Pectoral Fly/Rear Deltoid DRE8003
Pectoral Fly/Rear Deltoid DRE8003
The Dynasty Fitness DRE8003 Pectoral Fly/Rear Deltoid is a selectorized dual-function machine that trains the pectorals through a seated fly and the posterior deltoids through a reverse fly from a single station, with a dual-handle design engineered so each exercise uses a handle geometry precisely matched to the muscle's natural movement path — horizontal handles with slight internal rotation for the pectoral fly that matches the inward adduction arc of the chest, and vertical handles with subtle external rotation for the reverse fly that aligns with the horizontal abduction path of the posterior deltoid. A 5-position arm adjustment system sets the starting position for each exercise, a 6-position backrest combined with a pneumatic seat accommodates every body proportion, and all adjustments on the machine can be completed with a single hand so setup between exercises and between users stays fast. The Dynasty Flex-Stack System delivers a true 1:1 felt weight ratio through both the fly and reverse fly directions, with a 5kg base weight and 2.5kg micro-adjustment plates for precise progressive loading. Built to commercial grade at 59"×52"×80" with a 210 lb standard stack and a 250 lb upgrade option available through Dynasty Fitness, the DRE8003 is built for commercial gyms, personal training studios, and serious home gym setups where selectorized chest and rear deltoid training from biomechanically specific handles is a programming priority.
- Selectorized dual-function pec fly and rear deltoid machine with purpose-engineered handle geometry for each exercise — horizontal handles with slight internal rotation for chest targeting and vertical handles with subtle external rotation for rear delt activation, so both muscles work through their correct biomechanical path rather than sharing a compromise handle position
- 5-position arm adjustment sets the starting arc for both exercises so the resistance engages at the correct point in the movement for each user's shoulder width and mobility, preventing the overstretched starting position that causes shoulder discomfort on fixed-arm machines
- Every adjustment on the machine — arm position, backrest, and seat — operates with a single hand, which means transitioning between pectoral fly and reverse fly within a superset or between users in a commercial session adds no meaningful time to the session
- Dynasty Flex-Stack System delivers a true 1:1 felt weight ratio through both fly directions, with 2.5kg micro-increment plates starting at a 5kg base for the precise progressive loading that chest and rear deltoid hypertrophy training demands

Exercises and muscles targeted
Exercises and muscles targeted
| Exercise | Muscles Targeted |
|---|---|
| Pectoral Fly (horizontal handles) | Pectoralis Major — Sternal Head (primary — horizontal adduction at mid-chest), Pectoralis Major — Clavicular Head (secondary), Anterior Deltoid (secondary), Coracobrachialis (secondary) |
| Reverse Fly (vertical handles) | Posterior Deltoid (primary — horizontal abduction), Rhomboids (scapular retraction, primary), Middle Trapezius (secondary), Infraspinatus (secondary), Teres Minor (secondary) |
| Pectoral Fly — Upper Chest (backrest adjusted higher) | Pectoralis Major — Clavicular Head (increased upper chest emphasis with higher backrest, primary), Pectoralis Major — Sternal Head (secondary), Anterior Deltoid (secondary) |
| Reverse Fly — Isometric Hold (peak abduction) | Posterior Deltoid (sustained isometric at peak horizontal abduction), Rhomboids (sustained scapular retraction), Middle Trapezius, Infraspinatus (co-contraction throughout hold) |
| Pec Fly/Reverse Fly Superset | Pectoralis Major (fly phase — chest adduction), Posterior Deltoid, Rhomboids (reverse fly phase — horizontal abduction and scapular retraction) — anterior and posterior shoulder balance trained consecutively from one station |
| Eccentric Fly or Reverse Fly (slow controlled return) | Pectoralis Major (eccentric stretch loading at full arm extension — fly) or Posterior Deltoid, Rhomboids (eccentric at full adduction — reverse fly) — Dynasty Flex-Stack 1:1 ratio delivers consistent resistance through the full eccentric return |
The DRE8003 addresses one of the most common imbalances in upper body programming — overdeveloped anterior deltoids and chest relative to the posterior deltoid and scapular retractors. Most pressing-dominant programmes accumulate significant chest and front delt volume while the rear deltoid and rhomboids receive far less dedicated work. Pairing pectoral fly and reverse fly from a single selectorized station allows anterior and posterior shoulder balance to be addressed in the same session without equipment changes, and the handle geometry on the DRE8003 is purpose-built for each exercise rather than using a compromise handle that trains neither optimally.
