The term "free weight" refers to any type of weight lifting equipment that is not attached to a machine or cable system. Synonyms for the word "free weight" include: dumbbell, barbell, kettlebell, plate weight, and resistance band. Dumbbells come in various sizes and can be used for a variety of exercises, including bicep curls, shoulder presses, and lunges. Barbells are longer and can be used for exercises such as squats, deadlifts, and bench presses.
