Basically, what strength moves look impressive.

So far I have

anything Planche related
One armed push ups
One armed elbow lever
Dragon Flag
90 degree push ups
Free standing hand stand push ups
2 finger push ups bruce lee stlye
Human flag
muscle ups
hollow back

What else are there

not saying i can do these
i can only do the first two on this list
the rest are my goals

xD id like to see a video.. to entertain myself

youtube them

run around in circles with your shirt off with a boombox blasting "run around the room, run around the room"

Only thing I've got for you is hollowback and muscle ups. The second one is relatively easy if you're fit, but most people these days aren't.

Muscle ups are hard when your just learning

Ah thanks
I forgot about muscle ups

and I can already do planche/one armed push ups, the rest are just my goal. I can also do two armed elbow levers (they were part of my planche progression). Close to dragon flags, and I can do handstand push ups just not free standing yet - I have the strength just not the balance for a handstand

also hollowbacks look sweet, definitely gonna learn those, thanks.

actually after watching more bboy moves i'm just gonna teach myself to breakdance now

Chinese Push ups, done a lot of them on Kung-fu training...Hurts.
Horse stance - Used in Wushu but also Hongar Kung-Fu.

horse stance doesnt look too impressive imo
chinese push ups yeah those are intense, im working my way towards one and im fairly close

Considering people are able to stand in that possition for more than like an hour, I would say it's pretty damn impressive as i barely make up for 5 minutes...
