Light cardio won't hurt, but your rest days are meant to be rest days. Maybe a few pushups and pullups or whatever won't hurt, but don't go lifting heavy.
What Ka0s said will work for light weights, but what about when he progresses into heavier weights? It'd be best to follow the instructions from the guy who wrote the program, yes?
It's not as if when you're bulk is over, you'll suddenly see fat hanging off your belly. If you're gaining too much fat, then you'll know, since it's a pretty damn gradual thing.
Follow what he says, or follow what Rippetoe (the guy who wrote the program) says. I'm not saying that what Ka0s said is "wrong" per se since it might work, but one of the options is better.
Ka0s is "wrong". That's not how you're supposed to warmup for SS. I mean, that idea could work for such light weights, but if I'm squatting 300lbs, I'm gonna warm up the way Rippetoe says to warmup....
Keep in mind you cannot gain muscle mass and loose weight at the same time. One involves eating a calorie deficiency, while the other requires a calorie excess.
It's recommended to work through soreness. Unless it's crippling DOMS, you should be working out if you're sore. Go a bit light, but the extra blood flow will help recovery.
P90x is only a cutting program if you're cutting. You may not be gaining mass, but you certainly won't get smaller if you're eating more calories then you're burning.
NO. A beginner should NOT be sweating or pushing themself to get through it. You're supposed to start off light with SS, to reduce initial DOMS and prevent premature stalling. Again, you aren't...
