The Precor EFX 546i V4i Big Body is a remarkable piece of workout equipment—a machine built with the fitness enthusiast in mind. Its strong, all-steel construction ensures years upon years of long-lasting durability, and its many unique features demonstrate why the Precor Corporation is one of the undisputed leaders of the fitness industry. The EFX Big Body comes standard with 10 pre-programmed workout options, as well as a Quick Start button that allows users to program the machine as they begin the warm-up phase of their workout. Each of the 10 preset workout programs, ranging from hill training to fat burning to fitness tests, has over 20 levels of resistance. This variety in the level of difficulty makes the Big Body the perfect piece of workout equipment for beginner, novice and expert athletes alike.

The Precor EFX 546i V4i Big Body is completely self-powered. It boasts a stride plain that ranges from 21.2 inches when the patented CrossRamp is at 13 degrees to 24.7 inches at 40 degrees. The perfect machine for the serious cross trainer, the Big Body allows for 240 minutes of continuous workout time—much longer than many other machines in this equipment category. Moreover, this ergonomically designed machine essentially offers four broad types of workouts—walking, running, cycling and stair climbing—depending on how one chooses to use it.

The large, Tap-Control display panel on the Precor EFX 546i V4i Big Body helps exercisers track benchmarks such as time elapsed, calories burned per hour and total distance traveled. The heart rate sensors, located within the handles of the machine, continuously monitor the user’s heart rate, and display the results in graphic color on the Precor SmartRate Biofeedback console. The two polyurethane wheels located to the rear of the Precor EFX 546i V4i Big Body allow for easy mobility, making it possible to move the machine effortlessly from room to room.
