One Machine. Two Complete Arm Workouts.
Part of Nautilus Instinct Strength, the Dual Biceps Curl/Triceps Extension delivers a quick, complete arm workout for users of every level. Fast, intuitive adjustments keep circuits moving, and the patented Lock N Load® weight selection system lets members change resistance in seconds — no pins required.
Key Features
Dual-Function Design
One station performs both biceps curls and triceps extensions, maximizing exercise variety in a single footprint.
Lock N Load® Weight Selection
Nautilus's patented Lock N Load system lets users change resistance instantly, without fumbling for a selector pin.
Multi-Position Hand Grips
Multiple grip positions let users vary hand angle for both the curl and extension movements.
Ratcheting Adjustable Seat
A ratcheting seat mechanism dials in the correct position quickly between users.
Walk-Through Entry
An open, walk-through frame design speeds up circuit transitions and welcomes users of all mobility levels.
Description
Built for facilities that want a complete strength circuit in a small footprint, the Instinct Dual Biceps Curl/Triceps Extension blends easily with the rest of the Instinct Strength line or with Nautilus cardio equipment for a cohesive facility look. A cable-driven transmission and removable wear strap keep the machine running smoothly and protect the upholstery under heavy commercial use, while rubber feet protect flooring in busy training areas.
Members can complete a full circuit independently or with instructor guidance in as little as 30 minutes.
