There is a principle in exercise called the principle of specificity. What it says is if you want to do a particular activity very well, you need to train specifically for it.

You'll see exercise artifacts from years ago, and then examples of modern equipment like Nautilus machines. It shows the progression of fitness equipment throughout the years.

The judges have full authority to exercise discretion. That's why they're there.

Diet got worse, people got less exercise, had less access to health care, there was a lower health insurance rate. Young adults drink more, smoke more cigarettes, use drugs.

People who get in trouble are those who try something new and go at it full throttle.

The body is always looking to adapt. When you throw something new at it, there are basically two roads for it to take: the correct one ? by easing into it and systematically increasing strength and endurance, or the incorrect one ? the body reacts, and that's injury.
