The World Health Organization launched this initiative as a result of the lack of physical activity in the world. Research shows that daily physical activity, motivated by self-interest and resulting in resource gains like quality sleep, vigor, and task focus, improves next-day job performance and health outcomes. 

Insufficient physical activity is a global concern, with 1.4 billion adults not engaging in adequate exercise. The World Health Organization (WHO) aims to reduce physical inactivity by 15% by 2030 through a global action plan. While the benefits of physical activity on general well-being are recognized, research on its impact on work-related outcomes is lacking. A study involving 200 employees from the UK and China revealed important findings. Autonomous motivation for physical activity, perceiving it as enjoyable, increases the likelihood of engaging in it. Daily physical activity generates resources such as quality sleep, vigor, and task focus, which contribute to improved job performance and health the next day. Job self-efficacy enhances the benefits of physical activity on sleep quality and task focus. To increase physical activity, it is advised to focus on building a daily habit, remember that some activity is better than none, and find enjoyable activities even if exercise is not preferred.
