Explore the many elements of strength training and cardiovascular conditioning.
Fitness (or Physical Fitness) is a general state of health and well-being and, more specifically, the ability to perform aspects of sports or occupations. Fitness is generally achieved through correct nutrition, 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.
Fitness is defined as the quality of being suitable to perform a particular task. Regarding specific function, fitness is attributed to personnel who possess significant aerobic or anaerobic ability, e.g strength or endurance. A holistic definition of fitness is described by Greg Glassman in the CrossFit journal as an increased work capacity across broad times and modal domains; mastery of several attributes of fitness including strength, endurance, power, speed, balance and coordination and being able to improve the amount of work done in a given time with any of these domains. A well rounded fitness program will improve a person in all aspects of fitness, rather than one, such as only cardio/respiratory endurance or only weight training.
A comprehensive fitness program tailored to an individual typically focuses on one or more specific skills, and on age- or health-related needs such as bone health. Many sources also cite mental, social and emotional health as an important part of overall fitness. This is often presented in textbooks as a triangle made up of three points, which represent physical, emotional, and mental fitness. Physical fitness can also prevent or treat many chronic health conditions brought on by unhealthy lifestyle or aging. Working out can also help some people sleep better and possibly alleviate some mood disorders in certain individuals.
The U.S. Centers for Disease Control and Prevention encourages the adult public, ages 18 to 64, to engage each week in at least one and a quarter hours of vigorous-intensity aerobic activity or two and a half hours of moderate-intensity aerobic activity; that time can be met in any increments.
A pull-up is an upper-body compound pulling exercise. The pull-up is performed with a palms facing forward position. Conversely, a "chin-up" (alternately, but incorrectly identified as a "pull-up" position) is done with palms facing the exerciser.PERFORM CHALLENGE
