Dual Pectoral Fly and Rear Delt Machine | BodyKore (GR633)

Train Chest and Rear Deltoids on One Selectorized Machine

The BodyKore GR633 combines pectoral fly and rear delt exercises into one selectorized strength machine, allowing users to perform both chest and posterior shoulder isolation movements without changing equipment. The dual-function design helps maximize training efficiency while reducing the amount of floor space required for dedicated upper-body machines.

The GR633 is well suited for commercial fitness centers, schools, universities, apartment fitness rooms, hotels, corporate wellness facilities, personal training studios, and home gyms seeking commercial-quality selectorized strength equipment.

Selectorized Resistance System

The standard GR633 includes a 220 lb. selectorized weight stack that allows resistance adjustments using a selector pin instead of manually loading weight plates. This allows users to change resistance quickly while helping maintain an organized training environment.

Because selectorized machines use pulleys and leverage systems, the resistance experienced during exercise may differ from the labeled stack weight. Users should always select resistance appropriate for their individual strength level and training goals.

Optional 340 lb. Weight Stack Upgrade

Facilities serving stronger or more experienced users can equip the GR633 with an optional 340 lb. selectorized weight stack. The upgrade is sold separately and increases available resistance without changing the machine's footprint.

Unless specifically selected during purchase, the optional weight-stack upgrade is not included with the standard machine.

Pectoral Fly Exercise

The pectoral fly function isolates the chest muscles through a controlled converging movement designed to provide smooth resistance throughout the exercise. Adjustable movement arms help accommodate users with varying shoulder widths and preferred starting positions.

Rear Delt Exercise

The rear delt function targets the posterior shoulder muscles using the same selectorized resistance system. Switching between pectoral fly and rear delt exercises allows users to train opposing upper-body muscle groups without moving to another machine.

Commercial Construction

The GR633 is built using heavy-duty steel construction, commercial-grade upholstery, and precision selectorized components designed for repeated daily use. The selectorized design allows quick resistance adjustments, making the machine practical for busy commercial facilities with multiple users.

Dimensions and Facility Planning

The assembled machine measures approximately 57 inches long, 56 inches wide and 77 inches high. Its compact footprint allows facilities to provide both chest and rear shoulder isolation exercises without requiring separate selectorized machines.

Before ordering, verify ceiling height and measure all exterior doors, interior doors, hallways, elevators, stairways, and the final installation location.

Floor Planning

The GR633 weighs approximately 502 pounds. Install the machine on a stable indoor surface suitable for commercial strength equipment.

Commercial rubber gym flooring can help protect finished floors and improve equipment placement, but flooring does not determine structural load capacity. Facilities with upper-level installations should verify structural suitability before delivery.

Assembly and Installation

Assembly is required. Install the frame, guide rods, weight stack, pulleys, cables, movement arms, and seat components according to the current BodyKore instructions before placing the machine into service.

After assembly, verify that all hardware is secure, the selector pin engages correctly, and the weight stack moves smoothly throughout the complete exercise range.

Shipping and Receiving

The GR633 ships by commercial freight. Before shipment, verify unloading requirements, liftgate service, delivery access, and final equipment placement.

Standard freight service should not be assumed to include inside delivery, room placement, unpacking, debris removal, or assembly unless those services are specifically arranged.

Warranty Overview

The warranty includes lifetime coverage on the frame excluding coatings, ten years on weight stacks, pulleys and pivot bearings, three years on components not otherwise specified, one year on upholstery, cables, springs and grips, and six months on accessories.
