Flexibility- Defined as the ability to move your joints or muscles through their full range of motion. Your flexibility is determined by a number of factors including joint structure, age, activity level, body composition and strength of opposing muscle groups. This ability is one of the components of physical fitness and needed to perform day to day activities and enjoy an active lifestyle.
While muscle endurance is needed for your muscles to perform repetitive actions, aerobic (cardiorespiratory) endurance is needed to perform physical activity and sports. Specifically aerobic endurance is determined by the ability of your heart to move oxygenated blood through your body and to working muscles. People with little or no aerobic endurance tire quickly when performing simple daily tasks such as climbing a flight of stairs or playing with their children. Increase you aerobic endurance or stamina through regular exercise. As your fitness level increases you will have to intensify or vary your workout to gain the maximum benefit.
