Dude, if you can do anything else after Legs, then you didn't do legs properly. Leave Legs on a day by itself. Put Shoulders after Legs.

What's the takeaway in asking this? It all depends on how you feel. Sometimes you can train whole week without adverse effects. Sometimes, twice a week shall suffice.

As for me, I train at least 4 times a week.

Pretty insightful (depends on how you interpret it, of course) and interesting take on Pre and Post nutrition.

Looks like I'll be carrying around Gummy Bears in the gym...

So what if the other side is not up to par with your dominant side? Just hit it with the same intensity if not more to make up the deficit.
