I posted a video not too long ago about Two Ways to Run Faster — Even When You’re Tired.
In it, I discussed how you can incorporate more “trunk and core” muscles, essentially asking larger and stronger muscles to propel you down the road.
The video lead to some great questions about wasting energy and overall running efficiency.
I’ve heard this a lot in the past decade as a Physical Therapist. And while there’s not a lot of great research looking at running efficiency and upper body motion (it’s pretty diffucult to measure), we can fall back on to what we know about human movement and anatomy.
It’s what I cover in this quick video about why running from the trunk is a good idea.
