For those that have desk jobs, are there any alternatives to sitting in a chair that I can do to assist strength and joint mobility? (I've tried a stand-up desk and it hurts my ankle after a while.)
- Would sitting on a stability ball help with posterior pelvic tilt? (It's difficult trying to straighten my lower back while sitting up straight in the pike, Fundamental Day 4)
- Are there any GST exercises or stretches you do while in your office or cubicle, sort of a mini-workout or stretch?
