Rubber bands are also good but still...will never give you development like a Good bench, squat stands, barbell Dumbbells. I still have a bullworker will make a photo tomorrow it´s in my basement. I even have old school iron boots !well yes it has an element of both, which makes it superior to a fixed device,
