One of the most common swing flaws in the golf swing is tension and an of overactive mind. Golf is mentally challenging and requires a connection of body and mind. Our breathing is our internal physical mental state. Any time we experience stress on the golf course such as first tee jitters, hitting over water, we trigger a fight flight response from our sympathetic nervous system resulting in a loss of blood flow to the brain. Most golfers are not aware of their breathing patterns. Incorporating diaphragamatic breathing into your Pre-Shot Routine will calm the mind, relieve tension, and increase your sense of rythem and tempo.. Our breath is our best friend. The deeper the breathing the easier the swing.
