Every single time you reach into the back seat, carry heavy groceries, or type at a desk for 8 hours, your SITS muscles are putting in overtime. 🦺
Your rotator cuff doesn’t just work when you’re lifting heavy in the gym. Every daily movement forces these 4 small muscles to fight gravity:
🔹 Typing & Slouching: Forces Subscapularis into overdrive, keeping the joint locked forward.
🔹 Reaching High Overhead: Squeezes the Supraspinatus through a tight bony passage.
🔹 Carrying Bags & Steering: Demands non-stop micro-adjustments from Infraspinatus and Teres Minor to hold the socket centered.
When these 4 get fatigued from poor posture and daily wear, simple movements turn into shoulder impingement and sharp pain.
Protect the core 4: Supraspinatus, Infraspinatus, Teres Minor, Subscapularis.
