Bathurst, New South Wales, Australia / November 6, 2025

Matthew Lawson loaded seven 20 kg plates, 140 kilograms in all, onto one arm of a plate-loaded Viking press at a gym in Bathurst, Australia, and pressed it overhead with his left arm for eight straight reps. A Viking press is a standing shoulder-press machine worked through lever arms with handles at head height; on this one each arm moves on its own, and the continuous video shows the other arm parked while the left handle travels from shoulder height to full lockout eight times in a row, with the seven-plate stack in view the whole way. Seven plates, one arm, eight reps.
