Hello friends.
Perform this simple test.
Stand with your back against a wall.
Step your feet out about a foot from the wall, bend your knees slightly.
Tilt your hips posteriorly so that your lower back is flat against the wall.
Lift up your arms and put them flat against the wall, making a right angle at your elbows and shoulders. At this point your whole back, head, shoulders, elbows, and wrists should be touching the wall.
Now slide your arms up the wall above your head as far as you can.
If you can't do this without one of the above mentioned things coming off the wall, then you have sub-optimal posture.
