The basic piece of equipment for weight training and bodybuilding is a barbell. You will find the terminology for various components of a barbell illustrated below:

Exercise barbells are the simplest form, and they can be either adjustable (with the weights added or subtracted to change the poundage, or weight, on the bar) or fixed (with the weights either welded or bolted semi-permanently in place). Home gym barbells are usually adjustable, while the barbells in a commercial gym are normally fixed, with a separate bar for each 5-pound weight increment from about 20 pounds to over 200 pounds.

The second type of barbell, called an Olympic barbell, is used for heavy bodybuilding exercises, as well as for use in weightlifting and powerlifting meets. The length and weight of this barbell are standardized internationally.  An unloaded Olympic bar weighs either 20 kilograms (44 ½ pounds) or 45 pounds. The collars weigh either 2 ½ kilograms (5 ½ pounds) or 5 pounds.

Barbells are constructed around a steel bar about one inch thick and four to six feet long. Normally the bar with collars weighs about 5 pounds per foot. Its weight should be figured in when you are loading up the barbell for an exercise with specific poundage. (A five – foot bar with two 10-pound plates on each side, for example, would weight a total of 65 pounds.)

A tubular sleeve is often slipped over the bar to provide more freedom of bar movement in upper-body exercises. Crosshatched grooves called knurling are normally cut into the sleeve to provide you with a more secure grip on the barbell when your hands are sweaty. If the barbell you are using, does not have a sleeve, the knurling is usually cut right into the bar itself.

Clamps called collars hold metal (or vinyl covered concrete) discs called plates in place on the bar for an exercise. Inside collars are bolted to the bar with set screws to keep the plates from sliding inward toward your hands. Outside collars are fitted over the bar to hold the plates on the bar, keeping them from sliding off the ends during an exercise.

Dumbbells are merely shorter versions of a barbell intended for use on one hand or, most commonly, one in each hand. While barbells are used to work both the upper and lower body, dumbbells are usually intended for upper-body movements, particularly exercises for the arms, shoulders, and chest muscles. Dumbbell, bars are usually 10-16 inches in length. You can count the dumbbell bar and collars as five pounds when loading up the correct poundage for each exercise.
