When I practice I have no structure what so ever! Haha I was kinda wondering the same thing. I usually just do differen moves one after another and then when I reach a move that I am really struggling with I just practise it for a while till I’m either really worn out with it or until I finally nail it then I move on. It’s hard for me to practice because my boyfriend has friends over alot and I feel weird when their there watching because they are so close minded! Haha but maybe one day I will get Into a routine workout!
