glidewalking confusion

Glidewalking is difficult to get - there are a lot of moving parts to keep track of! "I can not feel my gluteal muscles because I normally walk with my feet outward." Facing the feet outwards usually increases the chances of engaging the glutes, especially gluteus medius. My guess is you are not feeling your glutes because they are not used to working when you walk. Try taking just one step at a time and see if you can engage gluteus medius (or any gluteal muscle) in the back leg. If you can't locate it, make sure your pelvis is tipped forward (anteverted) and try again. Still not working? Try pointing your back foot out a little and try again. Still flummoxed? Try raising the back leg up of the ground with your back leg turned out somewhat. This should do it. Walk one step at a time until you can contract your glutes reliably. Then try to smooth it out into a walk. Walking on a line doesn't refer to walking with your feet parallel but rather that the inside of both heels touches the same imaginary line. Good luck! Keep us posted!

Necessary but not sufficient. You need to also learn about relaxing the leg in the swing phase, landing on a bent knee, etc. But it's an important piece. Keep adding to what you have figured out and you'll get there!

Practice the inch worm exercise first (page page 211) and then integrate it into your walk. You only do a strong contraction at push off, but it helps if your feet are not too splayed to begin with (when they are very splayed / spread, the muscles at the bottom of your feet are not in a position of mechanical advantage and it is hard to engage them). For some people, this may mean your do a small amount of contraction at footfall too (or better, use a good arch support) so that you land with your foot in a good shape that puts your arch muscles in a position of mechanical advantage at pushoff.

It's normal to land your heel slightly (very slightly) before the rest of your foot unless the surface is unforgiving (e.g. cement, asphalt, etc.) This week I am on vacation in Tahoe and, having just read Born to Run, am trying out walking barefoot on some trails (I think going barefoot on natural surfaces is a good idea if you are paying attention) and am realizing that you also need to land on the midfoot when you may be landing on pebbles, poky objects, etc.

Yes. Please do share the url's of the youtube videos you have located!
