After doing my back I stopped all training and became a fat weak bastard, I'm getting back into it slowly using GVT 3 days and pt 5 days, I've lost 8 kg since Xmas so I'm down to just under 80 kg now.
Power lifting is out though as my back won't take the load anymore.
I'm popping multi vitamins, taking in some extra protein, cutting out bread and other shit carbs and drinking a heap of water.
So far so good, I'm not feeling to shabby for a 46 yr old.
