הנה מה שהוא כותב:

Tuck your shoulder blades underneath your body and pinch them together and down. This will elevate the ribcage and stabilize the shoulder girdle. Maintain this state of tightness in your upper back/traps during all repetitions. This will also create a natural arch in the lower back, and will create a stable platform out of your upper back muscles for you to press from. This is called "shoulder joint retraction" and will make your rotator cuff very happy when benching.

האם חשוב להקפיד על זה? פעם ראשונה ששמעתי על הדבר הזה.
