Ginastica is a brilliant way to warm up and stretch or even work out with actions relating to bjj. I love this stuff and first started trying to pick up some technique from watching a few videos, and then did a seminar with Xande and he showed some simple ways to use it as a quick warm up. I get our kids to do a little and they love the motions. A lot of it helps you program certain flow and reactions into your body mechanics which I find really help with bjj. I'm still a Ginastica white belt, but I've got one of the dvds and I'm hoping to blend more of it into my warmup style because the little I've learnt has had a huge positive impact on me
