I checked Mass.gov and saw the video. They don't mention how much the bag weighs. From what I've read here the dusty floor seems to be a problem when doing the cones. I'm just curious to now how much the heavy bag weighs and if they add weight to it? So it's one of the last obstacles in the course. I saw that the guy went head on to the bag and touched the floor with it. Then u have a seperate event, which is timed, where you have to pull the bag away. What is the best approach/technique to pull the bag over the line? Should you worry about getting both feet over the line first? Thanks for any input!
