+Deyshawn Clarke-Wells Yes, we have found it to help the free leg positioning and it goes well with the holding of position off the board work we’ve been doing too. Thanks.
Here's a link to some thoughts and another video on weight training to improve your jumps and sprints performance. Many athletes are unsure about exactly what to do in the weights room and how how you lift can actually help benefit your performance (and not just make you good at weight lifting!). www.johnshepherdfitness.com/blog/october-30th-2017
Nikes, Many thanks for your comment. Jeremy is a top coach and certainly knows his stuff! This video of mine may also help you; it focusses on how to prepare to jump (penultimate step) and also shows albeit briefly some wicket/low hurdle runs, which are great for developing speed. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PSA8lJDDRmU.html In time I will also pull together a specific video on long and triple jump run-up speed development.
