“Force” Method Critique

I've been figure drawing for about 4-5 months now and I'm beginning to be able to capture movement but my figures however still look and feel very stiff. I recently got Michael Matessi's book on the force method and it's helping but I find it quite difficult to put in to practice. These are my attempts using the method with on some 5 minute poses.

I was wondering what specific things I should work towards to make them more fluid.


Thank you !!
