To improve the fitness of primary school students, the WELL AP should recommend implementing a policy to offer sports activities for students at no cost for 75 minutes every school day. This recommendation aligns with WELL features that promote regular physical activity, which is vital for the growth and development of children. By ensuring that sports activities are offered every day without cost, the school would encourage consistent participation, helping to establish healthy habits early in life. This strategy is most effective because it integrates physical activity into students' daily routines, supporting both physical and mental well-being.
