I've seen several of these appear in old photos could someone shed light on the name and use of this piece of equipment. I haven't any photos of the item in question Ive seen multiple of Jack Johnson using them passed around if that helps.

Some trainers do not approve of the pulleys or the push-ups. They believe those forms of exercise tend to make you muscle-bound. I approve of them, unless you already are heavily muscled in the shoulders and arms.' Jack Dempsey, Championship Fighting.
