Hey
i do a lot of breaking myself and picked up girls i've trained with so i got a few tips.
Kino:
Kino is very easy when it comes to breaking. Helping the HB with stretches is always a good one, its not intrusive and can lead to EC if your helping them with backstretches.
Negs:
'Nice move, i've seen a seven year old on youtube do the same as that'
'Your training is coming along well, you should crack a 6 step soon'
Other random bits and bobs:
if theres a move that she is struggling with and you have got it, wait till the next time she tries it and then do it. 99% she will ask for your help, reply in a cheeky manner 'only if you can give me shoulders a quick massage, all this training is killing them'
Cat-String Theory is also very easy in breaking, just get talking or helping (best towards the end of a song) then when the new one comes on just walk away and start breaking, pull off your good moves though because she will still be watching.
Hope that helps dude.
let me know how it goes
