To hit the upper clavicular fibers of the pecs (“upper chest”) you ideally want to motions. The first is angular flexion of the shoulder from low and away to up and in. The second (building on the “in” portion), you want adduction of the arm across midline. This Olympic Bar landmine variation checks both boxes at once. ✅✅ Give it a shot and light up those fibers like never before. Let the gains begin! P.S.

Feet up bench press! This exercise doesn’t allow you to isolate your pecs better. In fact, it’s worse for building muscle because it decreases your stability and therefore decreases the amount of weight you can lift, making it less stimulating for muscle building. However, there is still a purpose for this exercise, and that is to relieve discomfort on the lower back if the lifter has an aggravated back from arching backwards (spinal extension). Now I’m not saying arching is bad. Arching is good

The Pec Major: Part 1 - Anatomy of a Beautiful Muscle 💪✨ The Anatomy 🔬 The pec major has 3 heads: 1️⃣ Clavicular head (upper pec) – Attaches to medial half of clavicle 2️⃣ Sternocostal head (mid pec) – Attaches to sternum ribs 2-6 3️⃣ Abdominal head (lower pec) – Attaches to rectus sheath (can vary or be absent!) All three converge to insert on the humerus (arm bone)! The Functions 💪 All 3 heads work together for: ✅ Internal rotation of shoulder ✅ Adduction ✅ Horizontal adduction (the most lo
