BMX bunnyhop PROGRESSION for NOOBS

I learned how to bop the bike both wheels up simultaneously at 15 but never learned the proper bunnyhop where the front wheel lifts first. I found a bmx during council cleanup and recently decided to give it another try at twice the age. Watching this video really helped as it broke down the bunny hop into steps. The part where she shows rear wheel hops, really helped as that scooping motion, I did not get. Also the suggestion that a little jump could help gave me the idea of bopping off a little axe handle to help with timing. I noticed that my biggest issue is that I brute force it up but all my efforts fight against each other. My next goal is to use my back muscles and pull back on the bike rather than use my arms to pull back while I am crouched over the bike like hunchback.  Here is other videos that helped.  When he says "its all about technique, you should be able to bunnyhop as high as you can pull the front wheel up". That was quite inspiring. I trained pretty intensely about 10 minutes each day. I could not do much more than that because I have damaged wrists from other activities. I gave myself about three days rest inbetween. These are the results after 4 days of training, 10 minutes each.
