The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
This is a common cause of low back pain.
Many people may not be aware they have this going on.
Are you looking at movement patterns where your back may be over extended?
Squat mechanics? Where are you looking when you squat?
Correcting movement patterns can improve this situation. It is low grade now, however, without attention it can progress. You don’t have pain yet, however, pain is a lagging indicator.
Are you engaging your midline when squatting?
When the back is over extended the deep anterior stabilizers of the spine are weakened.
Strength in this area will help you gain control in the anterior spine.
I’d take a look at Back to the Barbell to be proactive with this situation.
