Can posture be improved with muscle?

Yes, posture can be improved with muscle. Andrew Huberman emphasizes that muscle strength and control play a crucial role in maintaining good posture. He explains that muscle is vital for posture, affecting how we breathe and our overall alertness. Enhancing muscle quality, whether by increasing muscle size or strength, changes the way our entire system functions, including the nervous and immune systems 1.

Additionally, Jeff Cavaliere notes that balancing muscle actions, such as incorporating external rotation exercises for the shoulder, is important for maintaining proper posture and preventing imbalance, which can arise from dominant internal rotation due to daily activities 2.
