Off the main topic, but perhaps relevant.... based on personal experience, exercises like biking (esp stationary) and rowing (leg part) can cause piriformis syndrome[1] if not complemented with a set of actions targeting orthogonal actions/muscle movement. During the winter I knew I would not go to the gym, so I purchased an exercise bike and used it religiously every two days. I was exercising but there was a pain in the buttocks and it was getting worse and I finally had to stop. Sitting at work caused pain after 1 hr, then 30 minutes, then 15. Driving to work caused pain. Stopping the bike did not help alleviate the problem. Went to the Dr who referred me to a physio. None of the exercises given to me helped. It took me a while to diagnose what I was experiencing - googling symptoms finally led me to a set of exercises that has helped incredibly. I am not fixed yet; I have to do the exercises ideally twice a day or at a minimum once every two days. It is much much better but it was torture when undiagnosed. So if you have pain in the "middle of each or both buttocks" when sitting for a small amount of time, consider piriformis syndrome. If you feel you are constantly clenching your buttocks read up on it as well. The exercises to get relief are very simple, can be done lying down, and start showing promise after about 2 days. The exercises I do are on Youtube. Which reminds me... I need to call my physio and let her know... hopefully this information helps someone else.
