I've gotten a lot of value from Alex Kozma's Chinese Internal Fighting Arts videos and they're inexpensive. It's not Taiji but good material that was like a huge expansion of my existing Xingyi and Bagua. I've really enjoyed learning the Wang Shujin Baguazhang through this series. I've been interested in Serge Augier's Zhang Zhaodong -> Wang Shujin material and Alex is teaching that. I learned the Jiang Rong Qiao Bagua in person and this has been a fun time learning a different side of the Zhang material.
https://lineofintent.com/product-catego ... and-films/The Xingyi Academy Yanyi material is really good stuff. Anyone who has done some Xingyi 5 Elements and zhan zhuang work in person should be able to approach it. Paul Andrews takes one through basic movement patterns, how those apply to the 5 Elements, and then expands that through a selection of 12 Animals movements as well. Overall I really enjoyed a look at another line's training material for exploration of movement intent that has similar body method expression to what I learned in the Kenny Gong school.
https://www.xingyiacademy.com/onlinelearningRay Carbullido has some really clear instruction that is centered around movement patterns and expanding them into other parts of his martial arts. I studied with his senior brother locally and Ray has about 3-5 years worth of training material on his training library. The primary training method he teaches has an online course now and I learned some of his material through a seminar and registration in his online course.
https://courses.raycarbullido.com/courses/the-core-4/Kelly Whelan Enns has a number of Udemy courses available for those interested in Jiang Baguazhang and Yiquan through Lee Ying Arng. The structure of his curriculum is not exactly clear and some of the exercises are repeated in different courses.
