She actually looked OK while working with Edmund, but cut to a close up of her shadowboxing with the purple weights in her hands and she looks like she's not all there mentally, and again on the wide angle of her in the middle of the floor.
At that point Mike must have been thinking "Wow her technique is actually dogshit".
Also those GIFS might be at different speeds but I've seen that footage of Mike many times and damn he was fast, tight and compact...dynamite in those hands.
