Equipment:
There are basically two types of equipment that you will find in the gym - free weights and machines.
Free WeightsFree weights are the most basic form of bodybuilding equipment. The reason they are called "free weights" is because there are no attached pulleys, cables, pins, or weight stacks. They consist of barbells, dumbbells, and weight plates.
The Barbell :
The barbell is a long iron bar that is between 4 and 7 feet long on which weight plates and placed. Barbell exercises are performed by holding the barbell with both hands.At the top of the list are Olympic barbells. They are 7 feet long and weigh 45 lbs. These are heavy-duty bars that can handle huge weight loads of over 800 lbs. Some Olympic bars can handle weight loads of over 1000 lbs. Because they are so big they are used mostly for heavy basic exercises such as bench press, squats, and dead lifts.There are smaller versions of the Olympic barbell that are between 4-6 feet long. These bars are generally used for smaller exercises such as barbell curls, shoulder presses, bent rows, etc...
Many gyms also have a barbell rack that has an assortment of fixed weight barbells. They usually have barbells that are from 20 - 100 lbs. in increments of 5-10 lbs. (i.e. a 20 lb. bar, 30 lb. bar, 40 lb. bar, etc...).
Besides Olympic barbells, there are standard barbells. These are the types of barbells that you will see for sale in most department stores. They are 1 inch thick and usually 5-6 feet long. These are ideal for a home gym setting.
Dumbbells:
A dumbbell is a short barbell, usually 10 - 15 inches long. Dumbbell exercises are performed with a dumbbell in each hand. Most gyms have a dumbbell rack that has an assortment of fixed weight dumbbells. They usually have dumbbells from 5 lbs. - 100+ lbs. in increments of 5 lbs.
