If you’re asking when did strength and conditioning start, the clearest answer is that its modern, organized form took shape in the 20th century, especially from the 1960s onward. Physical training for strength is far older, but the profession of preparing athletes through planned strength and fitness programs developed much later.
This history can be confusing because people use “strength and conditioning” to describe both ancient exercise and modern sports science. Here, you’ll see how those traditions connect, what changed in the 20th century, and why coaches began treating athletic preparation as a specialized discipline.
when did strength and conditioning start?
Strength and conditioning as a modern athletic profession emerged during the 20th century. Its roots reach further back, but the organized system familiar today—coaches planning strength, speed, power, and conditioning around athletic performance—grew notably in the 1960s and 1970s.
There is no single inventor or universally accepted start date. Athletes had trained to become stronger for centuries, and physical educators and medical practitioners developed training methods before modern sports teams hired dedicated strength coaches. The key distinction is between the long history of physical training and the more recent creation of a formal profession.
In the United States, the University of Nebraska’s strength program under Boyd Epley, begun in 1969, is often cited as an important milestone in collegiate strength coaching. The National Strength and Conditioning Association (NSCA), founded in 1978, helped give the growing field a professional organization. Those milestones mark the development of the modern discipline, not the beginning of strength exercise itself.
Strength training existed long before the modern profession
People have used physical challenges to build strength and prepare for work, combat, and sport throughout recorded history. Ancient Greek athletes, for example, trained for athletic contests with forms of resistance exercise. Accounts from antiquity also describe lifting stones and other heavy objects, although some famous stories about particular feats may be legendary rather than verifiable history.
Physical preparation was not always separated from everyday life. Farming, construction, carrying supplies, and military training required strength and stamina. In many societies, people developed these qualities through labor or practical drills rather than through a carefully designed sports program.
As organized sport expanded, more athletes and educators became interested in training specifically for performance. Gymnastics, wrestling, weightlifting, and other activities helped popularize structured exercise. Yet early programs did not always use today’s concepts of exercise prescription, recovery, or sport-specific planning.
Physical culture brought exercise into organized settings
During the 19th and early 20th centuries, physical culture movements encouraged people to exercise for health and strength. Gymnasiums, schools, clubs, and training halls offered more regular access to equipment and instruction. Dumbbells, barbells, and other resistance tools became more familiar parts of exercise.
Some physical educators began applying measurement and planned exercise to physical education. This helped shift training from occasional effort toward repeatable practice. Even so, the work was not yet a unified strength-and-conditioning profession. School physical education, bodybuilding, rehabilitation, and competitive sport often developed along separate paths.
What changed in the 20th century?
The modern field formed as sport became more organized and coaches sought reliable ways to improve performance. A stronger understanding of exercise physiology, biomechanics, and recovery gave trainers a clearer basis for choosing and adjusting training. Teams also began to recognize that athletes could benefit from preparation beyond sport practice alone.
One important change was the use of planned resistance training as part of athletic preparation. Instead of assuming that lifting weights would automatically make an athlete slower or less skilled, coaches could select exercises and training loads to develop qualities such as strength and power. The program could then be coordinated with sport practice and competition.
Another change was the use of progressive training. This means gradually adjusting the challenge as an athlete adapts, rather than repeating the same effort indefinitely. Progression can involve changes to load, repetitions, exercise difficulty, or rest. It gives training a structure and makes it easier to respond to an athlete’s needs.
Rehabilitation also influenced thinking about resistance exercise. In the 1940s, physician Thomas DeLorme helped develop a progressive resistance approach for rebuilding muscle strength. That work was directed toward rehabilitation rather than team sport, but it reflected a wider shift toward systematic, measurable exercise. The same broad principle—adjusting resistance to support physical adaptation—became useful in athletic training.
Milestones in the development of strength and conditioning
| Period or milestone | What developed | Why it matters | Best understood as |
|---|---|---|---|
| Ancient and premodern eras | Strength and endurance developed through sport, work, and physical challenges | Shows that physical preparation predates modern gyms and sports science | Early training practices |
| 19th and early 20th centuries | Gymnasiums and physical culture made organized exercise more visible | Helped establish exercise as a planned activity outside daily labor | Early organized fitness |
| 1940s | Progressive resistance methods gained attention in rehabilitation | Supported more systematic approaches to rebuilding strength | A related scientific influence |
| 1960s and 1970s | Dedicated athletic strength programs became more established, including collegiate programs | Marked the growth of strength coaching as a specialized role | Modern professional development |
| 1978 | The NSCA was founded | Provided a professional organization for strength and conditioning practitioners | Formal recognition and community |
The dates in this table are landmarks, not a claim that every team changed at once. The profession grew through many coaches, schools, researchers, and organizations, with adoption varying by sport and country.
How strength and conditioning became a distinct job
For much of sports history, the head coach or sport coach handled nearly every part of preparation. As training programs became more detailed, teams increasingly needed people focused on physical development. A dedicated coach could plan resistance exercise, monitor workload, and help athletes build qualities that sport practice might not develop efficiently on its own.
