If you’ve been putting in the work and it has made your wallet fat, good for you. Just remember that you may want to carry that wallet someplace other than your back pocket.

Sitting on your wallet throws your pelvis out of alignment, compressing one side of your back and overstretching the other side. It can cause an impingement of your Piriformis muscle, which can put too much pressure on your Sciatic nerve, causing back, hip, knee, and leg problems.

Try switching to the front pocket, carry a bag, or remove your wallet if you’re going to be sitting more than a few minutes.

How about a nice alligator purse?
