I'm having trouble with some guys standing straight up out of my New York bagger. I know it is not my leg curl strength because when they pick me up im chest to chest and still am hugging the knee. What it is is just that I don't weigh much (around 150-165 depending on the weather) and some of our guys just have strong backs or something I guess. But it is irritating cuz that makes rubber guard and closed guard in general useless. Now normally when a dude stands up i just open my guard, or try to sweep is legs but shit when Im in New York bagger Im playing rubber guard and wouldn't expect someone to do that, but there are a few that do. Anyhow anyway i can stop this?
