ABSTRACT:
A negative resistance weightlifting apparatus suitable for use with, among other things, a weight in the form of a separate barbell, in which means under the direct control of the user controllably produces a negative resistance effect by pressing down with an adjustable force on the weight as it is being lowered and preferably positively disengaging itself from the weight when the latter is being lifted, safety means being provided to adjustably limit the weight locations where such force can be applied and to automatically release the excess downward force when the weight has achieved a predetermined and adjustable lower position, all to produce weight lifting and lowering excercises of maximum efficiency and effectiveness while at the same time protecting the user against accidents and any unfortunate consequences arising from temporary physical weakening.
