As a well seasoned driver I’m realizing the importance of good posture and leg positioning while driving. Especially on the long drives. For those of you who are athletes as well, even more important. Crazy stuff happens with hamstrings, glutes, lower back and abdomen. It’s all a connected system and very important you aren’t furthering injuries or causing them from driving. Tip: Ideally, your thigh should be slightly downward-enough to roll a pencil down it. This alleviates hip flexor pinching. Also, engage lower abs to tilt pelvis in order to sit on sitbones. Takes a bit of coordination but worth it.
