Time to fix the imbalance in pecs

I noticed this in balance 25 years ago and really didn’t know how to attack it. In the last couple years I’ve been doing tens of thousands of push-ups every year and I thought it would just take care of itself. But it really hasn’t so I decided to start a regiment that should conquer the imbalance after just one week I am amazed to see there’s already a major difference and I’m very encouraged to continue. And I’m 52 years old!
