Cardiorespiratory Exercise Analysis

I have concerns regarding my heart and lungs during my exercises. I can feel that my heart beat fast and that makes me hard to breathe. It happens even while I am practicing yoga poses. Therefore, I decided to focus on chapter 3, which is about cardiorespiratory endurance to gain more information as well as learn how to control it.
Chapter 3, Cardiorespiratory Endurance is describing how the body produces the energy it needs for exercise; listing the major effects and benefits of cardiorespiratory endurance exercises; explaining how cardiorespiratory endurance is measured and assessed; describing how frequency, time, and type of exercise affect the development of cardiorespiratory endurance; and the best ways to prevent, treat common injuries.
According to the information from the book, I build a plan for my own.
First, I learn about yoga and choose the best fit. There are many different types of yoga, I should choose the type of yoga suited to the body and goals of the workout to achieve the
highest efficiency. I choose to practice Hatha yoga. This exercise focuses on breathing and some basic postures. This type of yoga is best suited for me. Second, I make a schedule of practice yoga.

Each person has a different ability.
Depending on the physical strength of each person, I will choose the most appropriate workout period. It is important to practice regularly. I plan to exercise three times a week, as this is very feasible and I can do it, rather than planning my daily routines and feel frustrated when I cannot keep it up every day. Third, warm up and cool down. Proper booting can help my body move better and reduce the risk of injury. There are many startup exercises for me to choose from. The purpose of warm-up exercises is to activate all major muscle groups, heat up the muscles and stimulate the circulatory system. During the startup, I should also control the breathing to increase the effectiveness of the exercises, retreat and concentrate more. Fourth, regular exercise. I will make yoga a part of my daily lives. Once I get used to yoga daily and recognize yoga to improve my body shape and health, I will have more motivation and practice more
often. One last thing, the pose that I like the most and also good for the heart is Setu Bandha Sarvangasana. Lie straight, knees bent and feet placed on the floor with shoulders. Pull as close to the pelvis as possible. Breathe in, press my legs and arms on the floor and lift my hips. Not close to the butt. Hold hands together, lower my shoulders, press my legs and arms on the floor. Open the chest, pointing the front and pelvis forward. Hold for 5 breaths, exhale and lower down, and repeat 2-3 times. Its benefits are stretching the chest, neck, and spine. Help the brain relax and relieve stress, mild depression. Stimulates the abdominal, lung and thyroid organs. Reduce anxiety, fatigue, back pain, headache, and insomnia. Treatment of high blood pressure.
