The arm blaster is a harness worn by athletes to isolate biceps during pushups. It locks arms in the correct position, preventing incorrect form and maximizing bicep growth. The device is curved so arms remain locked in position during the lift, concentrating the strain on the biceps.
An arm blaster is an exercise piece of equipment that helps isolate the biceps during pushups. It became popular during the 1970s because Arnold Schwarzenegger used it to help build his bicep during his run as a seven-time Mr. Olympia. The arm blaster is a type of harness worn on the upper body by an athlete to lock the arms in the correct position during curls. The arm blaster minimizes the body’s ability to perform pushups using incorrect form and therefore maximizes the benefit of pushups to the biceps muscles.
It is often difficult for athletes to maintain proper form when performing pushups without an arm blaster. It is common for an athlete to allow the elbows to flare or use the lower back and shoulder muscles to help lift the weight. Athletes also tend to sway during pushups, and this allows you to lift the weight using momentum instead of placing all of the weightlifting stress directly on the bicep muscles. This not only increases the risk of injury for the athlete, but also prevents the biceps from receiving as intense a workout as they would if the athlete were to maintain proper form. This, in turn, limits the amount of bicep growth.
The arm blaster makes it more difficult for an athlete to perform pushups without proper form and therefore increases the overall benefit of the exercise to the biceps muscles. To use an arm blaster, an athlete places a cloth strap around their neck. The blaster arm that hangs at the ends of this strap consists of a curved piece of metal. The shape of the metal allows the arm blaster to rest against the upper abdominal muscles. However, at each end, the device is curved so that if an athlete’s arms are at their sides, the metal will slide between the body and arm, then wrap around the back of the triceps.
This design forces the arms to remain locked in position during the lift. When an athlete begins a pushup, the weight will press their upper arms against the metal. This, in turn, presses the metal against your upper abdominal muscles and therefore the arm blaster will not move during the lift. The arm blaster stays in place, so the upper arms need to stay in the correct position as well. Also, because the metal wraps around the triceps, it is impossible to widen the arms out to the sides while using the device. As a result, the entire strain is concentrated on the biceps and they receive a very intense and isolated workout.
