According to a 2003 Chinese study I read that is….
The study says men will have significant jumps in testosterone levels from looking at sexually arousing material.
It went on to say that “viewing sexually arousing material, without ejaculating, before working out should be beneficial for improving workouts.”
Bad news though – it also says “ejaculating before working out, would probably not be ideal, since ejaculation also releases endorphin natural hormones in the body. This would in turn affect your strength and energy before your workout.”
So the lesson here – is to check out shemuscleraw before you workout to help gains.
