Is sumo cheating? We did a study to find out 
Is it cheating to use a wide sumo stance for the deadlift? Officially, the sumo stance is accepted, but unofficially, many people claim that sumo is cheating. The idea is that it's easier to lift a given weight with a sumo stance than with a conventional stance.
Many arguments have been put forth about this question, usually citing powerlifting records or biomechanics. However, to my knowledge, our study is the first to test sumo and conventional deadlift 1RM strength within the same subjects.
