Kids challenge book

Recently, my physique has improved, but there are more children who can't climb backwards, can't run fast, can't fly jump boxes, and can't swim well. 
 In this book, parents and children can move around while playing to learn the fun of horizontal bars and to be able to run fast. It was released as a guide for people who want to try. 
 All color and cute illustrations are included for easy explanation. 
 Why don't you read with your child and have fun outside?
