Gym accessory aimed at strict curl form and focused arm isolation, promoting cleaner reps and better muscle engagement. For lifters frustrated by shoulder swing and stalled bicep growth, using RDX Arm Blaster concentrates effort where it matters. Is this the right training aid to upgrade regular weightlifting sessions?
⚡ At a Glance
- • Isolation Performance: Contoured plate locks the back and elbows to isolate biceps and triceps during curls
- • Best for: Weightlifters and bodybuilders wanting strict form and targeted arm development
- • Not ideal for: Users who prefer free shoulder movement or compound, full-body lifting sessions
Powder-coated aluminium frame and contoured plate keep elbows fixed for strict curling. Padded neck support and embossed EVA reduce momentum while cushioning the neck during heavy sets.
Bigger biceps and triceps – With powder-coated aluminium and contoured plate
A rigid, 23-inch aluminium plate sits against the torso and places elbows into a fixed channel, preventing shoulder drift. The curved, centrally balanced shape ensures consistent alignment through each rep.
More direct biceps and triceps loading helps stimulate hypertrophy by removing compensatory movement. Expect cleaner repetitions that target the intended muscles rather than shoulders.
Reduced momentum for cleaner reps – Thanks to embossed EVA padding
6mm-thick embossed EVA padding on the curl support mimics a curled barbell pad and absorbs shock, increasing friction against the arms. That dampens unwanted speed and reduces cheating during heavy or fast reps.
Slower, controlled repetitions become the default, improving time under tension and technique. Fewer momentum-driven reps lead to more effective sets and steadier progress.
Custom fit and comfort – With adjustable 42-inch strap and 6mm neoprene neck pad
A 42-inch strap adjusts via a touch fastener and durable buckle, while a quick-release mechanism simplifies fitting. The 6mm neoprene neck pad cushions pressure from the support plate during extended sets.
Comfortable sessions reduce neck strain and let users focus on form, even during heavier workloads. The long strap accommodates a wide range of torso sizes and gym setups.

🏆 Our Verdict
Best suited for lifters focused on improving curl technique and isolating arm muscles rather than performing compound shoulder-driven moves. The combination of a rigid aluminium plate, embossed padding, and a long adjustable strap makes strict, repeatable curls easier to achieve. While some may prefer simpler straps, the durable construction and ergonomic padding make it a sound long-term training aid.
