High-intensity training (HIT) is a form of strength training popularized in the 1970s by Arthur Jones, the founder of Nautilus. The training focuses on performing quality weight training repetitions to the point of momentary muscular failure. The training takes into account the number of repetitions, the amount of weight, and the amount of time the muscle is exposed to tension in order to maximize the amount of muscle fiber recruitment.

Unlike traditional workout routines that emphasize long hours in the gym, HIT principles require short but highly intense workouts. Exercises are performed with a high level of effort, or intensity, where it is thought that it will stimulate the body to produce an increase in muscular strength and size. Advocates of HIT believe that this method is superior for strength and size building to most other methods which, for example, may stress lower weights with larger volume (sets x reps x weight).
As strength improves with high-intensity training (HIT), the weight or resistance used in the exercises should be gradually increased over time. This progressive overload is believed to provide the muscles with enough stimulus to continue improving and growing. An inverse relationship exists between how intensely and how long one can exercise. As a result, high-intensity workouts are generally kept brief. After a high-intensity workout, as with any workout, the body requires time to recover and produce the responses stimulated during the workout, so there is more emphasis on rest and recovery in the HIT philosophy than in most other weight training methods. In any workout, not just HIT, training schedules should allow adequate time between workouts for recovery (and adaptation).
While many typical HIT programs comprise a single-set per exercise, tri-weekly, full-body workout, many variations exist in specific recommendations of set and exercise number, workout routines, volume and frequency of training. The common thread is an emphasis on a high level of effort, relatively brief and infrequent (i.e. not daily) training, and the cadence of a lift, which will be very slow compared to a non-HIT weight training routine.
Most HIT advocates stress the use of controlled lifting speeds and strict form, with special attention paid to avoiding any bouncing, jerking, or yanking of the weight or machine movement arm during exercise. Technical HIT advice varies from lifting the weights smoothly and at a natural pace, to timing the lifts, peaking at hold and descent. In extreme cases, like Ellington Darden PhD's 30/30/30 protocol, it may take up to 60 seconds to complete a single repetition.
Also emphasized when near exhaustion in order to further exhaust the muscle or muscles exercised: doing static holds for periods of time, and negative reps (lowering the weight). Some believe this will stimulate further growth and strength because muscles are weakest in positive/contracting movements (sometimes referred to as first-stage failure of a muscle). Although you may not be able to lift a weight for another rep you will almost certainly be able to hold it statically for a further period (second stage of failure) and finally lower a weight at a slow controlled speed (third stage of failure). Until all three (lifting, holding and lowering) parts of an exercise can no longer be completed in a controlled manner, a muscle cannot be considered thoroughly exhausted/exercised [ citation needed ].
A large number of skeptics dispute the methods and results claimed by HIT advocates. [2] Some of the criticism asserts that HIT violates much conventional "wisdom" in weight training. By always using a weight that one can lift 8-12 times, using 4 second negatives, and so on, it has flown in the face of the exercise establishment. [3]
There exists also an issue related to the development of HIT and its originality. Near the close of the 19th century, a medical doctor by the name of Gustav Zander developed a complete set of machines and a workout method remarkably close to that promoted by inventor and HIT enthusiast Arthur Jones in the early 1970s. Jones acknowledged Zander stating:
So, in attempts to improve my exercise results, I designed and built a total of about twenty very sophisticated exercise machines, then believing that these were the first exercise machines ever built by anybody. But many years later, I learned that a doctor named Gustav Zander had designed and built a number of exercise machines in Europe nearly a hundred years before I built my first one; I did not copy Zander's work and learned nothing from him, was not even aware of his work until long after I had made the same discoveries that he had made. But if I had known about, and understood, Zander's work, it would have saved me a lot of time and a rather large fortune in money, because the man was a genius; his only problem was that he lived about a century ahead of his time, at a time when very few people cared about exercise and even fewer knew anything about it. [4]
Regardless of who originally developed the systems (and machines) it is clear that through Arthur Jones and his company and a crew of HIT advocates, the principles and concepts of HIT became popularized.
