I go to gym on average six days a week.  On Mondays, Wednesday, & Friday I hit the weights.  I lift pretty heavy as I am genetically a thin guy and heavy weights low reps give me the size. I use mostly machines, as they are safer when you workout without a spotter.  I do have a Bowflex and a Elliptical Machine at home if I can't get the the gym, but I prefer the whole gym atmosphere.  Tuesday, Thursday, and Saturday I do Cardio Work, which can vary from Treadmills to Boxing based cardio DVDs. The key is always finding the "holes" in your workout and making it better and better.

THE DIET

I am definitely a high protein person, as I try to consume some form of protein six-seven times a day, and lots of veggies, and whole grain carbs.  I avoid the three enemies of any healthy lifestyle, white flour products, sugar and fat. I also do take various supplements from the health food store, an no I have never even thought of using steroids, as the long terms effects are simply not worth it.
