Watch Dr. Greg Sher demonstrate wall angels: A brilliant (and very difficult) postural exercise. 

What does this exercise achieve?

The wall angels exercise targets and engages all of our core muscles and shoulder stabilisers. It is an excellent aid to improve our middle back extension and shoulder mobility. In fact, if completed in conjunction with “floor angels” and a foam roller extension, this is one of the best exercises to counteract poor posture from device (laptop, computer and phone) use.

The big tip:

Start slow, and do a little every day to slowly improve posture, stability and strength.
