Aerobic exercise, also known as cardio or endurance activity, is the cornerstone of most fitness training prog rams. Aerobic exercise causes you to breathe faster and more deeply, which maximizes the amount of oxygen in your blood. The better your aerobic fitness, the more efficiently your heart, lungs and blood vessels transport oxygen throughout your body.
Muscular fitness is another key component of a fitness training prog ram. Strength training at least twice a week can help you increase bone strength and muscular fitness. It can also help you maintain musclemass during a weight-loss program.
The muscles in your abdomen, lower back and pelvis — known as your core muscles — help protect your back and connect upper and lower body movements. Core strength is a key element of a well-rounded fitness training program. Core exercises help train your muscles to brace the spine and enable you to use your upper and lower body muscles more effectively.
Older adults in particular should include exercises to maintain or improve balance in their routine exercises. This is important because balance tends to deteriorate with age, which can lead to falls and fractures. However, anyone can benefit from balance training, as it can help stabilize your core muscles.
Flexibility and Stretching:
Flexibility is an important part of physical fitness. Stretching exercises are effective in increasing flexibility, and thereby can allow people to more easily do activities that require greater flexibility. Stretching also improves the rang e of motion of your joints and promotes better posture.
