⚡ At a Glance
- • Wearing Comfort: Padded foam neck and highly dense elbow pads with adjustable nylon strap for a secure, comfortable fit
- • Best for: Bodybuilders, weightlifters and CrossFit athletes aiming to isolate biceps during curls
- • Not ideal for: Exercises that require full shoulder mobility or multi-joint compound lifts rather than isolated curls
Universal bicep isolator designed to improve curl positioning. Adjustable fit, quick-release strap and dense padding support focused biceps work.
Cleaner Curl Form – with an adjustable arm plate and elbow pads
Arm blaster design locks the elbows in place while the adjustable nylon strap secures the plate at the chest height, preventing forward lean. Highly dense elbow pads cradle the arms so alignment stays consistent during repetitions.
Improved form keeps tension on the biceps rather than recruiting shoulders, making each rep more effective for hypertrophy and strength.
Comfort for longer sessions – thanks to padded neck support
Comfortable foam neck padding distributes load across the upper chest and shoulders rather than concentrating pressure on the neck. Padding reduces friction and pressure points when using heavier loads.
Longer sets and heavier working sets become more tolerable, allowing more productive training without early discomfort.
Supports progressive overload – with heavy-duty construction and quick-release strap
Heavy-duty build and an adjustable nylon strap with quick-release allow fast repositioning between sets while handling increased loads during dumbbell or barbell curls. Secure fastening maintains consistent plate height under strain.
Safer transitions and reliable positioning help lifters steadily increase weight and volume, a key factor in muscle growth.
