Quick exercise move

I realized yesterday I hadn't done butt clenches in a while. As the name suggests, you clench your butt to the count of 5, release, and repeat. The article I picked it up from suggested doing it every hour when you're in the office (10 reps, then 20 quick clenches) or when your car comes to a halt when you're stuck in traffic. Either way, it makes you feel worked out, so thumbs up from me!
