Nope, You use the bag at half of your weight. usually the standard that seems to fit for everyone is the 100 lb heavybag, however girls at my gym typically use lower sizes and smaller bags at 75 or even 50 lbs. Do you know how hard it would be to sink in a 200 lb heavybag filed with sand? It's pretty much impossible for I assume except for probably 1 in a million boxers. So nothing over 120 lbs. because if I remember in science how density works, yow, he's gonna break his hand if he's being serious.
