Perfect Technique for Climbers is an e book published by Paul Barr via Kindle. It is available from here.
If you have purchased the book, the videos should be able to be accessed from clicking on the link from the Kindle app. Should this fail to work, the videos are all available below. Should you wish to make copies of these videos to view off line, this should be possible using a tool to download them from youtube. If you are unable to undertake this, you can email me at email@example.com
I hope you have enjoyed the book and are making progress in your climbing technique improvement.
