagement with passages formed in the upright frame members of the machine. These latches can be manually engaged by an operator standing in the weight lifting station and suitable slides are provided which cooperate between the stop bar and the upright members to maintain transverse alignment of the stop bar as it is moved vertically with respect to the upright members.
