The bench press is the go-to upper-body pressing lift, building the chest, front delts and triceps together.

Often the triceps and front delts take over. Setting your shoulder blades back and down, and thinking about pushing your chest toward the bar, helps target the pecs.
Flat bench spreads the load across the whole chest; incline bench (15–30°) biases the upper chest and front delts. Most balanced chests are built using both.
