You mean when she makes it spin?

It's a pole-arm with a lot of weight on one extreme of the weapon. All it takes to be made spin is to be held from a point outside of it's mass centre.

Or, if you mean when she is folding/unfolding, re-watching the Red Trailer (I don't have much time now), the last shot before she unfolds sends her rolling on her back, then, as she unfolds the scythe mode, she simultaneously puts her right foot behind the left one to hold her equilibrium, and walks a couple of steps back until the scythe is completely unfolded.
