Book Title: Official Taekwondo Training Manual Authors: Soon Man Lee & Gaetane Ricke Taekwondo Style: WTF Taekwondo ISBN: 978-1402727078 Amazon: Summary Recommendation: This is the only English-language taekwondo reference to receive a Kukkiwon endorsement, so if you're a practitioner of WTF-style taekwondo, this is definitely a reference book worth considering. The only real competitor to this book is Lee & Kim's Complete Taekwondo Poomsae. Disadvantage: some readers may be put off by the fact that the photographs in this book are only black & white. If you really must have color photographs, consider Park, Park & Gerrard's book TaeKwonDo.
