Barbell exercises are a type of strength training that involve the use of a barbell, which is a long metal bar with weights attached to each end. Two common barbell exercises are the CURL and the SQUAT. The CURL is an exercise that involves lifting the barbell up to the chest while keeping the elbows close to the body. The SQUAT is an exercise that involves lowering the body down into a squatting position while holding the barbell across the shoulders. Both exercises help to build strength and muscle mass.
