Many of us start the year with plans to take up exercise again, but find it hard to keep the momentum going month after month. The golden rule for anyone who wants to bring exercise back into their life is to gradually increase the level of intensity and make sure you practice regularly, while keeping in mind your age and physical condition. It's better to opt for moderate physical activity three to four times a week, alternating muscle-strengthening and cardio exercises (cycling, walking, running, etc.), rather than give it everything you've got just at the weekend.
Physical fitness is a general state of health and well-being and, more specifically, the ability to perform aspects of sports or occupations. Physical fitness is generally achieved through correct nutrition, moderate-vigorous physical activity, exercise and rest. It is a set of attributes or characteristics seen in people and which relate to the ability to perform a given set of physical activities.
