[Do not lower the barbell until it touches the chest when bench pressing] In order to lift more weight, powerlifters deliberately lower the barbell in a controlled manner to touch the chest and then push it up. The latissimus dorsi muscle not only plays a supporting role, but also There is also a "borrowing" effect. However, fitness exercises are different from powerlifting exercises for the purpose of lifting weights. If you use the strength of the latissimus dorsi to perform bench presses, the intensity of the exercise for the chest muscles will be reduced, so avoid lowering the barbell to touch the chest during bench presses.
