The legendary bicep training device that boosts their development by isolating the influence of other muscles and specializing the exercise load exclusively on the bicep flexors. It keeps the elbows close to the torso and prevents "cheating" with the waist and shoulders. The Viking Arm Blaster is of exceptional quality as it is made of steel and lined with EVA protective material at the points where it comes into contact with the body. It is fully functional with progressive "curves" that embrace the body and serve as locking points for the elbows.
