Too many strength programs focus soley on building concentric strength, with full range of motion exercises.
These movements are loaded and usually too slow to be very functional for running. And target building muscle fiber MASS/DENSITY rather than utilizing MORE muscle fibers. More fiber mass just requires more oxygen and energy - not efficient. Creating more muscle fibers allows you to use more mitochondria, which is the muscles energy powerhouse!
And most times these slow, heavy, massive range of motion exercises do not target tendon strength, elastic rebound, and the stretch shorting cycling in the running gait.
In running, the range of motion is not very great and therefore tendon strength and stability come into play, and why the strength program in The Cool Impossible focuses so much on foot, leg, glute isometric and stabilization strength. It's not sexy, but very potent and works very quickly.
•
Bottom line, if your concentric strength over powers your eccentric strength and isometric transition, your running will suffer in many ways.

Today's Second Run Session after morning track:
WU: 10' easy.
MS:
5 X 60" fast downhills with a focus on good foot strike, quick knee drive and relaxed propeltion downhill.
After each, a very easy 90" run back up with a focus on forefoot strike and very quick cadence.
•
》Downhills = train my eccentric and isometric abilities, the landing. This is tremendous strength training BUT foot strike must be a focus.
》Uphills = this trains my elastic properties in my arch creating a better "spring or rubber band" to help propel me forward.

Hi Eric, thank's for this, very usefull, as usual ;-)
I followed the programm in your book last season. Amazing transformation! No injuries!
The sugar detox was very usefull and I kkep going in my sugarless diet !
Thank's for everything
Maybe see you In France???
