Hello A few years ago I had to give up Muay Thai due to a problem with my back. Hundreds of knees, kicks, punches and elbows every session were too high impact for the compressed discs in my lower spine. Reluctantly I sought a new art/system that meant that I wouldn't have to relearn too much and after some research I started Krav Maga. I found the techniques easy to pick up and although there was still a significant amount of striking, it was much less intense and my back has been fine. However, I'm beginning to question its usefullness. Everything is very staged and scenario based, at half speed and without wishing to sound offensive, the majority of the time the people you train with are more of a hinderance than a help. Last weekend, I was nearly involved in an incident in a pub which I successfully talked down but afterwards I realised that, in my Muay Thai days, if events had taken a turn for the worse I would have not hesitated and finished the job. Now, after training twice a week in Krav, I felt I didn't have a clue what to do, mainly because I've spent the last two years pretending to hit someone or disarming a kidnapper with a gun and then disarming him and mowing the room down with his plastic gun. It all just seems a bit too pretend to me. I've condisidered doing mma but I'm 40 now and possibly a bit too injured for the intensity. Does anyone has any advice or recommendations with regard to a suitable art? I like striking and ground work and realistic sparring. A friend of mine trains in Silat. What are people's thoughts on that? Thanks very much for your help.
