Can I work my abs out EVERY day?

Your muscles are all made of the same tissue, even the abs.

Think about it this way... you walk every day, you talk every day, you climb stairs, type, carry kids, and move around every day. Your body was designed to move and be active every day, so it is also okay to do abs exercises every day.

Here a clarification.

If you exercise any muscle intensely, you should rest it the next day, especially if you are sore. But if you are doing light exercise and you are highly conditioned (used to the exercise or activity), it is okay to exercise muscles every day.
