Children in the Netherlands are champions of not moving. While exercise is important! Matrix Fitness emphasises the importance of exercises for children. Together with Matrix I’m the proud initiator of the 10@10 Challenge, based on “10 minutes of exercise every day”. This year was the third year of the 10@10 challenge. Since the start of the initiative a couple of 100.000 children participated. Every year I visited one of the participating schools for a great workout with the kids.
