For PES BP Rec, u have to request before BMT starts because PES
BP BMT is kind of structured, which means training is stretch thru
out the whole BMT period meaning training such as arms training is
introduce very early so there is no such thing as a "exercise"
period then BMT period for PES BP Rec.
Once started, u cannot get out of PES BP BMT training even u get
IPPT gold/sliver. (How I know? I was once PES BP and there were fit
dudes who lost weight before BMT in our company, they lan lan
served with us for the whole PES BP training period.)
