I weigh 180 lbs. This is simply for cardio at home, I box at a gym twice a week as well.80lb is less than 6 stone, it will probably hang of most things, try swinging off the beam or truss yourself first. What weight are you?
Are you going to practising hitting people that are less than 6 stone ? doesn't seem very ambitious
