The definition of exercise is physical activity to develop or maintain fitness. In today's day and age the definition has expanded to many different outlets. One who would like to take up cardiovascular exercise should turn to running, while a person attempting to build muscle mass should try weight training. There are plenty of different spins on older exercises. For example, people who are interested in aerobics could try Tae-Bo.
Yoga is also a fabulous new way to increase flexibility.
Millions of people around the world have taken a great interest in Yoga not only for physical reasons but spiritual ones as well. Exercise is wonderful for both body and soul. Almost every aspect of a person improves with the adaptation of some sort of physical activity. People benefit their skin, muscles, and even increase bone mass density if resistance training is done. It is also well known that sleep is much more tranquil and serene after exercise.
