It is common knowledge that endorphins are released during an effective workout, such as strength and conditioning class
Strength and conditioning works to make your body stronger, providing you with the skills you need in order to create a more effective workout overall. When your core is strong, you will be able to transfer energy to the rest of the muscles, resulting in more powerful muscle contractions and quicker repetitions.
A strength and conditioning program or class will help train your muscles, allowing you to lift and hold your body upright in a much safer manner. With this in mind, you may actually appear taller and more confident, as opposed to hunched over and weak.
