Ready, Set, Go! 5210 is partnering with worksites to share the 5-2-1-0 message and workplace wellness practices. The primary target of Ready, Set, Go! is children and youth from birth to 18 years old. However, Ready, Set, Go! in the workplace aims to expose parents to the same 5-2-1-0 message that is being delivered to kids and families at schools, after school, the doctor’s office and in communities.
