I like to lift weights, usually 4 or 5 days a week at the gym. I started it and maintained it statically since January, though I lifted my first dumbell in 5th grade. Since 5th grade I lifted off and on, so when I seriously started in January I had a nice base going. My favorite things to work are upper body. Biceps, triceps, pecs, delts, all those. I find working legs rather boring, but I do run sometimes. According to a bow-flex poster in my garage, the average guy can bench-press 93% of their body weight. I currently weigh 150 pounds, and can bench 180 or so, on good days, which is 120% of my body weight, so I must be doing something right. In case you are wondering, there is a purpose to this thread. First of all regarding supplements. Since January, I've been taking one or two servings of Six Star Advanced Whey Protein after my workouts. Is this really considered a supplement, because all it really is is pretein, right? Second, people say to work different parts of the body on different days, i.e. arms one day, chest and back the next, upper legs after that, etc. IS this really necessary?
