HEAVY BAG/MUAY THAI HEAVY BAG I'm moving and ideally want to hang a muay thai heavy bag(6ft. 100lbs.) up in my garage. if not then definately a standard "boxing" heavybag. anybody know enough or have any experience where this caused problems with their house? any support beam stronger than another? the last thing i want to do is cause thousands of dollars of damage when it could have been prevented since im not moving anytime soon.
