Frequently asked questions

What muscles does the bench press work?

The bench press primarily works the chest (pectoralis major), the front deltoids and the triceps. The incline variation shifts more load onto the upper chest and front delts.

Why don't I feel bench press in my chest?

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.

Incline vs flat bench — what's the difference?

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.
