This book is all about quick access to information. IҶe taken feedback from other books onboard where people said it was too expensive, there was too much information and they just wanted to dive straight in. This book is cheaper than other books as IҶe left links to additional videos out and cut things down to just the essentials. I am including a bonus voucher code toward the end of the book which you can use to purchase a 2 hour streaming video which covers all the information covered in these 21 days step-by-step, itҳ fully optional to purchase and not required but a great additional for those who are more visual and like to hear someone talk. You can also find the DVD on Amazon by searching for 21-Days to Kettlebell Training for Beginners DVD Bonus You'll also get a voucher for the Udemy course and Android app which means you can either get yourself a certificate through Udemy and/or play the videos via the mobile app on your TV. Combined with this book these resources will undoubtedly help you lay the best foundation for kettlebell training.
