How to prevent muscle soreness

Here's what I do:

1. Take a good multi-vitamin everyday
2. Drink LOTS of water
3. Have a good stretch post workout
4. Get moving! - Even though you are stiff and sore, go for a walk or a jog, it helps.

To be honest, I like to feel a little sore a day or two after a good workout, reminds me that I did something good!
