bench press
The bench press is an upper body strength training exercise that consists of pressing a weight upwards from a supine position. The exercise works the pectoralis major as well as supporting chest, arm, and shoulder muscles such as the anterior deltoids, serratus anterior, coracobrachialis, scapulae fixers, trapezii, and the triceps. A barbell is generally used to hold the weight, but a pair of dumbbells can also be used.
The barbell bench press is one of three lifts in the sport of powerlifting and is used extensively in weight training, bodybuilding, and other types of lifting fitness training to develop the chest muscles.
== Movement ==
The person performing the exercise lies on their back with a weight grasped in both hands. They push the weight upwards until their arms are extended, not allowing the elbows to lock. They then lower the weight to chest level. This is one repetition (rep).
Powerlifting: take posture with body weight resting on buttocks and upper traps whilst driving feet into the floor. Movement requires the weight to be taken at full arms' length, lowered to upper torso, paused, and then lifted to starting position.
