I've been going to the gym for about 3 months now and I've been wondering should I be stretching before lifting weights. I warm up with 20-25 minutes of elliptical and then go on to lifting. I have stretched before lifting weights, but i feel like it does nothing for me. I normally don't have any pains or soreness the next day. So I'm wanting to know does it actually do anything for increasing the amount weight you can do or is it just so you don't pull a muscle.
