Arm day gets machine-level precision from this 2-in-1 preacher curl and triceps extension station, where a 7-level seat and 24-position sprocket adjustment align the pad to any lifter. Isolating the biceps on curls and triceps on extensions maximizes muscle engagement while the carbon steel frame steadies 165 lbs of loading. At 54.5 lbs the seated station brings focused upper-arm sculpting into home gyms without a full cable setup.
