Type: Inversion machine health equipment. The shin pads have peeled off, so I've made replacements by hand. Originally, they were the same blue pads as the calf side, but since I changed them to handmade ones, they are more stable and cause no pain. The appearance is not great, but the strength is definitely there, so there's no problem hanging from it for pull-ups, and it allows for more effective abdominal muscle training.
