Welcome to the GitFit Guys' quick and dirty tips to slim down and shape up.

My name is Ben Greenfield. I'm the Get Fit Guy, and in today's episode, you're going to learn about

three exercise trends that may actually be bad for you, even though you thought they were good

or to burn more calories. But Jeff interviews an expert who says that research studies show

these things don't actually engage your core any more than a chair does. And they can actually

increase compression on your low back
