Use an out of date phone book or two to make a step for step aerobics. Wrap one or more books with duct tape to make a firm step.

You can make your new step a little prettier by using colored duct tape and wrapping it in color-blocked stripes.

If your step slides out from under you it’s an easy fix. Glue or tape strips cut from an old mouse pad to the bottom of the book after wrapping it with duct tape.
