<p>A weight lifting apparatus (1) of the free type allows a user to lift a barbell and to release it at any stage safe in the knowledge that it will not drop by any appreciable amount. The user presses against a handle on the barbell to keep a lock released and immediately when he stops pressing the handle, the lock moves to its default, locked state and the barbell is suspended. Guide spools (15) are used to gather the belts (11) under the action of a counter-weight bracket (18). The barbell is suspended by ratchet and pawl mechanism locks which prevent the spools (15) from rotating.</p> |
