Paper or plastic? Both can work for a dollar-store version of the Gliding Sliding Disc. “Paper plate exercises work best on a non-carpeted indoor surface,” says Syd Hoffmann, health and wellness expert and author of All Day Energy. “Start with lunges -- side, back, front, diagonal lunges, curtsy lunges behind -- with one paper plate under the foot that is moving.” Instead of stepping into the lunge positions, you slide the foot in and out -- you’ll add a new stability challenge to your workouts while toning your lower body. More advanced exercisers can try hover jacks: Assuming a “plank” position (which is like the “up” part of a pushup), with plates under both feet, simultaneously slide the feet apart and back together for an inner/outer thigh blast.
