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. With the goal of preventing illness and promoting physical
fitness, practitioners perform various routines
comprising a number of different dance-like exercises. Formal aerobics classes
are divided into different levels of intensity and complexity. A well-balanced
aerobics class will have five components: warm-up (5-10 minutes), cardio
vascular conditioning (25-30 minutes), muscular strength and conditioning
(10-15 minutes), cool-down (5-8 minutes) and stretching and flexibility (5-8
minutes). Aerobics classes may allow participants to select their level of
participation according to their fitness level. Many gyms offer a variety of
aerobic classes. Each class is designed for a certain level of experience and
taught by a certified instructor with a specialty area related to their
particular class.
