Ok, enough with unorthodox pullup methods =D
now for some advanced stuff for you crazy buff people to try out!

First and foremost, the Muscle Up!
rated as supremely difficult, its just a grip technique essentially...


a fast twitch pull up:
the CLAPPING pullup!
you've to be able to pull up very fast, and propel yourself a second over the bar, with the burst of speed keeping your arms redundant, enough time for you to CLAP =D


Next, the One HAND pull up
not much different from the strength required in a 2 hand pull up
but it greatly trains your GRIP and your Biceps as weight is shifted over to the pulling arm.


and the one ARM pull up
the real deal, its a strength move. no technique, no momentum can help you
you're greatly off balance and its only strength that will propel you up.
Behold =D


Next, the Front Lever
extremely taxing on the core and entire back.
its like doing a bench pull with your bodyweight, PLUS maintaining the balance, with your entire lower body's downward pull being countered by your core muscles
the trick is to pull your shoulder blades backwards and your arms pressing down towards the bar. so as to straighten the back and even out the Center of gravity respectively.


Lastly, the Human Flag.
this move is supported predominantly by your LOWER arm. the upper arm is for balance.
first, get your arms into place. then, when you kick off, use your lower arm to PUSH HARD against the bar, and you'll get into place =) a lot of core conditioning is required to get your body full out straight.
and here you go, guiness book of record. 39 secs!


DISCLAIMER: all those people with upcoming competitions please do NOT overstrain nor TRY these moves if you're unconfident of the result! when i did the clapping pull up at first, i tore the skin off my entire palm with the friction it generated. so yea, at your own discretion =) be careful!
