Strength training has long been recognized as a fundamental component of physical fitness, contributing to improved muscle mass, bone density, and a host of other benefits to overall health. Traditional strength training methods, such as dynamic resistance exercises like bench presses and squats, have been the go-to choice for many fitness enthusiasts and athletes. However, recent research* suggests that static, isometric strength training protocols offer unique advantages over their traditional counterparts. In this article, I will delve into the benefits of static, isometric training and provide current, valid, and reliable research to support this stance.

Understanding Isometric Strength Training

Isometric strength training involves the contraction of a muscle without any change in muscle length or joint movement. Essentially, you hold a position for a specified amount of time, creating tension in the muscle without movement. This type of training differs from traditional strength training, where muscles undergo concentric (shortening) and eccentric (lengthening) contractions.

Superiority of Isometric Strength Training:

  1. Time-Efficient Workouts

One of the key advantages of isometric training is its time efficiency. Research published in the Journal of Applied Physiology (2016) found that isometric exercises produced similar strength gains as traditional resistance exercises but required significantly less time. This makes isometric training an excellent choice for individuals with busy schedules.

  1. Reduced Risk of Injury

Traditional strength training methods often involve repetitive movements that can put stress on joints and lead to overuse injuries. Isometric training, on the other hand, minimizes joint movement, making it a safer option. A study published in the Journal of Orthopedic & Sports Physical Therapy (2017) showed that isometric training reduced pain and improved function in individuals with knee osteoarthritis.

  1. Greater Muscle Activation

Research from the European Journal of Applied Physiology (2018) demonstrated that isometric exercises result in greater muscle activation compared to dynamic resistance exercises. This heightened muscle activation can lead to faster strength gains and improved muscle recruitment patterns.

  1. Improved Joint Stability

Static, isometric exercises are effective in enhancing joint stability. A study published in the Journal of Strength and Conditioning Research (2019) found that isometric training improved shoulder stability and reduced the risk of shoulder injuries in overhead athletes.

  1. Versatility

Isometric training can be easily adapted to various fitness levels and goals. Whether you’re a beginner or an elite athlete, isometric exercises can be tailored to meet your specific needs. This versatility is supported by research published in the International Journal of Sports Physical Therapy (2015).

  1. Enhanced Neural Adaptations

Isometric training is known to enhance neural adaptations, improving your ability to recruit motor units and maximize muscle contraction. A study in the Journal of Neurophysiology (2014) reported significant increases in neural drive following isometric training, leading to greater strength gains.

BONUS: Isometric Strength training can have several benefits when it comes to reducing high blood pressure:

  1. Improved Cardiovascular Function: Isometric exercises can help improve cardiovascular health by increasing the workload on the heart. When you perform isometric contractions, your heart has to work harder to pump blood to the muscles being engaged. Over time, this can lead to improved heart efficiency and a reduction in high blood pressure.
  2. Lower Resting Blood Pressure: Regular isometric training has been shown to lead to a decrease in resting blood pressure. This reduction in blood pressure can be particularly beneficial for individuals with hypertension (high blood pressure), as it lowers the risk of heart disease, stroke, and other related health issues.
  3. Increased Vascular Health: Isometric training can enhance the function of blood vessels. It stimulates the release of nitric oxide, a compound that helps relax blood vessels and improve blood flow. This improved vascular function can contribute to the management of high blood pressure.
  4. Reduction in Sympathetic Nervous System Activity: Isometric exercises have been found to reduce the activity of the sympathetic nervous system, which is responsible for the “fight or flight” response. High sympathetic activity can lead to increased blood pressure. By dampening this response, isometric training can help regulate blood pressure.
  5. Stress Reduction: Engaging in isometric exercises can also have stress-reducing effects. Chronic stress is a known contributor to high blood pressure, so activities that help reduce stress can indirectly aid in blood pressure management.
  6. Safe for Various Fitness Levels: Isometric exercises are generally safe for individuals of various fitness levels, including beginners and those with certain physical limitations. They can be adapted to suit individual needs and abilities.

    It’s important to note that while isometric training can be an effective component of a comprehensive approach to managing high blood pressure, it should not be used as the sole method. A balanced approach that includes aerobic exercise, dietary changes, stress management, and regular medical check-ups is typically recommended for the best results. Before starting any new exercise program, especially if you have high blood pressure or other medical conditions, it’s advisable to consult with a healthcare professional to ensure that it’s safe and appropriate for your specific situation.


While traditional strength training methods have their place in fitness routines, current research suggests that static, isometric strength training protocols offer several distinct advantages. These advantages include time efficiency, reduced risk of injury, greater muscle activation, improved joint stability, versatility, and enhanced neural adaptations.

Incorporating isometric exercises into your fitness regimen can provide a fresh perspective on strength training and help you achieve your fitness goals more efficiently and safely. It’s essential to consult with a fitness professional to create a well-rounded program that integrates isometric training appropriately while considering individual needs, goals, preferences and limitations.


The research on the benefits of static and isometric strength training versus traditional methods has evolved over time, and it’s difficult to pinpoint the absolute oldest available research on this topic. However, I can provide some insights into early studies and key developments in this area.

  1. Early 20th Century: Isometric exercises were popularized by Alexander Zass, a strongman and bodybuilder known as “The Amazing Samson,” in the early 20th century. Zass claimed that isometric exercises helped him maintain his strength while he was in captivity during World War I. His personal anecdotes and demonstrations contributed to the initial interest in isometric training.
  2. 1950s-1960s: The work of Dr. John Ziegler, a physician, and Bob Hoffman, the founder of York Barbell Company, played a role in popularizing isometrics in the 1950s and 1960s. Ziegler developed the “iso-ball” and promoted isometric training as an effective method for increasing muscle strength.
  3. 1960s-1970s: Research by Dr. James A. Basmajian and Carlo De Luca in electromyography (EMG) and muscle activation provided valuable insights into the effectiveness of isometric exercises. Their work helped establish a scientific basis for understanding muscle contraction during isometric exercises.
  4. 1970s-1980s: Research studies during this period began to compare the benefits of isometric exercises with traditional isotonic resistance training. Some studies suggested that isometric training could be effective for increasing strength and muscle endurance, while others favored isotonic methods.
  5. 1990s-Present: Over the last few decades, research on strength training methods has become more sophisticated. Studies have explored various aspects of isometric training, including its effects on muscle hypertrophy, strength gains, and injury prevention. Comparisons between isometric and isotonic training methods continue to be a topic of interest among exercise scientists.

While it’s challenging to pinpoint the oldest available research on this topic, it’s clear that the interest in isometric and static strength training has evolved over time. The effectiveness of these methods in comparison to traditional isotonic training depends on various factors, including individual goals, fitness levels, and specific muscle groups being targeted. It’s essential to consult current research and seek advice from fitness professionals to make informed decisions regarding strength training methods.

The above being said, based on my own experiments both recently and throughout my career I highly recommend that people take some time to explore static, isometric training either using a High-End or Lower Cost dedicated device, or by applying the methods outlined in my two part article titled Functional Isometrics Part One. and  Part Two. 

In TNT podcast episode #142 we talk training and especially isometric training with our guest Matt Schifferle from the Red Delta Project. We have actually discussed various forms of static and isometric strength training in at least three of our previous podcast episodes including Episode #20 with Shawn Bennett, #33 with our friend Pete Sisco, and #81 featuring the ViiiV Fitness Motionless Strength Training Machine.
