quad stretch in 7-min warmup

My attempt at the quad stretch in the 7-min warmup is pretty laughable.  I try to hold PPT as I go down, but my quads are far stronger than my abs.  I'm doing the FS series weekly, but I know that it will take many months to improve.  Is there anything else I can be doing to improve quad/hip flexor flexibility?  I think it also affects my table.

Hi Gary, it simply took a lot of time...no shortcut here.

Progress!!!
