I third what rm -rf said. Fore-aft saddle position is one of the most critical bike fit adjustments and most people never even bother to adjust it. Your saddle being tilted up in the front indicates that you are probably trying to stop yourself from sliding forward. This usually means that the saddle is too far forward relative to the pedals. As a first step, try sliding the saddle backwards and flattening out the tilt. That should also take weight off your hands, which should have almost no weight on them. If that results in the handlebars being too far forward then you need to buy a shorter stem. Never try to compensate for too much reach to the handlebars by moving the saddle forward.
