Overweight children and adolescents start off by having a fitness check-up on www.bigkidscoach.de. Based on the results, the system generates an individual training plan comprised of exercises designed to improve strength, coordination and flexibility. A 3D, animated personal trainer demonstrates the exercises on the screen. The results of the training can be evaluated graphically in a personal fitness profile and documented on a diagram. BIGkidscoach also offers a guide on sports where children can learn all about the most popular sports. The nutrition check-up analyzes typical eating habits and offers healthy eating advice.
