@deltabolic: Pullover vs. Skull Crusher They may look similar, but the movement happening at your elbows and shoulders is completely different. 🔹 Barbell Pullover: Your elbows remain slightly bent while your upper arms travel backward and forward at the shoulder. The movement is primarily shoulder extension/flexion, with relatively little change at the elbow. 🔹 Lying Triceps Extension: Your upper arms remain relatively stationary while your elbows bend and straighten. The triceps are responsible for extending the elbow and driving the movement. Same barbell. Similar starting position. Completely different joint actions — and different muscles doing the work.
