Strength Training and Anatomy

~~ Strength Training & Anatomy ~~ We can use our knowledge of #anatomy to maximize both the efficiency and safety of strength training 💪🏋 . Lateral dumbbell raises are a great exercise for building shoulder strength. But start at 20° from vertical! . The main muscle in our shoulder is a powerful muscle called the deltoid. Between 0 - 20° of shoulder abduction however, the primary muscle involved is the supraspinatus. The supraspinatus is a small fragile muscle and member of the rotator cuff muscles, easily injured under too much stress. The powerful deltoid takes over at 20° for the rest of shoulder abduction. . Starting at 0° can put undue stress on the fragile supraspinatus, increasing the risk of shoulder impingement and rotator cuff tear 😬. Starting at 20° allows us to target the deltoids specifically 💪
