Ez-Bar Biceps Curl (with Arm Blaster) form demonstration - targeted for Biceps Upper Arms workouts

Ez-Bar Biceps Curl (with Arm Blaster)

The arm blaster locks the elbows against a fixed brace, physically preventing them from drifting forward — the most common way lifters unintentionally cheat a curl by turning it into a shoulder-assisted movement. It forces strict form by removing the option to cheat, which usually means using less weight than a free-standing curl.
