The Nautilus Leverage Tricep Dip is a compound upper body movement that primarily targets all three heads of the triceps brachii while engaging the chest, shoulders, and upper back as critical stabilizers, building the functional upper body strength that transfers directly to pressing, pushing, and performance movements across every training program. Unilateral arms address asymmetries most machines miss, while the two-bar linkage delivers the renowned Nautilus Cam load curve, ensuring maximum muscle recruitment through the entire range of motion.
