Are you in shape?

Many people are fairly confident in their physical fitness -- whether or not that confidence is justified is another question. Just because you're thin, you could run 2 miles a couple of years ago, or you can run half a block to catch the bus without feeling winded, doesn't mean you're in shape. How do you tell if you're in shape? Well, you could take this quiz, but frankly, I think it's a bit sparse -- I scored 'Fit and a Fiddle', even though I definitely have strides to make in the physical fitness department.

If you want to know how fit you are, I suggest seeing a personal trainer. But if you ask me, if you can't do the following things, you're not in shape:

• Run a mile without stopping
• Pass Dr. Oz's Push-up Test
• Do 50 sit-ups or crunches

What do you think? Are there certain other fitness markers that divide the in-shape from the rest of us?
