What is the Arm Blaster? Why use it?
Who wants BIG biceps, strict movement!!!

Originally popularized in the 1970's by none other than seven-time Mr. Olympia Arnold Schwarzenegger, the Arm Blaster is a simple to use device that allows you to better isolate the biceps during all types of curling movements. While building huge biceps is the goal of almost everyone that picks up a weight, most trainees utilize poor form while curling, which usually consists of raising the elbows, swinging the barbell, and/or arching the lower back. Not only can this cause injury, but it also serves to take much of the stress off the biceps, while forcing the shoulders, lower back, and pure momentum to take over. And let me tell you, if you are after greater biceps development, this is a scenario you certainly want to avoid. In order to effectively facilitate muscle growth you must place the greatest stress on the target muscle itself, while minimizing the effort of surrounding muscles. By using the Arm Blaster you will force the elbows and shoulders to remain fixed while performing curling exercises, thus allowing the biceps to do all of the work. This is what you need for maximum biceps hypertrophy!
