I do now... After working an IT job for 20+ years (sitting) and even worse, for last decade from home, I sit all day.
My hams, lower-back and hips are now garbage when it comes to flexibility.
2 days a week now I go in, I use the "turf room" and do a 20-minute conditioning session. (Intervals, etc).
Airdyne, farmers walk, sled drags, etc. After that, I stretch out very good. MY favorite thing is to hold light d-bells, and lean FWD while sitting on a utility-bench.
Lower-back and hams have gotten so much better in a month, its night/day. I throw in some hip stretches. I limp around in much less pain after SQ and DL days now.
