Tips and rotation exercises to help with rotating my axel?

Yesterday, my coach said two magic words: AXEL PREP. I, of course, now can’t stop obsessively jumping off ice axels everywhere I go. I’ve only been attempting them for one day, (lol) but I’m consistently half a rotation to a quarter rotation short of the full 1.5.I have solid single jumps and good height on my axel attempts. I can also jump 1.5 basic rotations from a standstill, but when I put it together with the entry and snap in I can’t complete it yet.Does anyone have tips, exercises, drills etc to help with rotating faster and getting that last bit of revolution? I know I’m at the beginning of what’s sure to be a long axel journey, but I’m excited and want to work on what I can ASAP!
