The Pec Fly Rear Delt is a piece of indoor gym equipment that targets the pectoral muscles and the rear deltoids. It is designed to strengthen and tone these muscles through a specific range of motion. The equipment typically consists of a seat with a backrest, two handles or levers, and a weight stack for resistance. The user sits on the seat and adjusts the handles to a comfortable position. The weight stack can be adjusted to the desired level of resistance. To perform the exercise, the user grasps the handles and pushes them together in front of the chest, engaging the pectoral muscles. Then, the user opens the arms out to the sides, squeezing the shoulder blades together and activating the rear deltoids. This motion resembles the flapping of wings, hence the name "Pec Fly Rear Delt." The Pec Fly Rear Delt is a popular choice for individuals looking to strengthen and tone their chest and shoulder muscles. It can be used by people of various fitness levels, as the resistance can be adjusted accordingly. It is often found in commercial gyms and fitness centers, but can also be purchased for home use.
