Uncomfortable hotel beds, I find if you put a pillow up under the top of your legs near your butt there is significant relief. Long drives, making a point of using the cruise control and having your legs evenly stretched out as often/long as possible I’ve found makes a huge difference. I’ve done many 600+mile driving days and that is what works for me.
I’m also making a point of doing more mobility work as part of my gym routine. I’ve upped my 2 day workout to 4 with the other 2 days having a heavy leaning towards mobility work. I’ve found many neglected smaller muscles as a result and I am much freer moving now. I also found this morning stretch that has worked wonders for me
