Along with those that Keith has explained, I've been trying this cue.  This picture appeared on SPIKES' twitter feed today (https://twitter.com/BritAthletics/status/697675957847638016).  The picture shows twins who train together, but one clearly has her pelvis tipped further forwards.  They appear to be at the same point in the stride cycle (albeit opposite legs).



Coincidentally, I've been dabbling with the pelvis tilted further forward than my legacy running style, and it feels very balanced.  It can be achieved at all paces, and I'm convinced it helps me land under the hips more successfully.

I am also aware that over tilting the pelvis forwards can cause injury, but I don't think there's any danger of that for me.  I'll film again soon just to be sure.
