To begin with, I must say that duration of workout on one particular muscle
group, will not necessarily maximise its size. The muscle require rest,
diet... and also exercise in order to grow.

I'd say "no", but obviously there are some effects (in terms of body
resources). Soreness of muscles is the cause of breakage of fibre, not

The longer and more frequently you work out, the better your inter-workout
recovery time becomes. I am not sure about intra-workout recovery, but I
think it's also affected positively.
