Viking "Berserkers" were an elite group of Viking warriors. Known as "Odin's special warrirors", they fought with such insane ferocity that they didn't even distinguish between friend or foe! Basically, anything that came near a Berserker while in a trance-like fury was about to become hamburger meat!
Celtic Hammer Club has used the legendary intensity of the Berserker warriors to create this line of gym apparel for those of you who like to go berserk in the gym! There are tanks, muscle shirts, and t-shirts featuring a very intense, over-the-top Berserker getting his swole on.
"His (Odin's) men rushed forwards without armour, were as mad as dogs or wolves, bit their shields, and were strong as bears or wild oxen, and killed people at a blow, but neither fire nor iron told upon them."
