Hi,
I hit the wall trying this method for several weeks.
For me it seems that 2 warmup's is the best way to achieve my limit.
To days ago I did a try with 2 warmups for the first time for a while and I did a new dry pb of 6'16''.
There are so many variables that affects a breathhold so I can just say that with my breathup etc. today this is the best....
Doing static's without warmup's can be a good training though...
