The gym offers a world where each goal and each repetition is only as good as the exertion of energy of which you put forth. If you don't have a mind ready and willing to push through whatever difficulty you may have, then growth is simply not an option. That ability to regularly challenge yourself and to push past any possible hardships creates boldness. Because if you are in a daily routine of either denying yourself something (sweets) or putting more weight on your back (quite literally), you are training not only your body, but your mind and soul as well to see these as simply part of life. So, daily creating a more and more bold spirit will expunge any fear of standing out. Compared to the fear of not getting back up or possibly dropping weight on yourself, standing in front of others and boldly proclaiming truth will be easier. Holding onto something as small as fear of judging eyes will seem obtuse and unreasonable because the end goal is worth so much more than the shrinking unknown.
