I'm kind of overweight, and a little older than most here (around 30). Is this for me? Looking to lose a little weight..but also learn a very solid self-defense art. Not looking for combat sport, just something where I can take care of myself and my loved ones. I have already emailed the instructor of the school, about the classes, and anything else that I would need to know? Anyone own one of those hebrew krav maga sweatshirts?
