Sea Legs are Normal

I found out this morning from a coworker that sea legs are normal for everyone who uses a treadmill. Thank Goodness! So it's not just me, and it has nothing to do with the MonSter. He said that he's been using a treadmill for years, and he still gets that feeling everytime he stops. He said that it does get better the more that you do it - not as severe, and goes away quicker.
