Don’t lean too far forward; it should be a stretch, not painful.

Open Your Chest

The pectoral muscles, or "pecs," tighten up when the shoulders are carried forward all the time, and as a result of doing too many bench presses and pushups. In a corner, put your forearms against the wall. Lean forward, pushing your chest toward the wall. Feel the stretch across the front of your chest and shoulders. Hold this position for 30 seconds and repeat three times. If you do not have an empty corner, the stretch can be performed one arm at a time in a doorway. Don't lean too far forward; it should be a stretch, not painful .
