The rear delt/pec fly machine, also known as the reverse fly or chest fly machine, is a versatile piece of gym equipment designed to target the muscles of the upper body, particularly the shoulders and chest. It can be adjusted to perform two different exercises: rear delt fly for the posterior deltoids and upper back muscles, and pec fly for the pectoral muscles. Here’s an introduction to the rear delt/pec fly machine:
Design and Features
- Structure: The machine typically consists of a seat and backrest, along with adjustable arms or handles connected to a weight stack or cable system.
- Adjustable Arms: The arms can be adjusted to change the exercise from a rear delt fly to a pec fly, allowing for multiple muscle groups to be targeted with one machine.
- Weight Stack: Resistance is provided by a weight stack that can be adjusted using a pin, allowing you to easily change the weight load.
Benefits
- Muscle Isolation: The machine allows for the isolation of specific muscle groups, making it effective for targeting the rear deltoids and pectoral muscles.
- Versatility: By adjusting the machine, you can perform two different exercises, providing a comprehensive workout for the upper body.
- Stability and Support: The machine provides support for your back and arms, allowing you to focus on the target muscles with reduced risk of injury.
