Using Key Pilates & Barre Principles along with the Pilates Mini Ball to Tone the Inner Thighs which are so often neglected in favour of the Glutes. Here we focus on the Zipping up the Core and toning the Inner Thighs & Side Waist. I love this series, it creeps up on you, and by the end I hope you feel completely uplifted. If you're without the Ball, try folding a small pillow in half, or just go without.
