I think I discovered what the problem was. Instead of dropping myself to the front/tips when initiating the turn, I somehow dropped myself into the center of the turn (at least my mass, my torso was quite vertical). I hope you guys understand what I mean by this, because I find it quite hard to explain a feeling in a non-native language
, you're simple exercise worked pretty well (hold hands on knees throughout the turn), although it's quite a hard exercise. It sounds simple, but you loose your hands/arms to balance through a turn.
Others, I will be trying each ones advice, although it may take some time, because it's quite high-level talk over here, but I'm prepared to learn
