So as not to leave you both hanging,
it is suggested that you take a 5 minute break
after 25 minutes of PR. The suggestion
is to use the break for something other than PR.
It is also suggested that you take a
drink of water at the break since PR tends to dehydrate
your brain.
I may have the timing off slightly, but
it is pretty close to the suggestion.
I am quoting Alex here and if there is something
wrong or missing, it is my fault.
I'm sure someone will add to this or correct
me soon.
