MADISON (WKOW) -- Getting in shape for the summer and that bathing suit, can be a challenge. But, it's doable. Especially, if you incorporate lunges into your workout routine. While they're not easy, they are effective, and cheap. You don't need a gym to do them. You can basically do them anywhere. Wednesday morning, Kat Manuse from the Dane County YMCA showed our own Elishah Oesch how to properly do lunges.
