I'm more a kick boxing kind of guy but recently I started training with some friends in bjj. And while my defensive skills are improving, I have a hard time on the offensive part. In kick boxing I can watch a technique and then practice it until I get the hang of it but in bjj it feels like setting up the right situation to use a technique is much harder. I think that it would be better for me to learn the levers of the human body I can use. So if you can share how to grab and twist some limbs or even better if you have link to a video, I'd be able to kick some azz.
