I've been training Muay Thai for about 6 weeks now, and I've done a lot of partner-based drills and whatnot, but I haven't really done much with the heavy bags. I would like to buy a heavy bag for home use, but I'm not really sure what size I should get. I've seen 40, 60, and 100 pound models, but they all look the same, in terms of dimensions (granted, I have only looked online, and not actually in-store). If that's the case, I would think that the lighter ones would just sway more when hit (which wouldn't necessarily be bad, especially for practicing teeps). I'm thinking a 100 pound bag would be too unwieldy for home usage, but I honestly don't know. Anyone have any suggestions for me?