HIT workouts usually include one set of one or two exercises per muscle group, performed to the point of momentary muscle failure. The recommended repetition ranges vary, with most being from as low as 3-5 to as high as 15-20. Lower repetition ranges are often recommended for upper body exercises, while higher repetition ranges are often recommended for the lower body, lower back, abs, and neck.
The recommended repetition speeds are often relatively slow, but not always Super Slow. Nautilus inventor Arthur Jones originally recommended a 2/1/4 cadence; a two-second positive movement, a one-second hold at the end point, and a four-second negative. Later, Jones, Mike Mentzer, and others would recommend performing the positive more slowly, reducing the cadence to 4/1/4 or 4/2/4. Some HIT methods involve even slower repetition cadences, like Ken Hutchins' SuperSlow, with a ten-second positive, ten-second negative, and a two to three-second hold at the end point on some compound pulling and simple movements, but not compound pushing movements, and Ellington Darden PhD's 30/30/30 method, consisting of a 30-second negative, a 30-second positive, and another 30 second negative.
HIT stresses intensity over repetition. Many weightlifters will use a HIT routine to help break a 'plateau' - meaning they will use HIT temporarily when another routine stops giving desired results. Some HIT trainees will use HIT exclusively as well - Arthur Jones believed HIT was all that was required.
Different strength training authors from Ellington Darden and Mike Mentzer to Dorian Yates and Gordon LaVelle have called their system HIT, with each individual having credited Arthur Jones for the formulation of its basic tenet principles. However, there has never been a clear and consistent guideline on how to utilize HIT. Darden advocated full body routines, while Yates recommended to split the workouts into four different sessions a week. Mentzer believed that no more than one set to muscular failure per body part was all that was required, [5] yet Yates and LaVelle believed that more than one exercise per body part is necessary to get complete development as a bodybuilder.
A former Mr. Universe, the late Mike Mentzer achieved his lifetime best condition from performing rest-pause, an old system of lifting involving single-rep maxima interspersed with brief (10 second) rest periods. [6] Rest-pause has the advantages of old-school power training while also allowing for enough overall reps to be performed for hypertrophy and cardiovascular exercise purposes.
Mike Mentzer was an American IFBB professional bodybuilder, businessman and author.
Calisthenics or callisthenics (/ˌkælɪsˈθɛnɪks/) is a form of strength training consisting of a variety of movements that exercise large muscle groups, such as standing, grasping, pushing, etc.
The bench press, or chest press, is a weight training exercise where a person presses a weight upwards while lying horizontally on a weight training bench. Although the bench press is a full-body exercise, the muscles primarily used are the pectoralis major, the anterior deltoids, and the triceps, among other stabilizing muscles. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
Bicep curls are a group of weight training exercises in which a person bends their arm towards their body at the elbow in order to make their biceps stronger.
Body for Life (BFL) is a 12-week nutrition and exercise program, and also an annual physique transformation competition. The program utilizes a low-fat high-protein diet. It was created by Bill Phillips, a former competitive bodybuilder and previous owner of EAS, a manufacturer of nutritional supplements. It has been popularized by a bestselling book of the same name.
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve strength and endurance. It is often associated with the lifting of weights. It can also incorporate a variety of training techniques such as bodyweight exercises, isometrics, and plyometrics.
A squat is a strength exercise in which the trainee lowers their hips from a standing position and then stands back up. During the descent, the hip and knee joints flex while the ankle joint dorsiflexes; conversely the hip and knee joints extend and the ankle joint plantarflexes when standing up. Squats also help the hip muscles.
High-intensity interval training (HIIT) is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion. HIIT involves exercises performed in repeated quick bursts at maximum or near maximal effort with periods of rest or low activity between bouts. The very high level of intensity, the interval duration, and number of bouts distinguish it from aerobic (cardiovascular) activity, because the body significantly recruits anaerobic energy systems. The method thereby relies on "the anaerobic energy releasing system almost maximally".
A resistance band is an elastic band used for strength training. They are also commonly used in physical therapy, specifically by convalescents of muscular injuries, including cardiac rehab patients, to allow slow rebuilding of strength.
