The unknown 10/12 Method for Strength Training at Home. Strength training for women and men with the Exer-Genie® is simple, but not easy: An exercise begins with a 10-second isometric contraction, thereby fatiguing the muscle, then the isotonic phase takes over by working through a range of some particular sport-specific motion. For football, it may be a passing movement for the quarterbacks, forearm motion for the linemen, or leg, knee, or foot motion for all. 3 reps of 22 seconds each add up to 66 seconds full contraction time for the muscle groups addressed by the particular exercise. F.e. 5 exercises with a duration of 3 Minutes each (giving you over 30 seconds rest and preparation time for the next rep) can be done within 15 Minutes adding up to 330 seconds full contraction time (TUT: Time Under Tension). All in your living room! The amount of resistance or weight from the Exer-Genie® is controlled by a little lever on the handle, it ranges from 0 to around 400 pounds. And the best: Exer-Genie® fits in a small pocket and is the perfect tool for strength training at home.

The Exer-Genie® Exerciser was developed in 1961. The American Space Program was experimenting with “Fitness in Space” when a variable resistance rope friction device which was originally designed to lower people from a burning building (Sky-Genie Controlled Descent Device) was adapted to a small exercise machine and named Exer-Genie® Exerciser. It was the first all-in-one Muscle Movement Training System that allowed the application of multiple concepts of exercise through a range of motion. The Exer-Genie® Exerciser is in the Official Navy Seal Physical Fitness Guide (August 1997 & 2007), has graced the gyms of World Class Coaches and Trainers, and has been the secret weapon for Champions in every sport. Coach Vince Lombardiʼs Green Bay Packers used the Exer-Genie® Exerciser so effectively that every team and every champion for the past 50 years has followed the leader. Exer-Genie® is the original Portable Variable Resistance Trainer.


In testing the Exer-Genie® Exerciser, Scientists, Researchers and Coaches discovered that resistance was generated by winding the specially woven nylon training line around the smooth chrome-plated metal shaft. Adjusting the resistance was easy and in a few seconds, one could go from ounces to hundreds of pounds. Pulling on the training line not only controlled the speed at which a movement was trained, but also provided resistance that was proportional to the kinetic chain of the movement. Dynamic Life Movement Exercise was a major discovery! Training muscles through the movement equaled greater performance and Efficiency in Exercise™.

This was proof that the Exer-Genie® Exerciser provided an economical and efficient way to perform a variety of exercises and training methods. One breakthrough training discovery that came out of the testing was the Variable Isokinetic Exercise. By grasping the trailing end of the line and controlling the movement of the Trailing Line through the Exer-Genie® Exerciser, one could implement Variable Isotonic/Isometric/Isokinetic Training.

  • Isotonic Muscular contractions are those movements based on lifting a constant amount of weight through a range of motion.
  • Isometric Muscular contraction against resistance is where the muscle fires but there is no shortening of the muscle and no movement at a joint. The benefit of isometric exercises is that they can be used for rehabilitation as well as general strengthening without placing stress on the joints. Some sports require a high level of static muscle strength; Gymnastics, Yoga, Rock Climbing, Downhill Skiing as well as holding a child, for example, all have isometric strength requirements.
  • Isokinetic Muscular contraction pertains to an exercise providing variable resistance to a movement at a constant speed with the assistance of specialized equipment. In isokinetic exercise, you maximize the resistance placed on the muscle throughout the full range of motion. The benefit of Isokinetic Exercise is the ability to train movements not just muscles. This type of training allows for greater strength, flexibility, and elasticity gains more efficiently than training one muscle at a time.

At the time the Exer-Genie® Exerciser was being developed, experiments were being conducted by many exercise Physiologists, Trainers, and Coaches throughout the United States, Canada, and the world over on the application of the Exer-Genie® Exerciser for injury prevention, functional training, and functional performance enhancement.

The Exer-Genie® Exerciser provided for the first time in the history of exercise a practical, economical, efficient, and highly effective way for anyone at any age to get fit and stay fit. Our program has been used by thousands of High Schools and Colleges, Rehab Clinics, Functional Training Centers, Sports Performance Centers, and hundreds of thousands of individuals looking to improve their Functional Fitness and Performance. Professional Teams such as the Green Bay Packers, Dallas Cowboys, Minnesota Vikings, Seattle Seahawks, Oakland Raiders, San Diego Chargers, Golden State Warriors, and many others have made the Exer-Genie® Exerciser an integral part of their Functional Training and Injury Prevention Programs.

