Today’s kids are less physically active than previous generations. They’re more likely to be overweight and are at higher risk for diabetes, high blood pressure, sleep apnea, and cardiovascular disease. One Atlanta mom has made it her business to do something about that by creating Cardio Kool Kids, an innovative (and fun!) fitness and hip-hop program for kids ages 3 to 12. We got in the exercise zone with CKK founder and ACE-certified fitness instructor Amy Head for this week’s Friday Five.
