The record for the most sumo squats in one hour is 5,135, and was achieved by Dr. Thienna Ho (Vietnam) at the San Francisco State University, in San Francisco, California, USA, on 16 December 2007.

She was trying to attempt the most squats but the position was different to the squats made by the record holder at the time, Paddy Doyle, so the category of sumo squats was created. Thienna Ho used the record attempt to promote her book about healthier and whiter skin. Carlos Martinez adjudicated.
