You take the bands and attach them to the ends of the bar and attach the other other end of the band to a heavy dumbell. Make sure the tension is tight and bench . . . .
HAHHAHAHAHAH ... couple of things. First I'm a guy, and the name is a joke. Second, I was asking how to attach the dman things. I know what they do, I know how to attach them. I was just looking for tips on how to integrate them with my bench press. Do I do them one week instead of my bench, or do them on speed bench day?
