Aerobics vs. Calisthenics — What's the Difference?

Aerobics is a form of physical exercise that combines rhythmic aerobic exercise with stretching and strength training routines with the goal of improving all elements of fitness (flexibility, muscular strength, and cardio-vascular fitness). It is usually performed to music and may be practiced in a group setting led by an instructor (fitness professional), although it can be done solo and without musical accompaniment.

Calisthenics (American English) or callisthenics (British English) (/ˌkælɪsˈθɛnɪks/) is a form of strength training consisting of a variety of movements that exercise large muscle groups (gross motor movements), such as standing, grasping, pushing, etc. These exercises are often performed rhythmically and with minimal equipment, as bodyweight exercises.

A system of physical conditioning designed to enhance circulatory and respiratory efficiency that involves vigorous sustained exercise, such as jogging, swimming, or cycling.
