The ProsourceFit Pilates Resistance Ring adds a new challenge and heightened strength-training to classic Pilates mat workouts. The lightweight circle provides gentle resistance to help tone your core, as well as the small, hard-to-target muscles through-out your entire body. The unique design is ideal for rehabilitation exercises, those new to working out and learning to activate the proper muscles during workouts, and anyone who wants to progress in their Pilates practice. The 14-inch toning ring helps improve balance and causes muscles to adapt and become stronger, making it great for both general conditioning and physical therapy. Foam handles on each side make it comfortable to hold in your hands or between the feet or knees. It's perfect for gently toning thighs, arms, back, chest, and core while doing exercises like bridges, boat pose, roll-ups, side presses and much more. The sturdy steel “magic circle” is covered in durable rubber, so you can twist, turn, and squeeze it, yet the shape will hold. Available in 4 colors, suitable for men and women. .