With the use of Space Age Materials and the newest design techniques the highly publicized Exer-Genie® Exerciser has been improved and is widely known simply as Exer-Genie®. The improved model uses high-impact, high-temperature-resistant plastic for the casing. An improved resistance dialing mechanism allows the unit to adjust from ounces to hundreds of pounds of resistance and back in a matter of seconds. With the improvement in construction and design comes a new formula in the training line. A scientifically woven nylon training line allows for smooth operation at any resistance setting with exceptional durability.

We built the first Exer-Genie® in 1961 and for over 60 years we have taken pride in remaining committed to supporting the ingenuity, spirit of workmanship, and product integrity that is uniquely American.

1961: The Exer-Genie® Exerciser was developed as a way to allow astronauts to train for missions and to exercise while in space. NASA was attracted by the lightweight and small size of the Exer-Genie® Exerciser and decided to put the exercise concept to the test to see if it could provide a valid method for exercising astronauts in microgravity. Using the Lockheed Human Performance Laboratory in Sunnyvale, California, NASA scientists put the Exer-Genie® Exerciser through a series of extensive studies based around Isometrics, Isokinetics, Isotonics, Variable Resistance and Resistive Aerobics. They found the unit to be extremely effective in conditioning muscle fiber and maintaining bone mass in microgravity.

1964: The Exer-Genie® Exerciser was recognized as a breakthrough in the theory of combining isometric and isotonic exercise. The simplicity of accomplishing isomeric contraction by fingertip pressure to fatigue the muscle, and then working the tired muscle isotonically through the full range of motion, made the Exer-Genie®exerciser ideally suited for this theory as well as other theories of exercise. Strength, endurance, flexibility, and technique can be developed in minimum time, reducing repetition and boredom. In 2008 that system became known as The Trainer Custom Series Exer-Genie® Exerciser. From there the Exer-Genie® went through a lot of amazing advances and experiments including being part of Nasa’s astronaut program and playing a big role in keeping the astronauts fit for their 500,000-mile journey into space on Apollo 7, 8 which orbited the moon 10 times, as well as on the Apollo 11 flight to the moon. The Exer-Genie® also excelled in the sports world and was accepted by thousands of schools, colleges, and professional teams as well as Olympic athletes. By allowing the motion of the sport to be simulated against selected resistance and uniform through a complete range of motion, the Exer-Genie® became a must-have for all sports enthusiasts.

1965: Green Bay Packers become the first NFL team to use Exer-Genie® as part of their training regimen. Within a couple of years, the system is being used by many more including the Cleveland Browns and Dallas Cowboys.

1968: Exer-Genie® is used to train the astronauts who will orbit the Earth in the first manned mission in the United States Apollo space program (Apollo 7) as well as the crew who orbited the moon 10 times in December of that year (Apollo 8).

1968, August 26: Exer-Genie® has become so popular with college teams, NFL teams, MLB teams, and home consumers, that it receives a feature article in Sports Illustrated.

1969: Exer-Genie® helps prepare the first men who will set foot on the moon on July 20, 1969. It also joins them on their journey into space to give them a way to work out while on the Apollo 11 mission

1974 & 1975: NHL team Philadelphia Flyers win back-to-back Stanley Cups while training with the Exer-Genie®

1989: The Trainer® Fitness & Rehab System was developed for the non-athlete using the Exer-Genie® exerciser’s technology along with 36 years of research and application for the busy person looking to take better care of themselves. It is the answer to the 5 problems in exercise. Time, Boredom, Soreness, Convenience, Staying With It. Starting with 2 minutes a day you make taking care of the most valuable asset you have (your body) a habit. The instructional material has been developed to make physical conditioning and shaping up safe, simple, and effective in the time spent. Team America Health & Fitness purchased the Exer-Genie® and Team America soon appointed Jim Warren as the National Director. Jim has worked with an Exer-Genie® since 1971 and now with a Degree in Physical Education from the University of Northern Illinois, Grad work at the University of North Texas, and with his extensive knowledge in Fitness and business development, Jim Warren decided to take the reigns of the business. Team and Jim Warren upgraded the Exer-Genie® to The Trainer Custom Series Exer-Genie® Exerciser and made a few changes to the device allowing it to operate smoother and more efficiently. The Trainer Custom Series Exer-Genie® is still in high demand and is considered one of the most essential and best-kept secrets in personal training.
