Pre-workout supplements

Options
I am looking for a good PRE-workout supplement to add to my routine. Nothing too crazy, just looking for something that will give my muscles what they need/want more of during the workouts.

I am trying to cut my body fat (college beer gut, lol) and add some muscle size/definition. Workouts usually consist of strength training and 15-40 minutes of cardio.

Currently I am using Wheybolic Extreme 60 from GNC for post-workout and in the morning occasionally.



Anything you would like to recommend? Thanks!
