A 1RM strength sport where athletes perform four movements—this includes the bar or ring muscle up, pull up or chin up, dip and barbell back squat—while adding as much weight as they can handle for one repetition. The goal is to lift the heaviest weight possible in a single attempt, showcasing maximum strength and technique. Athletes are allowed three attempts at each exercise. The biggest achieved lift for each of the four exercises are then added together to give the athlete their total, and the athlete with the highest total is deemed the winner.
