Impressive!
I remember when I played Rugby they rewarded us with around 12 kegs for winning all 3 grades one season, one of my mates only ever played centres or on the wing, he ranged around 7-9% body fat and ran the 100 in 11 seconds flat.
In the week after the grand finals..........he put on 12kg.......lol it all went to his stomach and face, I swear he looked like ET the following weekend, it then took around 4-5 weeks of hard work for him to drop it.
