Inadequate Nutrition: Proper nutrition is crucial for muscle growth. Without sufficient protein and calorie intake, the body lacks the necessary building blocks for muscle repair and growth.

Lack of Progressive Overload: Muscles need to be consistently challenged with increasing resistance to grow. Sticking to the same weights and routines can hinder progress.

Insufficient Recovery: Muscle growth occurs during rest periods. Overtraining and not allowing enough recovery time can impede muscle development.

Poor Exercise Selection: Choosing the wrong exercises can limit muscle engagement. Compound movements that target multiple muscle groups are more effective for muscle growth.
