Usually the serratus anterior muscle does not need special training. In chest muscle training, you can get the perfect serratus anterior muscle with a small skill of "deformation".

Pull up your supine arm.

Lying arm pull-ups is a necessary training, because it not only strengthens your serratus anterior muscle, but also exercises your latissimus dorsi, pectoralis major and triceps, which benefits you a lot.

push-up

Push-ups are also a training method of the serratus anterior muscle, which can stimulate the serratus anterior muscle of the trainer more effectively than supine arm pull-ups, but you need to do more when doing this training. To be exact, when your arms are straight and your body reaches the highest point, you should spread your shoulders forward and then pause for a moment. This principle also applies to other similar chest muscle training.
