Serge do you believe it is good to train a muscle while it is still sore? how much of a factor is heredity/genetics?
For me train a muscle when it is sore is the best training, because you realy feel this muscle, I love it. Yes herdity/genetic is important but you have more important than that, it is the 3 powers. That means YOUR MENTAL POWER - YOUR LOVE FOR WHAT YOU ARE DOING - AND YOUR PHYSIC, which is the less important one, because it depends of the 2 first POWERS chich come from your inside.
You can have the best physic ever, if you stay home, you will never progress, but if in the begining your physic was not exeptional, but you have the love and the mind with you to go the gym every day for hours, than the result will be there too.
