Kick your legs up. Literally.
If you’ve taken a few yoga classes, you may have experienced the pose in which you lie flat on the floor, scoot your butt against the nearest wall, and then flip your legs up against the wall. This puts you in a position your body is rarely in, which does wonders for your circulation. You don’t have to do this pose, though – you can also just put your legs up on an ottoman while you work or relax.
