What muscles should not be used when lifting?

When lifting, it's important to avoid using muscles that can lead to injury or improper form. Specifically, you should minimize the use of your back muscles, particularly the lower back, to prevent strain; instead, engage your legs and core for support. Additionally, avoid relying on your shoulders and arms excessively when lifting heavy objects, as this can lead to shoulder injuries. Focus on proper technique and body mechanics to ensure safety and effectiveness.
