Got swept all over the place by a four stripe white belt with less weight but more strength than me just the other day. I'm about 250 at six feet, with great big legs. This guy had a phenomenal (at least as far as I could tell) hip bump that, even when I managed to bridge him over out of mount, put me right back on my back a number of times. Against another guy my size, I got scissor swept right into bottom mount. Both of those were eye openers for me, and they seem to be sweeps from guard that are favored by the bigger guys in the gym. Are these good ones for me to focus on at this very early stage of my training? And are there any other basic sweeps (half guard would be appreciated too!) that you could recommend to me? Thanks, everybody!
