Train Hard - Stay Humble
Every so often, at GWHS we practice rolls on the the big sport field, either jumping from a stand on the perimeter rails, or running into it from the field itself.
It's safe and a good basic training...
It is important, though, to think at the roll as something that should become automatic in certain conditions and on (almost) any ground.
Even if you don't drop (as you shouldn't...) from heights, or you don't necessarily feel you need it yet, truth is, you never know when you need a roll, because of an off balance landing, a sudden misstep, a forward bail or else.
That's why we practice: to be ready for emergencies... the need to avoid landing on your face, twisting a wrists falling, or spraining a knee look like an emergency to me!
And remember: SLOW PROGRESSION!
We didn't invented it, it's always been there... because it works!
