What are the 4 variables of fitness and their definitions?

Exercise itself, volume, intensity and density are the only things that can be manipulated in a program. All the possible changes you can make fall into one of these four categories. And to make long-term progress, knowing how to change them and when can make a difference. Intensity refers to the quality and difficulty of the exercise.

There is an inverse relationship between the intensity of an exercise and its volume (sets i repetitions). Intense exercise sessions are stressful and can be extremely tiring, so you should reduce your training volume because fatigue will limit the number of quality repetitions you can perform. You'll also need more rest and recovery after intense training sessions compared to less intense sessions. Exercise increases cardiorespiratory endurance in several ways.

For example, the heart muscle becomes stronger so it can pump more blood per heartbeat. Loss of sleep, loss of appetite, persistent illness, and cessation of exercise gains are symptoms of overtraining, which can significantly affect your ability to achieve your fitness goals. Similarly, jumping from one team to another, jumping between different fitness trends, or doing exercises only for specific muscles are not effective methods of exercise. All of these benefits help reduce the risk of developing chronic diseases and, at the same time, provide various cognitive benefits, such as improving memory, making exercise as important for the brain as it is for muscles.

In addition, you will also learn the 7 fundamental rules for safe stretching, the benefits of flexibility and how to stretch properly. People who regularly participate in these activities are more likely to be physically fit in terms of cardiorespiratory endurance. As you begin your exercise program, you should keep in mind that research may provide some general ideas about how fitness can affect your body, but there are many factors in addition to the variables of the exercise program design, such as nutrition, sleep patterns, and overall stress levels, that will determine your specific answer. Fitness can also include muscular endurance, which is the ability of a muscle to continue to exert force without getting tired.

The maximum effort method, as the name suggests, is to improve the production of maximum muscle strength using extremely high amounts of weight, which, while a worthy result, is not relevant for workouts that can be easily performed with a single piece of equipment at home or in a gym. Jefit is a fitness app that comes equipped with a customizable exercise planner, a training log, and the ability to track data and share workouts with friends. They consist of an elastic belt that fits around the chest and a wristwatch that shows the heart rate of the exercise in beats per minute. Because you don't allow your muscles to fully recover, strength gains will be minimal, although you'll get more cardiovascular benefits due to short rest periods.

Let's take a look at how the FITT Principle can be applied to stretching in relation to improving flexibility and range of motion. For example, if you're looking to improve your cardiovascular condition, exercises such as walking, jogging, swimming, cycling, climbing stairs, aerobics and paddling are very effective. An insider tip that many fitness professionals know is that it's not the actual equipment you use, but the way you apply it that causes physical changes. Your fitness goal will determine the best equipment to use, the specific exercises you perform, and how often you do them.
