providing myself as a case study.
i am not a pure bodybuilder, but i love doing it and use it for effective strength gain.
my sport also involves a lot of stress on the calves eg. skipping, running, sprint intervals, plyos, etc.
i spend a lot of time on the toes, especially whilst training for comp.
considering that i weigh about 230lbs when in peak shape there is obviously a great deal of stress on my calves every day in training camp.
i have doms every day during this period. sometimes i can't even walk in the morning until some blood gets in there.
guess what happens when i train like this? my calves get smaller.
what happens when i do less and continue weight training them about once a week very briefly? they get bigger.
oh, btw, if i eat more than i need whilst in training camp i just get fatter. so much for the doms plus 'eat more' theory.
recovery is a huge part of the picture and every athlete and trainer knows this. for some 66yr old fat man that can't even chin his own bodyweight to say that overtraining doesn't exist just proves he's talking out of his ass. to say that one can gain CONTINUOUSLY on his program without any regard for size, sex, hormones, mindset, musculo skeletal system, genetics, recovery is beyond ignorant. the man is obtuse.
he has made the statement earlier that doms plus extra food = anabolism. that's his 'theory'

there is absolutely no scientific/anecdotal evidence at all to back that up (i challenge ANYONE to prove otherwise) and, in fact, neither he or any subject has actually tested it.
