Start making madmans tut to read.
1.First of all whats a madman?
A madman is when you make more than 5 dismemberments.
2.How to make it (my best way)
The best way for me to make a madman is to dismemeber the mid section "lumbar,Chest" because if you got this you already broke the strongest part of uke and also its better because you get alot more movement because you only have to drag the upper or lower body trought the room.
So at first you should start whit a kick to the midsection and break Uke in 2 pices after you did this you can focus at the lower part of uke "legs,hips" or focus on the upper body "head,breast,chest,arms" after you choose one of them i would say take the upper body its easier focus on the next part that you want to break the best way is to start whit the head you can also try to get a powerfull kick between the pecs that could break a arm or if the kick/punch is powerfull enought it could give you a boomhit what means 1 hit 3 dismemberments if you get the boom hit you are done whit the madman if not try to kick,punch or rip the head of that would be the 2 dismemberment after you got the head you just have to punch /set hand on grab for more damange/ the pecs and you will get another dismemberment and you will have 4 or maby 5 dismemberment and youve done a madman .
didnt that sound easy ..it is just need to try.
