A barbell is a piece of exercise equipment used in weight training, bodybuilding, weightlifting, powerlifting and strongman, consisting of a long bar, usually with weights attached at each end. Barbells range in length from 1.2 metres (4 ft) to above 2.4 metres (8 ft), although bars longer than 2.2 metres (7.2 ft) are used primarily by ...
BUR did not manufacture Olympic bars or Olympic-sized plates. The original BUR-BEL plates had a center hole diameter of 1-1/4" and were designed to fit a 1-1/16" bar. Sometime in the 1950s, the bar diameter was reduced to 1" and the plates were drilled with a 1-1/16" hole. During its 38 years of operation, BUR Barbell offered the following ...
Olympic weightlifting uses a steel bar (also known as a barbell) with larger-diameter rotating sleeves on either end, holding rubber-coated weight plates of different weights. This sleeve rotation is important for the Olympic lifts, particularly the snatch and clean movements, because it drastically reduces the rotational inertia of the bar.
With relatively light weights (as in the "power snatch") locking of the arms may not require rebending the knees. However, as performed in contests, the weight is always heavy enough to demand that the lifter receive the bar in a squatting position, while at the same time flipping the weight so it moves in an arc directly overhead to locked ...
The constrained movement of the bar also reduces the role that stabilizing muscles play versus an exercise using free weights. This may allow heavier weights to be lifted, at the expense of engaging less muscle mass overall. It is also hard to keep an accurate training log because manufacturers do not usually indicate bar weights. [6]
