Let’s All Take a Deep Breath

The video tutorial with Coach Sepides covers the importance of deep breathing exercises for lung flexibility and oxygen intake during workouts. It explains how oxygen is vital for the body during exercise, as it is delivered to the heart and muscles. The tutorial includes experiments to feel the heart and lung activity at different exercise intensities and discusses the importance of hydration. The 'talk test' is introduced as a method to gauge exercise intensity. The video concludes with encouragement to try different exercises and highlights the benefits of deep breathing.

• They strengthen the heart.

• They increase lung flexibility.

• They enhance digestion.

• They improve muscle strength.

Why do our bodies require more oxygen during exercise?

• To increase heart rate.

• To deliver oxygen to muscles and organs.

• To cool down the body.

• To improve digestion.

What happens to carbon dioxide during exercise?

• It remains in the bloodstream.

• It is pumped out by the heart and exhaled.

How can you tell if you are exercising too hard?

• You feel very thirsty.

• You can no longer carry on a conversation.

• You start sweating.

• You feel hungry.

What is the 'talk test' used for?
