Arm Blaster Bicep Isolation RDX | Switzerland

The arm blaster is the accessory that forces an absolutely strict curl by physically eliminating any elbow swing. By locking your arms against the aluminium plate, the arm blaster isolates the biceps more effectively than a preacher bench — because the standing position keeps the tension on throughout the movement. It's the bodybuilder's favourite tool for maximising peak biceps contraction. Order before 12:00 for same-day dispatch from Meyrin and delivery in 1 to 2 working days.

The available model

RDX T2 Arm Blaster for biceps curls — thick aluminium plate, adjustable chain strap, neck padding. Sturdy construction, universal size.

Arm blaster vs preacher bench: what's the difference?

Arm blaster (standing)
The elbows are locked against the plate but the body stays upright. The biceps are under tension across the full range of motion, including at the bottom where the preacher bench partly unloads. Maximum tension over the whole arc.
Preacher bench
Seated position, arms resting on the pad. Very effective at the top of the movement, but unloads slightly at the bottom. The risk of injury to the biceps tendon is also slightly higher with excessive load.

How to use the arm blaster correctly

  • Adjust the strap so the plate sits comfortably against your abdomen, with elbows slightly bent in the bottom position.
  • Choose a weight that lets you do 8–12 reps with perfect form. The arm blaster isn't designed for maximum loads — it's designed for isolation.
  • Keep your elbows pressed against the plate from start to finish. As soon as your elbows lift, the isolation is lost.
  • Control the lowering phase: 2–3 seconds eccentric. The arm blaster amplifies the benefit of a slow eccentric because the biceps stay under tension.
  • Variations: alternating dumbbells, simultaneous dumbbells, EZ bar, straight bar. The EZ bar is more comfortable for most lifters.

Frequently asked questions

Is the arm blaster suitable for beginners?
Yes, as long as you choose a light weight. The arm blaster is excellent for beginners because it teaches correct curl form by making elbow swing impossible.
Can I do anything other than curls with the arm blaster?
Mainly curls (dumbbells, barbell, EZ bar). Some lifters use it for close-grip triceps extensions, but the arm blaster is designed and optimised for biceps curls.
