Abstract: A weightlifting assistance device for mounting on a rack, where the device weightlifting assistance 10 can comprise a base, a connector, a top, fixation frames, a fixer or coupler to affix or couple the weightlifting assistance device to the rack, a locking gas spring, and one or more guides and corresponding bushing. The top, which can be movable, can be equipped with slidable inserted barbell holder fixed thereto via a dedicated lock or locks. The force exerted to the barbell holder can unlock previously stored mechanical energy within the locking gas spring and can enable the weightlifting assistance device to produce counterforce to the applied outer force.
