weightlifting hangover

6.10:

. a reason for weightlifting hangover is that

while an extreme amount of exercise can replace insulin's function,

conversely, it may tend to temporarily decrease insulin sensitivity;

ie, insulin is spurring the cells a bit,

and then after exercise spurrs the cells a lot,

insulin's kick just isn't noticed as much .

. that may be yet another reason why stretching is magic:

not only does it do more ripping an damage that requires growth,

it also involves on-going exercise -- more cellular spurring .

. conversely,

perhaps any vigorous aerobics after weightlifting

might be a replacement for stretching?
