What I found easiest way as I've just learnt them, was to just stand on bike and pull front up for as long as I could just to help me find my upright balance, once I could hold it for a while I then started to hop. Gave up the other way as I was hopping all over the place into things and landing on my ass a lot. Thats what worked for me just getting the balance before the hop, doesn't hurt as much when you come off as well, lol. Also found pulling front up slowly helped better than trying to pull up hard and going to far backwards...
