How to Do Bench Press

Bench Press demo video

Bench Press Muscles Worked: Chest

Form

  1. 1. Slowly lower the barbell until it touches below your chest.
  2. 2. At this time, your forearms should be perpendicular to the floor.
  3. 3. Slowly lift the barbell back to the starting position.

Coach's Tips

  1. 1. If the barbell does not touch your chest, please lower it as much as possible without overexerting yourself.
  2. 2. Be careful not to let your shoulders come forward of your chest, as this can put strain on your shoulders.
  3. 3. Please be careful not to let your hips come off the bench.
