It utilizes the largest muscle groups of the body.
Currently, one popular form of kickboxing is known as aerobic or cardiovascular (cardio) kickboxing , which combines elements of boxing, martial arts, and aerobics to provide overall physical conditioning and toning. Unlike other types of kickboxing, cardio kickboxing does not involve physical contact between competitors — it's a cardiovascular workout that's done because of its many benefits to the body.
Cardio kickboxing classes usually start with 10-15 minutes of warm-ups, which may include stretching and traditional exercises such as jumping jacks and push-ups, followed by a 30-minute kickboxing session that includes movements such as knee strikes, kicks, and punches. Some instructors may use equipment like punching bags or jump ropes.
After this, at least 5 minutes should be devoted to cooling down, followed by about 10 minutes of stretching and muscle conditioning. Stretching is really important because beginners can strain ("pull") their muscles, and slow, proper stretching helps relax muscles and prevent injury .
It is to be noted that kick boxing is a high intensity, high impact workout and not meant for beginners or people with back or cervical injuries. It focuses on reflexes, speed, agility, power and strength. It also works on the cardio vascular system and improves its endurance and strength. According to the American council on exercise an hours session of cardio kick boxing can burn up to 350 to 450 calories!!!
