Here is my attempt

Please try to avoid contours as much as possible at least in the context of the gesture drawing exercise for now just focus on the core of the body rather than contour Here are some of my examples And by no means mine are perfect If you find anything weird let me know

Hey Tobias, One reason you are struggling with this is because you are focusing too much on anatomy. Gesture isn't about making it look like the model, it's about capturing the "story" of the pose. Where is the weight, where is the stretch, where is the pinch. You must find an "S" or "C" curve that describes the pose from top to bottom. One continuous line. Disregard anything that doesn't contribute to the gesture. Also, this is much easier to do if you draw with your whole arm and not just your wrist. I included a drawing of how I would think about this pose as a gesture drawing, I hope it helps :)
