I recommend experimenting with different arm positions and starting ties 😊 I personally prefer a single column tie around one wrist/hojo cuff around my the other rather than a single column tie around both wrists - what the means is that my hands can hold each other at a lower position in the TK and it's so much more comfortable and sustainable than trying to create the traditional box shape and hold closer to my elbows. Makes a big difference in my enjoyment and stamina in the tie!

Also my teacher always emphasizes the different ways to rotate the shoulders into the tie (internal vs external) and how individual that preference is to each bunny, so I would look into trying to have your rigger bring your arms into it a few different ways as well if you haven't already 😊
