what doesn't kill you eddie, will only make you stronger.
-Random chasing around field - Improves your running speed, and maneuverability!
-Throwing fully inflated coke can at head - improve your reaction times
-Pushing over on icy concrete - gets you to practice stability
-Throwing pegs at face - improve your reaction times with small objects coming at your face, like paintballs
and my personal favourite; Zip tieing the circulation to my hand off (after random chase round field and pushing over) - helping you to learn to work under pressure
I'm off to Surrey for the week, I may not have access to the net. Talk about cruel and unusual punishment!
