Jump into Foundation One or Finish Perfecting 6 pre-FSP's?

I can do 3x60sec for 4 of the 6 pre-FSP's (plank, reverse plank, top of dip hold and pullup hang; still need to perfect hollow and superman).  Should I finish off completing 3x60sec for the last two or skip em' and jump to Foundation One?

 

Any suggestions?

Jump to Foundation One. The more sophisticated approach to training prerequisites coupled with the integrated mobility work in Foundation One will certainly yield better and faster results than what you are doing now.

There is no doubt that F1 is the way to go here

F1.

All,

 

Thanks for the quick replies.  It's unanimous, so off to F1 I go...
