Yak Attack training #4

Im doing some lunch training these days.  Mild dedication, but also just a really good excuse to not sit at desk through lunch and to actually take a break.

15 degree incline on treadmill is all it'll do. Backpack with 25lbs which is bike and such simulator. Hour up. Idea is to help legs get ready, but also torso. Is rather have nights of recovery there applied to other areas of body than a back in shock and sore from load bearing. 

Why does 25lbs feel so heavy in a backpack context?!
