What should be avoided during stretching according to guidelines?

Holding your breath during stretching is discouraged because it can lead to increased tension in the muscles and potentially decrease the effectiveness of the stretch. Proper breathing is important during stretching as it helps to relax the body, increases oxygen flow to the muscles, and promotes a more comfortable and effective stretch. Breathing steadily can also help maintain focus and improve the range of motion.

In contrast, stretching cold muscles can result in injury, making it important to warm up before stretching. Using a partner for balance is a common practice in stretches that may require assistance, and stretching in the morning can be beneficial when done correctly, as the body may benefit from gentle stretching to start the day.
