Set of two books. Both are blank. They also cover sports, nutrition, and taping. It may be difficult to see, but I've included the table of contents for each text, so please take a look. [About the Content] This is a text where you can learn the basic theories and concepts common to various sports, not just specific ones. While it's geared towards instructors, I think it's structured to be useful for those with sports experience or those who will be involved in sports instruction/support as a review. I'm offering this for sale in the hopes that those who need it can make use of it. [Condition] ・No writing ・Slight scratches from storage ・No major stains or tears If you have any questions, feel free to comment. Thank you very much. Thank you for looking!
