This is a very interesting presentation (I wish that it was in text instead of being a video).

About half way through my thought was "OK, for elite athletes training 20+ hours per week, a whole lot more easy training and a whole lot less (on a percentage basis) hard training is proper. Does this have anything to do with mere mortal folks who train much less - kind of doubt it".

Then at around 27:00 some data (kind of hard to figure out) is presented that says that even at much lower levels of training this same 'way more easy stuff' seems to work. It is hard to tell exactly what those levels are in that part of the presentation as total time was stated but not over what time period, but way less than 20 hours per week I feel sure.

I really wish that I had a text version of this thing - I think that it is pretty good stuff. Thanks for posting.
