I always sketch out difficult poses before committing them to paper. The thing you’re looking for is how to inject energy into the drawing. So imagine the characters are alive and moving around on the page. Sometimes it helps to close your eyes and picture it. Having said that, you can see that I erased plenty of times before getting it right. Don’t be afraid of using the eraser! Nobody is watching and sometimes it takes a lot of bad drawings to get a good one! 🙂
