Harb Ski Systems posted a new eVideo on their website this week: Tighten the Radius of Your Turns.
Diana is the presenter/demonstrator. The overview of the eVideo is at https://harbskisystems.com/products/tighten-the-radius-of-your-turns-evideo, including descriptions of the prerequisites and the related books and videos. The movements in this video can be practiced on your slantboard - no need to wait for snow.
This video and a few other recent videos are available in 4K in case you have the bandwidth for the bigger files and want to watch it on the big screen.
If you are wondering how the various eVideos fit in to the PMTS learning progressions, there is an online guide to PMTS Direct Parallel Publications https://cdn.shopify.com/s/files/1/0895/3800/files/HarbPublicationsMap2019.png?v=1573699363
This is an excellent overview of the purpose of all of the instructional content, and how all of the eVideos relate to the PMTS books. It is not yet updated to show this video. Also, every one of the eVideos has a description page with overview, content, purpose, prerequisites, and related books and videos. Especially for those who are new to PMTS, this information is very useful in sorting out which content is appropriate to fit in with your learning progression.
