When I walked into the Roxbury classroom, I was a newly minted ex-smoker looking for something new to help re-pattern my life.  I couldn't take a punch -- couldn't much throw one, either.  I didn't know my limits or how I would respond when I hit them, and I was apprehensive about my ability to stick with something both physically and mentally exhausting.  Ten months later, that feels like lifetimes ago.  Ten short months, and though I know I've barely even started down the path, I feel sharper, more confident, more able, and safer than I ever have... and I've quietly carried myself over a lifetime hump of being unable to stick with challenges.  Krav is no longer something new I'm trying.  It is something I do, and something I will continue to do long into my life.
