I'm thinking of signing up for a Krav Maga class soon.
Where do they offer these classes?
Often leisure centres and gyms - it's a kind of military self-defence and fighting system so anywhere where they do karate etc.
Is there a progression training system and does it focus on close range combat?  Or do you use guns?
No guns but it's known for it's focus on real-world situations and extreme efficiency.
Would it be something I can put my child in?  Rather than putting them through karate class, can they sign up for Krav Maga or would they need to be a bit older?
Yes I think so. It comes from Israel and mixes skills from boxing, wrestling, judo and karate - so really handy and great exercise.
