Taurus bizeps isolator

Train your upper arms with the biceps isolator like Arnold Schwarzenegger did it once, who is mainly known for his muscular biceps ("Austrian Alps").
The Taurus bizeps isolator is a steel bracket, which hangs around the neck on a shoulder strap and where the elbows are supported. Due to the fixation of the elbows, the Taurus bizeps isolator makes a very isolated training of the upper arms possible. The advantage of this piece of sports equipment is that the shoulders are not involved while doing the exercise and the strength for doing the exercise comes from upper arms exclusively. Thus, both biceps' experience a maximum of stimulation.
Basically, the Taurus bizeps isolator fulfills the same function as a biceps curl pult for weight benches or a Scott bench, though these are much more expensive and are often only found at gyms.
