🚨 If your pec fly looks like you’re hugging someone… you’re not training chest… you’re wasting reps and stressing your shoulders. Seat too low. Handles too high. Elbows locked. And you’re wondering why your chest won’t grow. Here’s the science 👇 🧠 The pec’s job = horizontal adduction of the humerus. Not “bring your hands together.” So if your setup is off: ❌ GH joint (shoulder) isn’t aligned with the machine ❌ fiber direction (clavicular → sternal → intercostal) isn’t matched ❌ tension shifts to delts + biceps ❌ pec never fully shortens You’re moving weight… not loading the muscle. ⚠️ Most people never fix the setup. They just: 👉 add more weight 👉 do more reps 👉 hope it works It won’t. Here’s how to fix it 👇 ✔️ Align the joint first Set the seat so your glenohumeral joint lines up with the handles → this matches the pec fiber orientation ✔️ Free the scapula Add a small pad/roller behind your back → allows natural protraction/retraction → avoids being pinned into internal rotation ✔️ Soft bend in elbows (don’t lock out) The target is the humerus path, not elbow position ✔️ Arc, don’t shove forward Think: bring your upper arms across your body, not hands together ✔️ Peak contraction cue “Biceps touch” → ensures full shortening of the pec 🧠 Hypertrophy = tension in the right tissue If the alignment is off… The stimulus is off. If your pec fly feels more like front delts and arms… That’s your answer. 👉Like and Follow for no-BS, science-based lifting 👇 Share with a bro or broette who needs to level up their technique 😎👌🏻 Or save this and fix your next set…. you’ll feel the difference immediately. #pecfly #chestworkout #hypertrophy #biomechanics #sciencebasedfitness progressiveoverload trainingintelligence shoulderhealth injuryprevention healthpillars fitover30 fitover40 workoutsmarter notlazy
