You should be looking down at the bottom and a little in front of you. So in a pool you should be looking at the bottom of the pool about 5 feet in front of you.

So I should have my head totally under water? I will give it a shot next workout.

I would call that every other stroke deepbluex.

You pretty much want to have your neck and spine in perfect alignment. If you are looking up to much, you hips will lower and add more drag to swim stroke. If you are looking down to far, it makes it more difficult to breath and also adds more drag due to the position of your head.

For the most part, I can navigate by only looking up for the buoys a couple of times per buoy and use the rest of the time by watching the direction everyone else is swimming near me to simply follow the herd. This allows me to keep my head down most of the time.

I tried to get the "down hill" feeling yesterday and it felt like I was almost "forcing" my body and head down. Am I pushing too much?

I also felt like I was rocking back and forth the whole time trying to turn my body to breath rather than just my head. Is that the right feeling or am I rotating my body too much?

I disagree with this. While this is what is taught in the TI method, this idea of rotating the whole body takes much of the power out of your stroke. Imagine a baseball player, golfer, or quarterback who rotated their entire body instead of just their torso. Try it with a golf club or baseball bat in your hand. Instead of just twisting your torso, rotate your entire body, including your hips, as far as you rotate your torso. How much power do you have?

The power in any sport - whether throwing a punch in karate, or making a hole in one, or batting it out of the park - comes from the twisting of the torso relative to the core of the body. Unleashing the power of this giant "spring" is where your force comes from. Swimmers who rotate their entire body in a "belly to the wall" manner lose most of their power. Watch any video of a really good swimmer, like these of Ian Thorpe:

and you can see the twisting of the torso, but not the turning of the whole body.

And this is an ongoing debate! Personally, I find there is a difference in body rotation from sprinter (Ian Thorpe) and long distance swimmers. There is less rotation when you are kicking harder (sprinting) with triathlon swimming you rarely kick, and I find as a result I rotate more. As well there is a longer glide period with longer distance swimming witch allows the rotation in a 'fluid' movement.

the drill is to get the feeling, not what you will do while swimming. You never fully rotate. If you don't rotate at all you will suffer shoulder injuries as a result of forcing your body into a unnatural position. The power loss is there. Strong swimmers like Ian Thorpe are stronger, and thus able to gain more benefit from a power position, however, most of the rest of us will gain more benefit from an efficient position i.e. more rotation.

Just what I have learned from my experience, and it works for me.

What about those new speedo goggles designed by Phelps' coach that are supposed to promote proper head position? Are they any good?

I agree with deepbluex in that you don't have to continuously look forward in a race to stay on track. I have learned to periodically look up, facing forward with my goggles slightly above the water surface and spot the next big red triangular or round thing sitting on the water. Like someone else in this thread said, I do not take this opportunity to breathe because my mouth never breaches the surface. I will wait and breathe again on my next normal stroke. For the rest of the time, my head is down and hopefully I'm drafting off someone. Be careful when "following the pack". Maybe they're not taking the most efficient path either.

I've also been experimenting with head position, since I saw some "real" swimmers appear to have more of their head out of the water than I did. I definitely agree with geochuck on this, depending on your body type, %fat, muscle distribution, etc., a positon that is good for one swimmer might be counterproductive for another. In my case just raising my head a little (I was looking down too far) was really instructive - I felt a reduction in drag immediately. It was a wonderfully amazing thing, and I'm sure I could still improve with some video analysis.