Plyometrics, also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping. Plyometrics are primarily used by athletes, especially martial artists, sprinters and high jumpers, to improve performance, and are used in the fitness field to a much lesser degree.
One-repetition maximum in weight training is the maximum amount of weight that a person can possibly lift for one repetition. It may also be considered as the maximum amount of force that can be generated in one maximal contraction.
In weight training, training to failure is repeating an exercise to the point of momentary muscular failure, i.e. the point where the neuromuscular system can no longer produce adequate force to overcome a specific workload. Two systematic reviews published in 2021 found no benefit to training to failure on hypertrophy, while one of the reviews found some evidence that not-to-failure training is superior for strength.
Ray Mentzer born in Philadelphia was the 1976 Junior Mr. America, 1978 IFBB Mr. USA and was winner of the 1979 Mr. America competition. Ray's brother, Mike Mentzer won the rival IFBB Mr. America in 1976 during Ray's Junior title.
Circuit training is a form of body conditioning that involves endurance training, resistance training, high-intensity aerobics, and exercises performed in a circuit, similar to high-intensity interval training. It targets strength building and muscular endurance. An exercise "circuit" is one completion of all set exercises in the program. When one circuit is completed, one begins the first exercise again for the next circuit. Traditionally, the time between exercises in circuit training is short and often with rapid movement to the next exercise.
Super Slow is a form of strengthening physical exercise popularized by Ken Hutchins. Super Slow is Hutchins' trademarked name for the High intensity training approach advocated by Arthur Jones. It is based on ideas from the 1940s and 1960s called 10/10 "muscle contraction with measured movement" and implemented using fixed weight Nautilus machines. In more recent times, such "Time Under Load" ideas have seen a renaissance with Dr Doug McGuff's best selling Body by Science.
Progressive overload is a method of strength training and hypertrophy training that advocates for the gradual increase of the stress placed upon the musculoskeletal and nervous system. The principle of progressive overload suggests that the continual increase in the total workload during training sessions will stimulate muscle growth and strength gain by muscle hypertrophy. This improvement in overall performance will, in turn, allow the athlete to keep increasing the intensity of their training sessions.
Ballistic training, also incorrectly referred to as power training, is a form of training which involves throwing weights, and jumping with weights, in order to increase explosive power. The term ballistic refers to a method of training, where the athletes' body or an external object is explosively projected into a flight phase [31] and can, therefore, include exercises such as jumps, throws, or strikes. The intention in ballistic exercises is to maximise the acceleration phase of an object's movement and minimise the deceleration phase. For instance, throwing a medicine ball maximises the acceleration of the ball; this can be contrasted with a standard weight training exercise where there would be a pronounced deceleration phase at the end of the repetition i.e. at the end of a bench press exercise the barbell is decelerated and brought to a halt. Similarly, an athlete jumping whilst holding a trap bar maximises the acceleration of the weight through the process of holding it whilst they jump; where as they would decelerate it at the end of a standard trap bar deadlift.
The Colorado Experiment was a bodybuilding experiment run by Arthur Jones using Nautilus equipment at the Colorado State University in May 1973.
Street workouts are a physical activity performed in outdoor parks or public facilities. The movement behind street workouts became popular in Russia, Israel, Myanmar, Morocco, Eastern Europe, and the United States, especially in New York City, Los Angeles, Chicago, Philadelphia, Miami, Baltimore, Washington, D.C., and other urban East Coast neighborhoods. It is a combination of athletics, calisthenics, and sports. "Street workout" is a modern name for calisthenics in outdoor parks. There are also street workout teams and organized competitions for exercises such as pull-ups, chin-ups, push-ups, dips, rows, muscle-ups, sit-ups and squats. A street workout also involves static (isometric) holds such as the human flag, front lever, back lever, L-sit and planche.
German Volume Training (GVT), commonly referred to as the "10x10 workout", is a form of weight training. It employs high set counts and moderate repetitions. GVT workouts typically involve 10 sets of 10 repetitions focused on a specific muscle group.
