I was actually lucky when learning the back kick and got a super helpful tip.And yes i did read that backward finning is extremely hard.
So first I tried it by myself on day 1 on a 100% recreational LOB, and there was a guy who saw me and said: "once you have your legs extended and the fins tips pointing out, just spread your legs, thats all"
On day 2 that tip made all the difference and everything clicked and the back kick happened. After that it was just finessing it
maybe it will help you as well
