Watched an Arnold video on chest training where he uses a wide grip for pecs. Decided to at least try it to see if it aggravated a decades old shoulder issue.
Flat bench, thumb, index outside the outer rings. Slow reps down closer to upper pecs, near touching for good stretch. Mainly paying attention to shoulder; the bad one complained a bit, but tolerable. Did slow high rep sets from twenty down to eights.

Few hours later at home, shoulder fine, better though, can really feel the upper outer pec muscles were worked. Not sore just very awake outer thick pecs.

This will be a keeper, maybe as a finisher along with decline push-ups.
