Four back-to-back calls on Tuesdays used to leave my hips locked up by 4pm, and I’d just sit through it since standing up felt like it would eat into the next meeting. What actually fixed it was blocking a hard 5-minute gap after every call instead of letting them run together, set to trigger at 50 minutes, not 60, so there’s no excuse to skip it.
In those 5 minutes I do a couch stretch against the chair, one side then the other, then a standing hip flexor lean by the window. No equipment.
It’s been about 6 weeks now and the late afternoon stiffness is mostly gone, though it comes right back if I skip two gaps in a row.
