hi mate
i also do alot of cross fit (crossfitnortheastengland.com) and found the my time's have come down and my strength has went up
don't think we worried about fighting that big cat back in the day

eating the way we should.
look at that man that your going to fight as your food that you need for your meal that night and that ya cave woman will leave ya if you don't smash his skull in and drag him home to eat
good luck for the fight
