In December 2019, the new coronavirus pneumonia (COVID-19) exploded in Wuhan (Hubei, China) and spread rapidly from one city to the whole world. This virus resulted in a total of 1679720 confirmed cases and 101734 deaths worldwide. All countries in the world are taking some precautions to prevent the spread of this epidemic disease, which World Health Organization (WHO) declared as "epidemic". Staying home and social isolation are among these precautions. For this purpose, it began to implement the curfew for all individuals on 10 March 2020, Turkey. However, not leaving the house and social isolation bring about the limitation of physical activity. Physical activity (PA) is defined as anybody's movement produced by WHO by contraction of skeletal muscles. Studies investigating the relationship between social isolation and health behavior report consistent findings. Individuals with smaller social networks report less healthy diets, excessive alcohol consumption, and less physical activity. Traditional exercises; It takes place outdoors in gyms or rehabilitation centers. However, with the increase in the time we spent at home due to the coronavirus (COVID-19) epidemic, technologies have been used as an alternative method. Home-based exercise programs are also a viable solution to prevent various health problems that may be encountered in this direction. The decrease in physical performance is associated with loss of muscle strength, low quality of life, emotionalization, comorbidity, premature death, and increased health costs. When today's conditions are evaluated, technology-supported education programs are effective in increasing motivation for physical support. The purpose of this study; To prevent the spread of the COVID-19 outbreak, to evaluate the physical activity levels of individuals between the ages of 18-40 who have social isolation due to the measures taken in our country and to investigate the effectiveness of their video-based exercises.

Sedentary life invites various diseases. Especially cardiovascular diseases are the leading ones. Researches show that the rapid development of technology has pushed people to laziness and therefore to immobility. A sedentary lifestyle causes many serious health problems. Many diseases such as obesity and cardiovascular diseases, which are characterized as contemporary diseases, such as muscular weakness, postural disorder, and diabetes are more common in immobile and sedentary individuals.

We know that still life has some drawbacks. These may cause tissue injuries between the vertebrae and kyphosis, lordosis, scoliosis problems, respectively. It may also cause calcification in the lumbar vertebrae, disc problems, risk of sciatica, and an increase in excess adipose tissue under the skin. Again high blood cholesterol and triglyceride findings and blood sugar abnormalities may occur in the blood table. Of course, the susceptibility to high blood pressure, the loss of elasticity of the rib cage, low respiratory capacity, and the risk of coronary vascular disease may be uncertain. Still life can create weak abdomen and back muscles, posture disorder, digestive and excretion difficulties, postpartum drooping abdomen, hip slope abnormality, loss of strength, flexibility and functionality in all muscle and muscle groups, weight problem and formlessness. Also in skeleton structure; osteoporosis, calcification, joint problems, easy injury, weak body, easy sickness and recovery can be observed. All these diseases are serious health problems that can be encountered in individuals who do not exercise regularly. In many developed countries of the world, people have included sports in many compulsory habits such as eating, drinking, lying, education, and worship. This compulsory exercise is a lifelong activity in humans. People who make it compulsory to exercise will feel discomfort as soon as they do not.

At the moment, we know that the most valid method to protect against coronavirus is to stay at home. Many scientists are told that this virus protection is to strengthen the immune system through exercise, and that the weight problem can be eliminated with exercise due to staying at home all day long. Because, it is explained one by one that exercise will increase the body resistance of the people, children and adults will stay away due to movement from obesity, the skeletal-muscular system will be regular, and the social environment will make people healthier.

In addition, constant home, restricted mobility and freedom, limited sociability, decreased communication, increased social-physical distance with our loved ones, and decreased physical contact can make us more depressed, angry and anxious.

For all these reasons, the home quarantine process created due to the Corona virus necessitates exercise. We believe that this process can be managed in the most effective way with video exercise and information booklets in order to reduce inactivity in this process, which is left at home with the philosophy of life is movement, movement is life.

Science and technology have been developing since the day human beings existed. Technology; It is used in many fields such as education, health, communication, defense, industry and transportation. Technology has brought many benefits and a new perspective to the health sector as well as other fields. In this study, it was aimed to investigate the effects of the exercise program that we applied remotely with video-based exercises during the quarantine days on the parameters such as physical activity level, balance, endurance, sleep quality, depression, anxiety and quality of life.
