The Thigh Twister
A simple but brutal device, users stood on a platform and gripped handles while twisting their lower bodies side to side. It promised to trim the thighs and hips with minimal effort.
The twisting motion, however, put intense strain on knees and lower back, causing sprains and chronic pain. Many users gave up after feeling sore or injured. The thigh twister is now remembered as a painful gimmick rather than an effective fitness tool.
