My very first instructor ( I went through many ) did me a huge favor by saying, "let go of the yoke" about once every two or three minutes, until I learned to trim. He could tell when I was hanging on for dear life - and he'd bust me on it. There's several good hints in the posts above - Just remember, most trainers are positively stable - all they need is a hint of where to go, and they'll do most of the work. Kind of like my neighbor's cows - they know the way to the barn, but without a little bit of guidance, they'll be out, well, " 'till the cows come home."

As Pharo says, once you've got the touch, it doesn't go away, and your captains down the road will appreciate it when you got your jet trimmed so that you can just turn loose for a few moments to adjust the climb power, take a sip of your coke, or to slather some fresh gel onto your hair. (sorry, just kidding on the last one!) Seriously, it'll make a world of difference in your flying.
