Rear delt fly targets upper back and shoulder muscles, especially rear deltoids. Exercise improves shoulder stability and prevents injuries. Proper form includes neutral grip, straight back, and controlled movements
Exercise targets rear deltoids and upper posterior muscles. Deltoid posterior pulls arms behind body and pulls scapula back. Deltoid lateral forms roundness and raises arms laterally. Rotator cuff muscles infraspinatus and teres minor assist shoulder stability. Trapezius muscles lower and middle fibers work shoulder blades
Biceps flex elbow and brachialis are heavily stimulated during hammer grip. Forearms control grip strength and are crucial for wrist hooking. Rotator cuff muscles, especially subscapularis, are primary for shoulder rotation
15° angle targets upper chest, ideal for beginners. 30° angle provides balanced chest development. 45° angle emphasizes front delts, second best for upper chest. 60° angle focuses more on front delts, almost overhead press
Pectoralis major originates from clavicle, sternum, ribs and external oblique fascia. Muscle has two heads: upper clavicular and lower sternocostal. Sternal head accounts for over 80% of total muscle volume. Two heads converge laterally and insert into humerus' greater tubercle
Shoulder muscles consist of anterior, lateral, and posterior deltoids. Shoulder press is most effective for anterior deltoids. Lateral raises target lateral deltoids, while rear deltoids need extra focus
