Plank is in as a permanent alternative to the leg tuck

My DS and I would regularly do planks during the commercials when watching TV when he was in High School.
A 2-minute plank is so easy for me that I can start to think "I'm still in good enough shape to hang with some Army type."

That leg tuck thing though? No way.
 
That's funny. I don't care who ya are.
