Super Slow is a form of resistance training popularized by Ken Hutchins. The term SuperSlow and derivative terms are registered by Hutchins as trademarks. (To avoid confusion, and avoid legal battles with former business associates, Hutchins has renamed his methods "RenEx" and "Renaissance Exercise".) Super Slow involves the combination of very slow speeds of lifting and lowering the weight, along with the general principles of the High intensity training approach advocated by Arthur Jones.
The 10 second lifting, 10 second lowering repetition speed (slow resistance training), originally invented and patented by Dr. Vincent "Ben" Bocchicchio, was suggested to Ken Hutchins by Dr. Bocchicchio. Hutchins further developed the protocol during Nautilus-funded osteoporosis research at the University of Florida in the early 80s. An identical method to the current Super Slow protocol was used in the 1940s by body builders as a plateau breaker under the name MC/MM or muscle contraction with measured movement. The repetition tempo used in MC/MM was 10/10. Therefore, Hutchins did not actually invent this type of training.
The method incorporates very slow repetition speeds as compared to traditional resistance training methods, with emphasis on minimizing acceleration to reduce the force the body is exposed to during exercise and improve muscular loading. Super Slow workouts typically consist of one set of each exercise carried out to complete muscle fatigue. Ken Hutchins recommends performing each set for between 100 and 180 seconds. A frequency of twice weekly is recommended for most trainees, with even less frequency for more advanced trainees. Some research indicates that Super Slow produces superior results compared to traditional methods in as little as 10 weeks
Slow repetitions may be beneficial to trainees working around injuries or conditions requiring extra caution, and may be useful for practicing proper form when learning new exercises. Many personal trainers who have abandoned Super Slow for general use, still use it as a method for teaching new exercises or evaluating clients' exercise form.
Similar methods include Fred Hahn's Slow Burn system and Adam Zickerman's Power of 10 method. Zickerman's Power of Ten is identical to Super Slow in rep speed and philosophy. Hahn's Slow Burn method does not subscribe to the strict 10/10 rep tempo, and uses of a heavier weight load than Super Slow. In Slow Burn training, the weight load chosen renders muscle fatigue in 40–90 seconds. Hahn also recommends two sessions per week for the vast majority of trainees. The word burn in Slow Burn is used to describe efficient fat burning via the use of a low carbohydrate eating regimen not the feeling of burning muscles while doing the exercises.
