integrated mobility for planche

can anybody help me, what should be the integrated mobility for the tuck planche , adv.tuck planche and straddle planche?

my planche progression is going very very slow, i follow the coach sommer article "Building An Olympic Body Through Bodyweight Conditioning". where as i have almost done front lever hold and adv.tuck front lever row but my tuck planche hold is not going more then 25s-30s. Now, what should i do for increase the time limit of tuck planche hold? if i insert integrated mobility in my routine then definitely it work very fast.

Lee that article is fairly old, written when Coach Sommer was just beginning to work with adults having little or no gymnastics background.

 

He has since revised things, and come out with the definitive adult GST training guide - The Foundation series. Which will take you from step one forward to straddle planche. 

 

We've also seen that students having a tuck PL often have enormous holes in their training, so we strongly recommend you start with Foundation One and work up. This will also answer all your iM questions.
