If Rugby is your thing, then to truly stand out from the crowd you just need to change your diet.
My team spent most of its time chasing girls, drinking beer and eating chicken wings, in addition to training hard. Train hard, but eat consistent high protein meals, and ditch cardio for sprint exercise.
Once you start putting on the lbs and gaining speed, no one can stop you.
Play like a running back, and run through all the hung over skinny-fat fuckups that get in your way.
Victory or Death.
