The bench press is a common fitness goal for many gym-goers, but determining an ideal weight is influenced by multiple factors. Online calculations consider factors like experience, body mass, or age. However, other factors like genetics, muscle mass, and training frequency also play a part. Some general guidelines suggest that a beginner should aim for 1 x bodyweight, intermediates 1-1.5 x bodyweight, and advanced lifters 1.5-2 x bodyweight.
  

Key Points: 

1. Bench press weight goals can be categorized based on experience: beginners (1 x bodyweight), intermediates (1-1.5 x bodyweight), and advanced (1.5-2 x bodyweight).

4. Factors like age, body mass, injury history, and genetics can affect individual bench press strength standards.
