For those of you who remember the old rec.motorcycle.dirt news group (and I know a few of you used to hang out on there) this should come as no surprise. A fellow called Doc Wu (he really was a doctor) used to spam the group saying he could make you a faster, better rider. When cornered he just said "stand up".
Of course trials riders have known this for years.
