like BOLT and GAY ! these 2 sprinter get a bad start this year, Nevertheless they are powerful ! They should change trainer ?
the START is very complicated, very technical, it's not only POWER, POWER, POWER, look CHAMBERS, look AIKINES ARYEETEY, they are not better than christophe this year !
In Helsinki, Christophe ran first 60 in 6.56 with wet track, cold and wind (-0.7), it's a good time for him, he can run sub 6.50, this year with good condition and especially with warm temperatures.
In Paris, Christophe ran first 60M in 6.58 with cool temperature (17°c) and a reaction time 0.190 (very bad), with a normal reaction time (0.140) he could run 6.53-6.54, , Christophe is ONLY 22 years old !
The trainer of MARTIAL M'BANDJOCK (french sprinter) is MAURICE GREEN (world record holder on 60M), and this french sprinter is not more successful than when he trained in France !
There is no magic method, Christophe has to train again and again ! BE PATIENT
