When will I need Foundation2?

Hello, 

i currently am using foundation 1.   On 5 of the elements I'm on exercise 1,2 or 3.   However, on side lever and hollow back press I'm on the 6th exercise in the progression (and can do step 6 of HBP easily).   My question is, when will I need to get foundation 2??

thanks, 

Chris

Foundation 2 begins after the 6th progression in each F1 category.

Thank you.  I thought I was ready to move on on the HBP.  

If you have mastered any of the F1 exercises then you should progress to Foundations 2 for the specific exercise.

Thanks guys.
