Bullworker

Bullworker

Marketed and sold worldwide for more than 50 years, the Bullworker has remained one of the best tools for isometric exercise to be found.  

The Bullworker features two different models: the Bow Classic and the Steel-Bow, each retailing for around $150. The two bows differ in length, power, and range of motion.  The classic model measures 36 inches in length and specializes in greater range of motion and powerful holds, while the Steel-Bow is 20 inches long and is good for targeting muscles and travels well. 

The Bows feature interchangeable springs that alter the level of resistance which ranges from 0 to 130 pounds. 

Designed around the concept of Isometric Exercise, the Bullworker employs a type of strength training wherein the joint angle and muscle length remain stagnant during the entire contraction which is held for a specific length of time. 

Rather than a dynamic exercise that takes you through a range of motion, isometrics remain static. However, the Bullworker fitness regimen incorporates isotonic, resiliency, iso-motion, cardio, and endurance routines. 

Providing a convenient way to improve strength and flexibility, the Bullworkers may be purchased individually or as a Complete Cross Training home gym pro pack, which functions as a complete cross-training home workout regimen.

The full product line retails for around $330 and includes the two bullworkers, 3 springs for varied resistance, a carrying case, a non-slip pad, the Iso-Gym and Iso-Bow manuals with 90-day routines, and instruction chart. 

How the Bullworker Came to Be

After concluding that muscle-growth can be attained at a more rapid rate by exerting existing muscle strength against stronger resistance for a length of 7 seconds, the concept of Isometrics was developed by German scientists Dr. Erich Albert Muller and Dr. Theodor Hettinger. 

The study consisted of more than 200 experiments over a ten year period conducted at the Max Planck Institute, which was then tested at the University of Connecticut by professor James A. Bailey. This study, involving his class of college students, found that isometric training can improve muscle strength, endurance, coordination, and agility three times faster than traditional sports training. 

German inventor Gert F. Kobel then developed the Bullworker which he designed around these findings in the early 1960s. Pioneering the concept of home fitness devices, the Bullworker also brought the benefits of the 7-second isometric hold to the masses at an attainable price.
