When lifting a heavy object, which muscles should be avoided?

When lifting a heavy object, it is important to avoid relying on the back muscles because they are more susceptible to strain and injury compared to other muscle groups. The back muscles, particularly the lower back, are not designed to bear heavy loads when lifting in a standing position. Using the back inappropriately—such as bending at the waist instead of using proper lifting techniques—can lead to injuries like strains, sprains, or herniated discs.

In contrast, the legs are the primary muscle group intended for lifting heavy items, providing strength and stability. The arms also play an important role in gripping and maneuvering the object, while the core muscles stabilize the body during the lift. Engaging the legs and core while avoiding strain on the back is crucial for a safe lifting technique, which emphasizes the importance of proper body mechanics.
