You didn't provide us with any following statements? But a thing which is very important and is highly relevant for personal safety and is reflected as key decision when exercising would be that we always try to stay within the reach of our capabilities and don't try to show off in front of others which could negatively affect our performance over time.
It could be to avoid injuries. One reason why there are several rules in
exercising is to ensure that a person will not get injured during a
workout. Injuries can occur when one is
either handling too much weight, doing the exercise wrong, not using proper
equipment or does not have a partner or trainer assisting him.
