Wall Angel: to improve thoracic spine mobility

Working off of yesterdays post regarding thoracic spine (T/S) stability, here is a drill that may be beneficial to perform prior to the goblet squat in order to gain thoracic spine extension.
Excessive thoracic spine flexion (AKA excessive kyphosis) may contribute to issues both up the kinetic chain to the shoulders/neck or down the kinetic chain to your lower back. With a hunched over position that most of us remain in throughout the day, our joint/soft tissue often adapt to this flexed posture; limiting us from getting that 25 degrees of thoracic spine extension that is considered the norm. When someone lacks Thoracic spine extension, often times they will compensate with lumbar spine (lower back) extension. With repeated poor movement pattern of compensated lumbar spine extension, an individual may develop extension sensitive low back pain.
Here is shown a great way to focus on LOCKING out the lumbar spine while focusing on improving thoracic extension.
-In a sitting position, march your feet as close as you can towards your butt. This will allow you take up all the joint motion from your hip and lumbar spine.
-Perform a wall angel by placing your elbows and your wrists on the wall and slowly elevation your arms until you are fully overhead; descend and repeat for 10-15 repetitions.
-If you can not get into the starting position, just reach as far back as your mobility allows and attempt a wall angel.

This is the first time I have been able to do thorasic extension test correctly. Thank you.

The fact that this is ridiculously hard for me, means I have a lot of work to do and poor posture. I'm going to work at this every day, possibly once every hour even.

My mobility is so bad that when I get into the starting position for this as you demo'd I can't even get the back of my wrists flat against the wall (they go into extension as my elbows and fingers struggle to contact the wall).
I've tried this lying down with feet flat on the floor and knees up... two questions..
1. Will I see benefits from doing it lying down as long as I keep lower back on the ground?
2. Do I need to think about pulling my traps down when I reach overhead in this exercise? It feels like they are overactive and get in the way of proper scapular rotation...

Hi,
Is wall angel/floor angel good for adressing bursitis/impingement ?
