So I've got a 'problem' with my BJJ game. I suck at armbars. I bring this up because as a white belt rolling I'm struggling at a lot of things, which is a given. But one odd issue I've been having is doing things when I do get to full mount top. I can maintain mount fine, but I feel like I'm stalling myself out when I get there and can't do a lot before the other guy calms down and catches me in a sweep. I don't want rolling to me 4+ minutes of me tryin to keep my balance mounted. I percieve that armbar from mount is one of the most common attcks while mounted. But like I said, I suck at it. My instructor taught it to me one day, and just told me to keep repping it on the dummy. But that aside I've gotten little instruction in that dept. Here's what I know and can do while mounted so far. 1. Arm bar - don't get chance with that unless the guy puts up his arm, and even then I'm having a lot of trouble executing the technique (I feel like Damein Maia at UFC 118 all the time. I get it, I kinda do it, but can never finish it) 2. Americana - had a little success, but the issue there is getting the guy's arm to the mat. Usually I try putting my weight into on arm to free it up, but am just not "strong" enough to get the arm. 3. Arm Triangle - haven't had much of a chance. My one instructor taught us an unorthodox set up for it, which I rarely can get a chace to attempt. Don't know any 'conventional' set ups for it. 4. Omaplata - sick move, same unorthodox setup, but there's no way I'm hitting that so soon. (I have vowed though that one day I WILL hit and finish someone with an omaplata in competition.) 5. Triangle Choke -Had some success with this. Only can get it if I move the mount up high and wait for a chance to get the one leg over the arm. Biggest issue is sinching it up. Is there anything else I can do, or recomendations to improve what I already know?
