A waist twisting disc, also known as a waist twister or a waist rotation disc, is a piece of exercise equipment designed to help improve core strength, flexibility, and balance. It typically consists of a round, flat disc with a non-slip surface, often with handles for stability. The user stands on the disc and rotates their torso from side to side, engaging the muscles of the abdomen, obliques, and lower back.

The twisting motion targets the muscles around the waist, helping to tone and strengthen them. It can also aid in improving spinal mobility and flexibility. Additionally, using a waist twisting disc can enhance coordination and balance, as the user must stabilize themselves while rotating.

Waist twisting discs are often used as part of a comprehensive fitness routine, alongside other exercises targeting the core and lower body.
