Transform your home into a professional strength training facility with the Marcy Pro SM-4903 Smith Machine Cage and Adjustable Weight Bench. This complete all-in-one home gym system delivers over 50 exercise options, combining a precision Smith machine, dual cable crossover system, Olympic free-weight rack, and commercial-grade adjustable bench in one compact, space-saving design.
Complete Multi-Functional Home Gym System
The SM-4903 targets your entire body with unmatched versatility. This premium multi-gym Smith cage system features a sealed ball bearing pulley system for smooth, controlled movements during upper and lower cable exercises. The universal design allows you to add different gym attachments as you progress, giving you complete control of your workouts and keeping training sessions ever-changing and challenging.
Dual Cable Crossover System for Maximum Versatility
What makes the Marcy Pro Smith Machine SM-4903 unique is its dual rotating upper and lower pulley system that runs on two independent pulley trolleys. Set different weights on each side for unilateral training or use the unit as a circuit trainer for 1-2 users simultaneously. The 2000 lbs tensile strength aircraft cable and 3¾" nylon pulleys with sealed ball bearings deliver commercial gym performance at home.
Includes 2 cable handles for crossovers, allowing you to efficiently target chest muscles, biceps, triceps, and more with precision cable movements.
Guided Smith Press with Ultra-Smooth Linear Bearings
-
Precision Smith Bar: Ultra-glide bushings ensure smooth, controlled motion with knurled grip for maximum control
-
Adjustable Safety Stoppers: Multiple height settings prevent the Smith press from going past safe ranges
-
Linear Bearing System: Professional-grade guided movement for perfect form on every rep
-
Adjustable Bar Catches: Set to any height for safe racking at multiple positions
Independent Free Weight Power Cage Functionality
Beyond the guided Smith bar, the SM-4903 allows you to use an independent 7ft Olympic barbell like a traditional power cage. The 2 adjustable external bar catches and 2 full-length safety catch structures on each side can be set to any height as a secondary safety precaution to rack the bar safely during squats, bench press, and deadlifts inside the unit.
Commercial-Grade Adjustable FID Weight Bench
The standout feature is the fully adjustable weight bench with commercial quick-release adjustment system. Move the bench easily thanks to the carry handle and transport wheels, letting you tackle free weight exercises with dumbbells and target more muscle groups.
