Down in the Core

For a while now I have been avoiding having to work on my core, but the other day I observed something that may get me doing crunches. While I was running I noticed how much work my body was doing just keeping my upper torso errect. By the end of my run (1hr 30min) my core was pretty pooped. I've also observed core fatigue during my swim program spcifically when I'm working on my kick. Not sure how/when to work in some core development but my guess is that it will help my performance.


I think my Tensor Fascia Latae might be to blame. It burns like the dickens when I bike.
