Weight machines commonly use specialized sets of plates (called "weight stacks"), consisting of a set of rectangular plates mounted on rails. Through a cable and pulley system, the burden is transferred to the machine's user. By placing a pin in the stack that causes the cable to pull on each plate above the pin, the weight is selected.
These hooks allowed for the quick and easy loading and unloading of weight plates. The BUR Quick Change was patented in 1930 [8] and first offered for sale in 1938 for $60 ($930 in 2010 dollars). [9] 95 Pound Set – A standard/deluxe set offered via mail-order. [10] 100 Pound Set – A standard set offered via mail-order. [11]
Drop sets and the technique also go by the names breakdowns, burnouts, descending sets, triple-drops (when a total of three different weights are used), down the rack or running the rack (when using dumbbells), up the stack (because with a weight machine, the pin is moved up the stack of plates with each drop in weight), strip sets (when you ...
A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines (pulley, lever, wheel, incline) changes the mechanical advantage of the overall machine relative to the ...
100 pounds (45 kg) plates are fairly rare, typically only used in some of the powerlifting federations still using plate sets scaled in pounds, such as IPA, SPF and their affiliates. Black 50 kilograms (110 lb) polyurethane coated plates were introduced by Eleiko in International Paralympic Committee sanctioned London 2012 Paralympic Games.
Another key feature was the much easier change of weight. With barbells and dumbbells, lifting at different weights required either a set of bells with different fixed weights, or else adding and removing weight plates at both ends, a process which could take up to a minute.
