+1. When you ride, try to consciously maintain a relaxed grip on the handlebars. Especially when standing (like going up a hill). There is upper-body involved there, basically you're not just standing on the pedals, you are also pulling your body down onto the pedals (to verify, crack a rib and try to ride up a hill standing). Even in that situation, try to avoid a clenching death-grip. You only pull with one arm at a time, try to relax the non-working arm.
