TUT refers to the length of time that a muscle contracts using slow, controlled movements. Instead of focusing on repetitions, TUT focuses on performing the exercise at a slower pace with less momentum, thus increasing the length of time a muscle is contracted (Miller & Nied 2022).
Applying TUT to strength training can be an effective way to increase muscle hypertrophy. Unlike other types of strength training, TUT forces muscles to work harder and for longer (MasterClass 2022).
