The Move: Seated Diamonds
While you're working your inner and outer thighs, why not tone your core, glutes, quads and hamstrings? This compound exercise targets pretty much everything at once, says Zerling. And the only equipment required is a chair...and a TV with prerecorded episodes of Scandal to distract you from the burn.
1. Sit tall at the edge of a chair. Extend your legs in front of you, then bend your knees and pull your feet in, pressing the soles together.
2. While holding onto the sides of the chair, use the strength of your core to pull the knees out and the heels toward your groin as you create a diamond shape with your legs.
3. Squeeze your inner thighs at the top of the exercise, and then extend your legs out in front of you, keeping your feet off the ground.
4. Reps: 15.
