"Cardio Kool Kids" creator Amy Head says the instructors go into schools, churches and rec centers, wherever the kids are.
The group meets weekly over several months.
"We bring the program to the children. It encompasses really the whole child. We talk about nutrition, and lots of topics around health and wellness," Head says. "What I should and shouldn't eat."
School officials say this after-school program simply adds to what the students are learning in school.
"It is fun but it's also becoming part of a healthy lifestyle that we try to promote here. They know it's a good thing to be doing, and it just falls in line with the other things that we promote throughout the school day." Head says.
Learning, pllus fun with friends, an equation worthy of an 'A.'
