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. [1] [2] 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. [3] [4]
When the athlete has reached initial failure (i.e. fails to perform a further repetition), rather than ending the current set, the exercise can be continued by making the exercise easier (switching to another similar exercise e.g. pull-ups to chin-ups, switching to another (correct) form of the same exercise, switching to lower weight) or by recruiting help (from a spotting partner or by involving another body part). The athlete may also choose to use the rest-pause method or other advanced techniques.
A repetition maximum (RM) is the maximum weight a person can lift for the indicated number of repetitions. For example, a 10RM is the weight at which a person can do 10 lifts, but fail to fully perform the 11th. Similarly, a 1RM, or one-repetition maximum, is the most a person can fully lift (at least) once.
Determining a repetition maximum must be done to true failure – by definition, it represents the weight and repetition count at which the person reaches failure, and can no longer lift. Therefore, this also can be considered a form of training to failure. Though 1RM is the most popular and commonly used, any number of repetitions can be used, such as 10RM or 15RM.
A 10RM weight is more useful in terms of training for hypertrophy than a 1RM. [5] There is less consensus as to why a 10RM is actually safer; it may be because a 10RM can be performed with a much lower risk of joint injury (due to the lower weight), [6] but also potentially because failure occurs due to absolute inability of the muscles to perform at the attempted weight (rather than due to fatigue). [7]

There are multiple types of failure [8] [9] that can be reached before ending a set. They are listed here in order of increasing intensity.
When determining repetition maximum, form failure should be used. Training past form failure can cause joint and muscle injury and should never be attempted. Beginners should train to pre-failure or tempo failure, while focusing on maintaining proper form.
Powerlifting is a strength sport that consists of three attempts at maximal weight on three lifts: squat, bench press, and deadlift. As in the sport of Olympic weightlifting, it involves the athlete attempting a maximal weight single-lift effort of a barbell loaded with weight plates. Powerlifting evolved from a sport known as "odd lifts", which followed the same three-attempt format but used a wider variety of events, akin to strongman competition. Eventually, odd lifts became standardized to the current three.
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 compound movement, 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.
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.
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.
An isometric exercise is an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words isos (equal) and -metria (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. This is in contrast to isotonic contractions, in which the contraction strength does not change, though the muscle length and joint angle do.
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.
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.
A negative repetition is the repetition of a technique in weight lifting in which the lifter performs the eccentric phase of a lift. Instead of pressing the weight up slowly, in proper form, a spotter generally aids in the concentric, or lifting, portion of the repetition while the lifter slowly performs the eccentric phase for 3–6 seconds.
Complex training, also known as contrast training or post-activation potentiation training, involves the integration of strength training and plyometrics in a training system designed to improve explosive power. According to Jace Derwin:
Strength training and plyometric training are both effective measures for increasing athletic performance independent of each other, but a true program designed for power-based athletes needs to incorporate both disciplines. A study done in 2000 in the NSCA's Journal of Strength and Conditioning Research measured three different training protocols: strength training, plyometric training, and a combination of both. The group that used combined methods was the only group that showed significant increases in BOTH strength and power.
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.
Muscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril size. It is the primary focus of bodybuilding-related activities.
In bodybuilding and weight training, using drop sets is a technique for continuing an exercise with a lower weight once muscle failure has been achieved at a higher weight. It is most often performed on weight machines because reducing the weight quickly is thought by some to be extremely important, but it can also be performed with dumbbells and other free weights.
Eccentric training is a type of strength training that involves using the target muscles to control weight as it moves in a downward motion. This type of training can help build muscle, improve athletic performance, and reduce the risk of injury. An eccentric contraction is the motion of an active muscle while it is lengthening under load. Eccentric training is repetitively doing eccentric muscle contractions. For example, in a biceps curl the action of lowering the dumbbell back down from the lift is the eccentric phase of that exercise – as long as the dumbbell is lowered slowly rather than letting it drop.
Weightlifting or weight lifting generally refers to physical exercises and sports in which people lift weights, often in the form of dumbbells or barbells. People engage in weightlifting for a variety of different reasons. These can include: developing physical strength; promoting health and fitness; competing in weightlifting sports; and developing a muscular and aesthetic physique.
Blood flow restriction training / Occlusion Training or Occlusion Training or KAATSU is an exercise and rehabilitation modality where resistance exercise, aerobic exercise or physical therapy movements are performed while using an Occlusion Cuff which is applied to the proximal aspect of the muscle on either the arms or legs. In this novel training method developed in Japan by Dr. Yoshiaki Sato in 1966, limb venous blood flow is restricted via the occlusion cuff throughout the contraction cycle and rest period. This result is partial restriction of arterial inflow to muscle, but, most significantly, it restricts venous outflow from the muscle. Given the light-load and strengthening capacity of BFR training, it can provide an effective clinical rehabilitation stimulus without the high levels of joint stress and cardiovascular risk associated with heavy-load training.
Power training typically involves exercises which apply the maximum amount of force as fast as possible; on the basis that strength + speed = power. Jumping with weights or throwing weights are two examples of power training exercises. Regular weight training exercises such as the clean and jerk and power clean may also be considered as being power training exercises due to the explosive speed required to complete the lifts. Power training may also involve contrasting exercises such as heavy lifts and plyometrics, known as complex training, in an attempt to combine the maximal lifting exertions with dynamic movements. This combination of a high strength exercise with a high speed exercise may lead to an increased ability to apply power. Power training frequently specifically utilises two physiological processes which increase in conjunction with one another during exercise. These are deep breathing, which results in increased intra-abdominal pressure; and post-activation potentation, which is the enhanced activation of the nervous system and increased muscle fibre recruitment. Power training programmes may be shaped to increase the trainee's ability to apply power in general, to meet sports specific criteria, or both.
Velocity based training (VBT) is a modern approach to strength training and power training which utilises velocity tracking technology to provide rich objective data as a means to motivate and support real-time adjustments in an athlete's training plan. Typical strength and power programming and periodisation plans rely on the manipulation of reps, sets and loads as a means to calibrate training stressors in the pursuit of specific adaptations. Since the late 1990s, innovations in bar speed monitoring technology has brought velocity based training closer to the mainstream as the range of hardware and software solutions for measuring exercise velocities have become easier to use and more affordable. Velocity based training has a wide range of use cases and applications in strength and conditioning. These include barbell sports such as powerlifting and Olympic weightlifting and Crossfit, as well as rock climbing.Velocity based training is widely adopted across professional sporting clubs, with the data supporting many periodisation decisions for coaches in the weight room and on the field.
