There have been a lot of posts recently about lifting weights and protein shakes. I do a mix of cardio (biking and light running) and weights for the upper body. I also take in lots of protein, typically chicken breast, fish, breans and a little bit of red meat. I also drink a protein shake (whey) everyday. In the past two years, I put on about 10 lbs or so and I'm happy where I am (41yo, 5'11", 175lbs). Now I just want to crank up the intensity of my workouts to shape my body and not necessarily bulk up.
