Is anyone having an advice to get better at the box ? I struggle at 5 cycles

Hi everyone, today I learnt "abracadabra", for this trick you need to juggle 2 balls in 1 hand with a 3rd ball in the hand. But cannot do it because the 3rd come from a throw and I can't place it correctly in my hand, it stay on the fingers and don't go on the palm of my hand. If someone has some advice...

Hello, I'm working on the 5balls cascade and I don't progress on the 55500 alternating with 3balls cascade. Does anyone have any advice on how to remedy this stagnation?

My best trick : 5balls 5catches succeed 1 attempt /10 My dream tricks : 5balls 20 catches, 6 balls 12 catches
