For bad postures, this video is good.

A little aggressive video for people with neck issues , but people with good spinal alignment, postures and little to no issues can follow this. Few of the exercises were demonstrated well like rows (shoulder retraction/adduction) , stretching part is good, pectoral stretch should be progressed slowly ( like placing one arm 90-90 position on the wall , with one step in front of the other & create a rotation away from the wall to stretch pectorals unilaterally, then bilaterally ).

Is a very good video, She stabilizes her pelvis that gives an isolation to neck muscles for a more effective stretch with a better spinal alignment. I would recommend this video.

Could be a little tricky for people especially with faulty neck postures. Those with neck stiffness & slight achy neck can try it, but be cautious not to do it for longer.
