Hinges ~ Core Concept ~ Horizontal X to C
Drill horizontal hinge points on fans by moving between X and C relations. Start centred at the chest in an X relation with palms facing in, then push one centre point away to create a hinge until the fans settle into a C relation on one side.
Return to centre in X, then repeat to the other side, keeping the pathway clean and symmetrical. Nikki Scarano highlights rotating your chest towards the hinging side to align the fans more easily and keep the planes consistent as you travel side-to-centre-to-side.
