Tim D The toughest thing about working out that doesn't have to do with the actual physical activity part, is following a proper nutritional plan and sticking with it. It was the hardest thing I had to learn when I transitioned from playing sports to just regular training. But as I now know, its 150% crucial to the success of any program, for all you beginners don't skip this part. The second hardest part is the sleep and rest period; I know how one can overdo and push to the limits which I now know if you are exhausted does no good. Everyone keep up the good work, one day at a time!
