I practice Aikido, and I believe you shouldn't underestimate it. Now I know you may be thinking, "Why take a weakling martial art like Aikido seriously when I am learning Kendo?" I can see why you would think that, how can a peaceful martial arts like Aikido beat a powerful one like Kendo?
Well, I have a story to share with you.
Years ago, I was a Kendoka, I thought I was the toughest kid in high school, I would pick fights, and kick ass. I was full of hate, until I picked a fight with the wrong dude. He was a Japanese exchange student, I still remember his name, Noboru Takeda.
I picked on him because of his hilarious and thick Japanese accent. I told him I was going to beat him so hard, he would go back to China(Yeah, I was a little racist prick.), he never said anything back, made me wanted to kick his ass even harder.
Well, here comes the fight. I threw men and do strikes, he dodged them like I was a mere white belt. I was tiring out and he knew, I saw the smirk on his face that made me raged hard. I put all my strength in one amazing tsuki, and he grabbed past it to my wrist and threw me over. My back smacked on the hard cement ground, and I was knocked out for who knows how long.
When I woke up I was in the school infirmary, I asked the nurse who brought me here, and you guessed it, Noboru Takeda. The next day, he wasn't at school, he was back in Japan, and I never got to thank him, for saving my life and showing me the light. I soon learned that he was an Aikidoka and have been practicing Aikido ever since to show my thanks to him.
I have defeated countless opponents using Aikido, and they always ask me, Why are you so strong?
I answer, I'm not strong, you are.
Aikido uses the strength of the attacker back at them but 10 times stronger(estimate). Using Aikido and I can probably kill a charging Rhino using it's force right back at it, of course, I'm not going to try it, way to dangerous for any sane person.
I recommend practicing Aikido for everyone here, as you are all physically weak, and Aikido is specialized for the weak to defend against the strong.

A 50 year old man with cerebral palsy doing Aikido, very touching.
Arguably the most powerful martial arts in Japan.
An Aikido practitioner is practically invincible, no one of any martial arts background can ever land a punch or kick on one.
Using the power of the attacker, the Aikido practitioner uses absolutely no energy to knock them down.
A fearsome martial arts it is.
