About

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

Matthew Lawson loaded eight 20 kg plates, 160 kilograms in all, onto one arm of a plate-loaded Viking press at a gym in Bathurst, Australia, and pressed it overhead with the left arm alone. A Viking press is a standing shoulder-press machine worked through lever arms with handles at head height; on this one each arm moves independently, and the continuous video shows the other arm parked while the left handle goes to full lockout seven times in a row. The plate count is clear on camera, and a training partner keeps a hand on the end of the sleeve only to hold the plates on. One arm, eight plates, seven reps.
