Bicep isolator5/20/2023 The main thing you have to worry about is ergonomics. You wear the ‘strings’ on your shoulders while the board piece rests on your upper abdominal area, just below your chest. Using an Arm Blaster is luckily pretty simple. This is for the same reason people suggest doing preacher curls for specific short head bicep isolation.Īll in all, though, I think it’s safe to say that the main benefit you will derive from using the Arm Blaster is how much it can improve your form and mind-to-muscle connection, ultimately resulting in superior muscle growth. This is basically when you move your arm in front of yourself.īecause of this function, the short head is hit particularly hard when doing biceps movements with the Arm Blaster, as it forces your arms forward, slightly in front of your body. ![]() I have to note they only became distinctively visible at around 9-10 % body fat.Īnyways, the major difference between the two heads of the biceps is that the short head is heavily involved in the adduction of the humerus (upper arm). I even got caught by surprise at the sight of both heads, as I before my diet had never seen them as two individual entities. Now, if you’re wondering why your biceps might look like a single muscle head, I’ll let you know that most people have to be very, very ripped for visible long and short head separation. The short head is the “inner side” of your biceps, facing inwards towards your torso, while the long head is the “outer side” of your biceps, facing outwards. Your biceps consist of two heads, the long head, and the short head. You only have to worry about your legs and hips – because as they are of course not fixated to anything, it’s still possible to use leg drive to cheat on form to lift more weight or take the set to complete failure. This is a huge benefit of the Arm Blaster – it removes a lot of the movements that aren’t conducive to muscle growth, therefore also allowing you to stress less about keeping good form, and more about establishing the juicy mind-to-muscle connection that we now have hard science telling us improves muscle activation. In practice, this means that most body movement patterns associated with “cheating” on repetitions are removed from the equation of different bicep curl variations. An otherwise common issue that I often experience myself. The art of clean, strict posture biceps movements.īy keeping your elbows and humerus (upper arm) fixed in space relative to your back, individual movement of your arms and your back isn’t possible – unless you insist on extending your arms forward and up.īy fixating these body parts, it’s also more or less impossible to employ any left or right leaning motions with your body.Īdditionally, your arms are not able to flare out doing biceps movements such as dumbbell curls with heavy weights. Today, the Arm Blaster represents an almost lost art form. But that doesn’t explain why gyms don’t have it in their inventory.Īnyways, back in the 1970’s when the Arm Blaster became a stable among the bodybuilders of the golden era of the “sport”, they had their reasons for using it! Ergonomic and technical benefits of the Arm Blaster Why? Not sure – perhaps it’s deemed unpractical. If you wore that in the local Planet Fitness they’d probably kick you out for looming with dangerous meathead aura.īut even in hardcore gyms, such as dark, dusty and spiderweb filled bodybuilding cellars – the Arm Blaster is a very rare sight. I say infamous because this tool of unholy biceps blasting is very, very rarely seen in today’s commercial gyms. But what about the weird piece of equipment strapped to the front of his torso? That’s the infamous Arm Blaster. In conclusion, in terms of safety, it is the hammer curl that far exceeds the bicep curl – though that is not to say that the hammer curl is entirely safe on its own as well.Arnold growing monster biceps with the infamous Arm Blaster. Luckily, this particular injury is rather uncommon and only occurs in exercisers lifting weight in excess of what they would be capable of with proper form. However, in the case of the bicep curl, the usage of improper form or excessive amounts of weight can raise the risk of such conditions as wrist or elbow tendonitis and shoulder impingements from occurring – especially if the exerciser does not perform proper preparatory work such as a mobility routine and adequate warm-ups.Īnother risk presented by the bicep curl but not by the hammer curl is that of a biceps brachii tear wherein the exerciser places excessive stress on the biceps brachii muscle itself and thereby tears its attachment or insertion points at either end of the upper arm – requiring a great deal of rehabilitation and surgery to recover from. ![]() ![]() The bicep curl and the hammer curl are both low impact free weight exercises that place little to no risk of injury on the exerciser’s joint and muscular tissues.
