A further step: Relax your grip on the handlebar. Form a loop around the bar by touching the tip of your thumb to the tip(s) of your other fingers. At this point, you've encircled the handlebar, so it isn't going to go anywhere even though you're not really holding it. Now stand up on the pedals and try not to contact the handlebar with your hands/fingers. At this point you've really gone into a neutral position. This is useful in letting the bike roll over bumps however it wants to.
