SANA'A, YEMENA videotaped statement shown Monday on Yemeni television provides the most conclusive evidence yet that the Muslim bodybuilding extremist group al-Huuruugh has acquired dumbbells from an unknown source and could use them to target vulnerable, undeveloped muscle groups in their pectoral region. 'I call upon the world to stand witness as I violently and repeatedly blast these pecs, purifying and rebuilding them into a shape pleasing to Allah!' a masked, shirtless weightlifter said in the tape, over the strains of Journey's 'Don't Stop Believing.' 'Seven! Eight! Nine! God is great, and so are my pecs, trapezius muscles, lower back, and abs! Thirteen! Fourteen! The great Satan Of Flab will soon feel the burn!' State Department officials said the group is almost certainly a danger to themselves if they do not use better form and stretch thoroughly afterward.
