This is my first go at these after straining my left oblique. I am trying to take it easy on this and not spin my wheels, so I started with 3x2. It was admittedly easy regarding exertion, but the ROM when twisting my left oblique was noticeably stiff. I'm probably not ready for mastery yet, but I still marked it easy for today. Once I find that the ease of the movement and my exertion are somewhat equal, I intend to work on my left obliques comfort and ROM. Let me know what other form points stick out.
