Yeah, I dont like warm ups that go to far, students wont learn if they are to tired to think. That again means they will get less out of the training. Exhausting before sparring is great, but not before trying to learn something new.
Alot from aikido is well suited for real life scenarios(I know, I use it often in my job), but like any other art its about finding what works best. That krav maga took so much from aikido is great in my book, just show the battlefield past of it still works in these days

For one we have the mass training(3-5 opponents),wich I love, where we have to foucs on several opponents at once. And many krav maga schools do the same.
Most people seem to think the flips we do are how the move is supposed to look, but we do those flips as the locks themselves are designed to break limbs. so the flips are for selfpreservation purposes(and they look AWESOME in demos ofc)
Actually, there are schools that have gone back to those roots(from peaceful to warrior attitude)and you would be surpised how much similar to krav maga it actually is. We do have strikes, but how they are used is different from school to school(peaceful/warrior).
Personally, since I began training, I became more confident and less scared of unarmed attacks, blunt weapons and guns.
But knives have started to scare the living shit out of me. I realized how hard it is to survive those attacks even when you see them coming. Let alone when they're unexpected, and let alone leaving unharmed.
Yesterday, when I was chopping onions, the knife slipped out of my hand and fell on the ground. I backed off as if a I dropped a bomb.
Weird.
I have been attacked with knives(twice), and I have scars and a thumb with no sensation, and I have had a gun to my head. Knife was one thing, but few things are as terrifying as having a barrel pointed at your skull point blank. It was a .22 ruger, nontheless it would be more then enough to kill me. It takes a special personality to try to outrun a bullet without thinking. I froze completely, and chances are most will unless conditioned to act on it.
Thing about knives, you have to accept you wont get away unharmed. Might sound pessimistic, but its the truth. Have you tried training with markers? We did that, and 90% of the time, you will get a mark somewhere,meaning you got cut.
If you get away unharmed that awesome, just accept that when someone swings a blade,chances are you will get cut. Point is to get away alive.
Didnt do aikido back then btw.
