Ok I started Lifting weights. Which I really not use to so I'm starting real low and building myself up. I worked out for about 20 min yesterday and now im a little sore in the shoulders and my bisep area. Its not real sore but sore enought where it makes you weak lifting weights. Should I lift while being sore? or wait until my soreness goes a way and lift then.
I heard you should wait until your soreness goes away because itll damage you muscle or some stuff workign out while your sore..
so any info would be great
Thanks alot
Billy

In general, it's not a good idea to train a muscle group more than once a week or you run the risk of overtraining them. Basically, when you lift weights, you're actually tearing the muscles. The muscles then need to repair them selves, and they do so slightly bigger than before incase you need to lift the same weight again. If you don't give them time to repair them selves, they'll just get fatigued from being constantly torn without being able to repair. The time they repair them selves most efficiently is when you're asleep which is why it's important to get at least 7-8 hours sleep a night if you want to make significant muscle gains, along with eating correctly obviously. High protein, low fat works best for me, with 4-5 days low-moderate (mostly complex) carbs followed by 2-3 days moderate-high carbs a week.

If you're doing a 3 day split, a good place to start might be:
Monday: Chest, Triceps, Abs
Wednesday: Back, Biceps, Calves
Friday: Shoulders, Quads, Hamstrings

spending about 1-1.5 hours working out each day.

Only do a short cardio warm up on these days and do any intense cardio work on others. As you get used to doing the same routine, you'll probably stop growing which is when you need to change it to make your body grow.

Hope that helps.
