Ok SF, dispute with GP now. Now here is a Super Moderator saying you are wrong about non-isolation capabilites. Again, you prove something for ONCE! Thanks GP, this non-rook, but non-smart, probably low-paid trainer to old ladie, will not listen to anyone ever. He is just so much smarter than everyone he thinks but all he does he say everyone is wrong and he can proved it, which he never does. And I do not have the specific experience the GP has 20 years of bbing and training, but I have been in the Army for over 20 years responsible to train soldiers to be in top physical condition. This is a condition which is way beyond the condition of bbers (no disrespect to anyone), but this is hardcore, carry your buddy for two miles on your back while being shot and your ruck is on your back also after fighting for hours on end. Its carrying 150 lbs on your back for hours on end just to get to the fight and then fighting hand to hand in the dark. So I think I know a little about training people to be in phenomonal shape. SF, go back to Boca Vista and train Mr and Mrs Seinfeld.
