Fitness, Bodybuilding & Protein: What Is Protein?

What is protein? Most people who work out and want to build muscle know that they need protein in their diet to achieve results, but what does it actually do and how does it work?

In this video we'll look at what proteins are and what they do in your body, how your body builds them with the help of amino acids and why you need proteins in your food when you are into bodybuilding and want muscle.

For those of you interested in the topic of soy limiting production of testosterone that is mentioned in the video, here is some scientific research on the subject:

Goodin S, Shen F, Shih WJ, Dave N et al. Clinical and Biological Activity of Soy Protein Powder Supplementation in Healthy Male Volunteers. Cancer Epidemiol Biomarkers Prev. 2007 Apr;16(4):829-33.

I was drinking soy milk right when you got to the part about the research that might have found a link with testosterone loss.

I proceeded to finish the glass because it is delicious.

This wasn't boring at all. This should be an essential video to every bodybuilder who cares about his nutrition!
