Tip: Is This Thing Worth Using?

Arnold used one. Should you? Here's who will benefit the most.


When you curl, the weight moves out in front of your feet and out of your base of support. Long, lanky arms amplify this problem. When the weights get heavy, your focus shifts away from your biceps to stabilizing your body. However, the old-school training accessory called the "arm blaster" fixes the problem.


  • By resting your triceps on the arm blaster, you can focus on flexing your biceps.
  • This gives you similar isolation to preacher curls without the added elbow stress at the bottom and loss of tension at the top.

Tip: Resist the urge to let you triceps move off the arm blaster as you curl the weight up.

Good Alternatives: No arm blaster? No problem! If you have long arms, curl with your back against a wall or do seated dumbbell curls on a back-supporting bench.
