can easily give to a younger athlete
1.
ABSOLUTLY SERIOUS WHEN I SAY ..............
BOLT one of first teenagers to heavily benefit from this.
all takes is afew nice little cycles to push developement
in training and importantly
the cycle to peak at major champs .
not doing anything about him , or when full of steroids .
when real stellar combo .
2.
many other examples maybe later teens .....GEMILLI .....
recent 100m world junior champ
and the very obvious
ANYTHING TO DO WITH HIGH HURDLES AND FOOT SPEED
the last two sub 13 in underage hurdles stickout
so much and where IGF really works its magic .
no secret why taller sprinters are in high demand
where most damage can be done with added cadence at peak.
IAAF KNOW THAT
IGF-1 LR3 IS ALL OVER SPRINTS and so obvious
that all over handful of younger athletes now , where biggest
gains can be had and for future .
nice little groups in usa ,france and obviously hands
down winner jamaica .
