Nowadays I cannot go to the gym more than once a week. Not beacuse I have no time - I am just simply tired after work, it's cold and dark outside, sometimes I have a headache, sometimes there is something good in the TV etc-etc. So even if a try to go more frequently, finally there is always a week between my workouts. So i train chest, shoulders, biceps one day, one week later back and tris, one week later chest etc. again. And legs... well maybe once a months. And I look the same as when I trained 3 times a week.
I am a lifetime natural, so after all I am only hard, pumped, vascular when I am in the gym, so it doesn't matter... And at least I can be sure that my muscles regenerate.
