Is your RI asking you to keep your torso upright during rising trot,Yvonne? If so, this is the cause. If not, try putting a balance strap between the Ds of your saddle and hook your little fingers through it. Allow your forearms to rest lightly against your hipbones. Keeping the hands low and stabilising the forearm really helps.
My RI is not telling me to keep the torso upright, so that is probably not the problem. I do have a balance strap and I did try putting my finger through it on my solo ride yesterday after my RI noticed that I had way too much motion. I still felt a slight motion even when having the strap helping me out.
(i) Should the hands be *absolutely still* or does it take a lot of time/practice to achieve perfect motionless hands - is a small amount of motion (just a slight wavering/motion) acceptable in these early stages of riding or should I be capable of total still-ness at this stage of my riding - what can I realistically expect of myself here? Thanks.
(ii) So if the hands don't move in response to the human body's motion during the rising trot, do the elbows then need to be soft and do some gentle flexing etc. to take up the motion of the body???
