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, 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.

Meditation is a mental discipline by which the practitioner attempts to get beyond the reflexive, "thinking" mind into a deeper state of relaxation or awareness. Meditation is a component of many religions, and has been practiced since antiquity. It is also practiced outside religious traditions. Different meditative disciplines encompass a wide range of spiritual or psychophysical practices that may emphasize different goals—from achievement of a higher state of consciousness, to greater focus, creativity or self-awareness, or simply a more relaxed and peaceful frame of mind.
