The Bench Press



        One of the most popular exercises in the gym these days is the bench press and it’s variations. If anything, it’s a favourite of those who work out the t-shirt muscles exclusively. Moreover, most newbies will spend a workout day doing bench presses (and other variations) to the exclusion of other exercises.

            It’s one of the three main lifts in Powerlifting, along with the squat and the deadlift. The bench press is used as one of the measures of upper body strength and goes along with the bragging rights in the gym. When people find out a person works out, or goes to a gym, or has a wide chest, the first question asked is how much do they bench press.

This exercise can be performed with a barbell or dumbbell.  The supine position of the exercise can be in a flat, 180 degree position, or it can be in a decline (the head is lower than the legs) position, or an incline position. If a barbell is used, grip width can also vary from narrow, to medium, to wide variations. The barbell flat bench press with a medium grip will be discussed here.

Primary muscles involved (2, 3)


            - Pectoralis Major

            - Coracobrachialis

            - Anterior Deltoid



Secondary muscles: (2, 3)


            - Triceps Brachii

Execution and Performance: (1, 2, 3, 4)

1. Lie supine on a flat bench, keeping a five point contact position with the bench and the floor:

  • Back of the head in contact with the bench
  • Upper back evenly contacting the bench 
  •  Buttocks evenly placed on the bench 
  • Left and right foot flat on the floor
2. Position under the bar, with the eyes at the level with the bar. Back should be slightly arched.

3. Take an overhand grip on the bar, hands slightly wider than shoulder width apart.

4. Lift the barbell off the rack, or have a spotter assist you in off-racking the barbell, into the starting position.

5. Position the bar above the chest, level of the nipple line.

6. Inhale as you lower the  bar to the chest. 

7. As soon as the bar touches the chest, pause and push the bar back up. Do not bounce the bar off the chest. 
    Hold your breath until past the sticking point, then exhale as you continue past. 

8. Lock-out the elbow at the top position. 

9. Repeat for the desired number of repetitions.

       In a recent video from Joel Jamieson of www.8weeksout.com, if one were to use the bench press for sports performance, the set-up for the exercise would be a little different. The arch mentioned above will be more moderate as compared to that of, say, a powerlifter. Powerlifters generally have a high arch so that they have better leverage and decreased range of motion. This allows them to lift the heaviest weight possible through a shorter range of motion. (5)



            The other set-up point that was also addressed in Jamieson’s video is using the feet and hips. He advocates the use of the feet and hips driving into the ground and transfer the force through the body into the bar. The core must be tight.  (5) This is different from the standard bench press where the feet are used to balance the body on the bench for safety purposes.


            The last point emphasized is the postion of the arms. In bodybuilding, the bench press is done with arms abducted and the bar relatively high. Coach Jamieson suggests that the position of the arms be closer to 45 degrees from the body. This mimics the most athletic pressing movements where the arms are closer to the body. (5)

           The full video of coach Jamieson on the bench press for athletic performance is here.


Sports Uses: (3)

        The movement of the joints in the exercise are horizontal adduction/flexion, elbow extension, and scapular protraction. The bench press can aid in sports that require reaching, pushing, side arm throwing, and punching. Some of the sports that can benefit from this exercise are the martial arts, football (blocking), racket sports (forehand stroke), throwing events in athletics, the floor exercise in gymnastics.
