Bullworker Isometric Information

This is the place to come to find any and all information regarding the Bullworker family of exercise devices.

The Bullworker is available in many forms from the early days when it was known as a Tensolator to the latest incarnation of the Bullworker X5. The Bullworker is the original isometric fitness system and has been updated slightly with minor model changes through the years.

They say that plagiarism is the greatest form of flattery so this must prove its a great product. There are many replica and copycat products on the market from slightly modified devices like the Muscle Gun, Fitness Bar, Steel Bow or the Exxerwatch down to the flagrant rippof's that try and associate themselves with the quality and reputation of Bullworker; products such as the Powerworker, Pitbull, Xtreme and Buffalo Worker are all cheap clones and not the real thing. [All these products work on the same principle as the Bullworker but quality of construction varies greatly... as do the some of the wild claims!]
