Many people are currently working from home in sub-optimal ergonomic situations. I hear about it daily in my practice.  Not everyone is comfortable being back at the gym and the motivation to exercise and mobilize may be lacking in some. Backs and necks are protesting, butts are getting weaker from sitting so much, and things could be better. SO much better.
This is an excellent 12 minute video demonstrating a few different dynamic standing postures that will strengthen and mobilize the whole postural system. No equipment is needed. You should find some relief immediately in that tight low back, short hamstrings and burning neck. Warning: you need to work for it, but those 12 minutes are golden. Do these daily for a week and you’ll be surprised at the results.
To your health,
