PHYSICAL FITNESS 3 ASPECTS: Aerobic exercise Flexibility Strength Training
A successful aerobic exercise program involves frequent physical activity that is rhythmic, repetitive, challenges the circulatory system, and uses large muscles. The exercise program must significantly increase the blood flow to the muscles for an extended period of time, promoting cardiovascular fitness. Such exercises are called isotonic, dynamic, or aerobic. If you want to have a healthy heart, you need to perform aerobic exercise.
Flexibility is an important component of a well-rounded fitness program. Most individuals tend to become tight and stiff with age. It is important to maintain normal flexibility for several reasons. Good flexibility reduces the probability that you will suffer from back pain and other postural types of pain syndromes. Normal flexibility also allows you to attain normal movement patterns in all activities and requires you to expend less energy as you go through your daily activities.
Many people don't realize the numerous benefits of a sound strength training program: increases in muscle size (if desired) and tone; increased muscle, tendon, bone, and ligament strength; increased physical performance and appearance; improved metabolic efficiency; and decreased risk of injury.