Collegiate programs helped establish this model. Nebraska’s program under Boyd Epley is frequently recognized as a pioneering example of a dedicated strength program in college athletics. Its significance lies not in creating the idea of strength training, but in helping show that strength coaching could be a defined role within a sports department.
The NSCA’s founding in 1978 offered practitioners a shared professional home. Organizations like this supported education, professional exchange, and the spread of common training principles. Over time, the work expanded across colleges, professional teams, schools, private facilities, and other sports settings.
As the role developed, strength coaches worked more closely with sport coaches, athletic trainers, and medical staff. This collaboration matters because athletic preparation must account for practice demands, injuries, travel, and competition schedules. A training plan that ignores those factors can add fatigue instead of helping performance.
How sports science shaped modern training
Strength and conditioning grew alongside research into how the body responds to exercise. Coaches learned to distinguish between different physical qualities, such as maximal strength, muscular endurance, speed, and power. These abilities overlap, but they are not interchangeable. Training needs to match the quality an athlete is trying to improve.
Coaches also became more deliberate about the relationship between training and recovery. Exercise creates a stimulus, but the body needs time to adapt. Too little challenge may not produce the desired change; too much, especially when combined with a heavy competition schedule, may leave an athlete fatigued or at greater risk of injury.
Periodization is one term that emerged in organized training. It describes planning training in phases over time, with changes in emphasis, intensity, or volume. The purpose is to prepare an athlete for the demands of competition while managing training stress. Periodization is a planning tool, not a guarantee of success, and its details should fit the athlete and sport.
Training also became more specific. A basketball player, a distance runner, and a weightlifter need different physical qualities and schedules. A sound program develops relevant qualities without trying to make every athlete follow the same exercises or workload.
What strength and conditioning means today
Today, strength and conditioning refers to planned physical training that supports athletic performance and general physical preparedness. A program may include resistance exercise, sprinting, jumping, change-of-direction work, aerobic conditioning, mobility, and recovery practices. The mix depends on the sport, training age, health, and goals of the athlete.
Strength training is one part of conditioning, not a synonym for the entire field. Conditioning can refer to developing the ability to sustain or repeat effort, while strength work focuses on producing force against resistance. In practice, these qualities can overlap, and a well-designed program often addresses several of them.
Modern coaches may use performance tests and training records to guide decisions. Measurements can help track progress, but they do not replace coaching judgment. A test is useful only if it answers a relevant question and its results are interpreted in context.
The field now includes both elite sport and general fitness. A professional athlete may need a tightly coordinated plan around competition, while a recreational athlete may focus on basic strength, movement skills, and steady conditioning. The underlying principles can be similar, but the program should reflect the person’s circumstances.
Common misconceptions about the history
There is no single date when the field began
People often ask for one exact year, but the answer depends on what they mean by “started.” Resistance exercise is ancient. Organized physical education developed much later, and dedicated strength coaching in modern sport became more recognizable in the 20th century. The 1960s and 1970s are useful markers for professional development, not a precise birthday for the entire field.
Ancient lifting was not the same as modern sports science
It is fair to say that ancient athletes trained for strength. It is misleading to describe their methods as a modern strength-and-conditioning system. Today’s field draws on planned exercise, sport-specific goals, coaching practice, and scientific knowledge that developed over many centuries.
Strength and conditioning is broader than weightlifting
Resistance training is important, but it is not the whole discipline. A program may also develop speed, aerobic fitness, jumping ability, movement control, and the capacity to recover between efforts. Treating strength work as the only component can leave an athlete underprepared for the actual demands of a sport.
A milestone does not mean everyone adopted the method immediately
The creation of a college program or professional association signals growing recognition, not instant change across all sports. Teams adopt methods at different times, and training practices continue to evolve. Historical accounts are clearest when they distinguish a widely recognized milestone from a universal turning point.
Why this history matters to athletes and coaches
Knowing the history helps explain why modern training combines experience with evidence. The field did not appear fully formed; coaches refined practices as sport demands, equipment, and scientific knowledge changed. That process is still underway.
It also helps correct a common assumption: older exercise is not automatically better or worse than newer exercise. A method is useful when it fits the goal, the athlete, and the demands of the sport. The age of an exercise alone does not show whether it belongs in a program.
For athletes, the practical lesson is to look for a plan with a clear purpose and progression. Ask what quality each exercise is meant to develop, how the workload fits with practice, and how progress will be monitored. If the answer is simply “because athletes have always done it,” the reasoning may need a closer look.
For coaches, the historical record points to the value of coordination. Physical training works best when it complements sport practice and considers recovery, skill development, and health. Stronger athletes are not produced by adding the most possible work; they are developed through training that is appropriate and sustainable.
The short answer to when did strength and conditioning start is that physical training is ancient, while the modern profession took shape mainly in the 20th century. The growth of dedicated athletic programs in the 1960s and 1970s, followed by the NSCA’s founding in 1978, helped establish the field.
To apply that history, focus on the purpose behind a training plan rather than its age or popularity. Before your next session, identify the physical quality you want to improve and make sure the exercise, workload, and recovery support that goal.
