For the guys that put on a lot of muscle and increased the weight they could lift over the course of a few months or a year I have a question - were you sore most of the time after your workouts during that mass gaining phase ?
What about when you hit a plateau - were you still sore ?
Also has anybody gained a lot of mass and muscle but _not_ been sore after workouts ?
I'm trying to figure out if not being sore means you may not be gaining. There is some theory that suggests muscles get sore because they are expanding, eg sucking in water and nutrients and reinforcing. ( Note lactic acid was for a long time was thought to cause delayed soreness but this has been shown to be false recently. See wikipedia for details ).
