Riders may apply unnecessary weight onto their hands along with shoulders and neck issues as well as numbness of fingers further with the saddle height which might have been set too high. You might also observe that your torso actually seeks to squeeze down between your shoulder blades and this throat position is easy to capture on your action camera mounted on the trainer. Additionally, more than half the time, this position is not due to aerodynamics but comfort, suggesting that the handlebars are set too high.
