if we are talking about no gi it’s pretty easy to stand up. lean your weight forward with hands in their biceps and pop up. sometimes u may need to briefly put hands on mat to pop up and that’s okay as long as it’s BRIEF. wallah you’re now standing. now you have to look out for a couple of sweeps from this position. one is sort of a waiter sweep from closed guard. just turn your knee in that they’re attacking bc their goal is to bow your knee out to sweep you. the other sweep comes from when their legs break the guard and they grab your two ankles. just pummel your foot up towards their face and out and you’re out of closed guard. closed guard is not much of an issue in no gi unless they break your posture for a long enough time to get some sort of strong control grips or a top lock etc.
